Requirements and

recommendations

Rear access required to make MV line and load cable connections.

Keylocks: It is important that the reduced voltage soft start (RVSS)standalone section interlock key be coordinated with a key interlock(key removable when disconnector is open) added to the maincontroller. This guarantees that the RVSS standalone section MVdoors cannot be opened unless the disconnector in the maincontroller is open. If the main controller is not a Schneider Electriccontroller, Schneider Electric recommended the RVSS key bepermanently attached (welded or solid riveted) to the main controllerkey. If the main controller is a Schneider Electric controller, then akey locking scheme should be ordered so the RVSS standalonesection interlock uses the main controller key.

The RVSS standalone section does not come equipped with power

fuses, main contactor, control power transformer (CPT),voltagetransformer (VT), and VT fuses. These components must be presentin the starter section.

Phasing between power supply, RVSS, and motor must be correctbefore applying power to RVSS.

Control power must be supplied to the RVSS prior to medium voltagepower being applied to the RVSS.

Current transformer (CT) is a maximum rating; e.g., 150:5 indicatesmaximum current 150 A. CT should be specified so that operatingcurrent is between 50% and 100% of rating.

Seismic certification of Motorpactmedium voltage motor starters

Motorpact medium voltage (MV) motor starters that are seismicallycertified have been qualified for the site-specific seismic requirements ofthe listed model building codes and standards. Optional constructionfeatures may be required, depending on the location of the installationand the particular code and standard of interest. Seismic certificates ofcompliance and equipment labels are provided with all seismicallycertified equipment. To maintain the validity of this certification, theinstallation instructions provided in this bulletin must be followed.

Responsibility for mitigation ofseismic damage

For the purposes of the model building codes, Motorpact MV motor startersare considered nonstructural building components. Equipment capacitywas determined from tri-axial seismic shake table test results as defined in

the International Code Counsel Evaluation Service (ICC ES) AcceptanceCriteria for Seismic Qualification Testing of Nonstructural Components(AC156). Unless otherwise indicated, an equipment importance factor of1.5 (IP =1.5) was used, indicating that equipment functionality was verifiedbefore and after shaker table seismic simulation testing. This importancefactor is indicative of critical facilities where maximizing the probability ofpost event functionality is a priority. AC156 is published by the ICC ES andhas been recognized by the Building Seismic Safety Council (BSSC) as anappropriate methodology in the 2003 National Earthquake HazardReduction Program (NEHRP) Commentary (FEMA 450 Part 2). TheNational Institute of Building Sciences established the BSSC in 1979 todevelop and promote regulatory provisions for earthquake risk mitigation at

the national level.

Incoming and outgoing cable and conduit must also be considered asrelated but independent systems. They must be designed and restrainedto withstand the forces generated by the seismic event without increasingthe load transferred to the equipment. For applications where seismichazard exists, bottom entry and exit of cable and conduit is preferred. Ifthe spectral acceleration value (Ss as defined by the InternationalBuilding Code or NFPA 5000) is in excess of 2.67g (such as the NewMadrid seismic area), then the equipment must also be braced at the topusing a lateral restraint system. A lateral restraint system is required insituations where horizontal motion at the top of the equipment is not bedesirable (such as applications where top entry and exit of conduit are

used). This system must be capable of transferring the loads created tothe load-bearing path of the building structural system.

Maintaining seismic certification Schneider Electrics seismic qualification of nonstructural components is justone link in the chain of responsibility required to maximize the probabilitythat the equipment will be intact and functional after a seismic event. Duringa seismic event, the equipment must be able to transfer the loads that arecreated through the mounting pad and anchorage to the loadbearing path ofthe building structural system.

The structural civil engineer or consulting engineer of record isresponsible for detailing the equipment connection and anchoragerequirements (including the lateral restraint system, if appropriate) for thegiven installation. The installer and manufacturers of the anchorage andlateral restraint system are responsible for assuring that the mountingrequirements are met. Schneider Electric is not responsible for thespecification and performance of these systems.

Cable installation Cables must be securely fastened or braced to withstand short circuitforces and to prevent strain on the terminals.

Maximum length of unsupported cable is 457 mm for line side cable and

1100 mm for load side cable.Connecting cables Before making cable connections, check to see if special site preparation

requirements are needed. Determine the phase identity of each cable.

Connections are labeled and viewed from the back, left to right,Load L3 L2 L1 Line L3 L2 L1. Load cables must be connected to the loadand line cables must be connected to the open side of the main contactorin the starter section.

Non-shielded cable Follow the cable manufacturers instructions for stripping back theinsulation and preparing the cable for the lug.

Shielded cable Follow the cable manufacturers instructions for stripping the shield andcleaning the unshielded portion of the cable. Install the appropriate stress

cone in accordance with the stress cone manufacturers instructions. It isrecommended to use a 229 mm maximum prefabricated stress cone. Followthe lug manufacturers instructions to attach the cable lug on the cable.

vo s arp u rns, corners, an e ges a cou amage or

weaken the cable insulation. Follow the cable manufacturersinstructions to determine the minimum bending radius of cables.

Ensure cables do no t come in contact with metal parts or opposite

phases.

Failure to fol low this instruction will increase the electrical stress on the

cable, shortening the life of the equipment.

Attaching MV line

and load cables

The MV cable connections are protected by an insulating barrier asshown. To attach the cable, the insulating barrier must be removed.

To attach MV line and load cables:

1. Remove the tie channel cover (10 screws).

2. Remove the upper and lower rear covers (4 screws). Use caution ascovers are heavy.

3. Remove the cable connection insulating barrier (14 nylon screws).

4. Attach the load (motor) cables to the connectors labeled "load."Attach the cables from the main starter contactor load side to theconnectors labeled "line." Attach the cables per the cablemanufacturers instruction. Conical washers placed on external sidesof the connectors and lugs ensure better distribution of stressregarding bolts tightened to recommended torques. Tighteningtorque: 50 Nm.

5. It is important to mount the cables vertically straight and not at anangle. It is also important to make sure the bolt is inserted correctlyso that it does not contact the insulating barrier. See Lug mountingbolt orientation on page 27.

6. Secure cables to cable support bar with cable ties or through plasticclamps on cable support bracket (unit specific).

7. Replace the insulating barrier. Tighten plastic screws and nuts.Secure nut to screw using Loctite425 Assure or equivalent

adhesive. Do NOT replace plastic hardware with metal hardware.8. Replace the upper and lower rear covers. Tighteningtorque: 35 Nm.

9. Replace the tie channel cover. Tightening torque: 35 Nm.

10.If applicable, remove old caulk from tie channel cover and apply newcaulk to seal tie channel cover.

There are minimal electrical clearances in this area. It is critical that

all barriers be reins talled after the MV cable connection is made.

Failure to do so can result in equipment damage or personal injury.

0Steps to be taken for testsand inspections

Power frequency testing

Perform a power frequency test on the customers line and loadcables before attaching the cables to the soft start section. Seetable below for power frequency test values.

Take the following minimum actions to help promote the safety ofpersonnel and equipment:

Restrict entry into the area to prevent any unauthorizedpersonnel from approaching the equipment during testing.

Notify all persons that the test is going to be conducted.

Follow all local lockout and tag-out procedures.

Remove all fuseslow voltage and medium voltage.

Disconnect surge arresters and surge capacitors (if supplied).

Disconnect or ground capacitive dividers (if supplied).

All ground connections must be properly made and tightenedaccording to torque specifications.

Do not use unfiltered, half-wave rectified dc power frequency testunits. Use of such devices greatly increases the chance of x-raygeneration.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC

FLASH

Only qualified electrical personnel should perform this

testing. During testing, maintain a minimum clearance of 6 feet

(1829 mm) from the equipment. Failure to follow these instruction

will result i n death or serious injury.

When performing power frequency testing of the soft start section:

1. Remove all medium voltage power fuses and VT fuses.

2. Place a jumper wire from the gate to the cathode on the gatedrive board (where the two white wires connect).

3. Place a jumper across each SCR.

4. Place a jumper across the ring transformer primaries andjumper to ground.

5. Place a jumper across the VT inputs and jumper to ground.6. Close the bypass contactor.

7. After completing power frequency testing make sure to removeall jumpers.

NOTE: For illustrations of shorting and grounding jumpers, seeSchneider Electric document no. 46032-700-20.

Phase-to-phase powerfrequency testing

Follow these steps to perform a phase-to-phase power frequencytest:

1. Perform a phase-to-phase power frequency test on the MVcable connection.

a. Gradually increase the voltage to the levels shown in thetable on page38.

b. Verify that the equipment sustains the specified voltage forone minute without flashover occurring.

2. Turn off the test equipment. Discharge to ground the phasecable connection before removing the test cables.

HAZARD OF ELECTRIC SHOCK

After completing power frequency testing, temporarily

ground MV cable connection to remove any residual

charges. Failure to foll ow this instruction can result in death or

serious injury.

POSSIBLE OVERVOLTAGE ON ELECTRONIC

COMPONENTS

Power frequency testing is conducted on the new soft

start section at the factory. For a new soft start section, power

frequency testing in the field is only necessary if repairs such as

replacing a SCR stack or similar activities occurred. If power

frequency testing is necessary, it should only be performed by

qualified, trained field service personnel. Failure to follow thisinstruction can result in equipment damage.

Phase-to-ground power

frequency testing

Follow these steps to perform a phase-to-ground power frequency

test:1. Perform a phase-to-ground power frequency test on the MV

cable connections.

a. Gradually increase the voltage to the levels shown in thetable on page38.

b. Verify that the equipment sustains the specified voltage forone minute without flashover occurring.

2. Turn off the test equipment. Discharge to ground the phasecable connection before removing the test cables.

If the test is unsuccessful, inspect the insulators for leakage paths.If necessary, clean the surface of the insulator(s) with denaturedalcohol and re-test. If problems persist, DO NOT ENERGIZE THEEQUIPMENT. Contact your local field sales office or yourdistributor.

If the equipment has been stored for several months or has beenexposed to high humidity during the storage time period, PERFORMA POWER FREQUENCY TEST. First energize the heater circuitsfor a minimum of 24 hours. See the table on page38for test valuesand additional information. Follow other equipment testingprocedures as required by customer in-house standards.

Final inspection

After installing the equipment and making all interconnections,follow the steps below to test the equipment and perform a finalinspection before placing it in service.

Verify that a power frequency test has been performed recently.If a power frequency test is required, see Power frequencytesting on page 38.

Check all control wiring with the wiring diagrams. Verify that allconnections are properly made and tightened, all secondaryfuses are installed, current transformer circuits are complete, allfault detection devices have been properly connected and set,and that loose connections are tightened to the propertightening torque.

Verify that all protective relays have been configured with propersettings per the outcome of customers coordination study.

Verify that all insulating surfaces, including the primary supportinsulators and isolation barriers, are clean and dry.

Verify that all primary fuses are installed and orientatedproperly and do not exceed the nameplate rating for theirsections. Fuses are located in a separate starter section.

Before energizing any source of electric power, make a finalcheck of the equipment. Inspect every compartment for looseparts, tools, litter, and miscellaneous construction items.

Verify that all barriers, covers, and doors are secured using theoriginal mounting hardware.

Verify RVSS MV doors are closed and locked and key has

been returned to starter.

ALWAYS assume that al l c ircuits are live unt il they

have been completely de-energized, tested, earthed,and tagged.

Follow all lock-out / tag-out procedures. If disconnect switchescannot be opened, disconnect the line leads.

The following operations must onl y be carried out after

power frequency tests and before the equipment is

energized.
