The cabinet should be attached to the base with M10 or M12 anchor bolts,nuts, and washers (4 pcs each). The recommended anchor bolt length is60 mm (2.36 inches). Anchor bolts and nuts are not provided with thedelivery and must be acquired locally.

Before you start

Check that the base is planned and prepared.

Steps

1. Pull out the back stop.

2. Attach the cabinet to the base.

An anchor bolt should be protruding up through each bolting hole.Secure the nuts and washers to the bolts and tighten to therecommended torque.

Attach the cabinet with four bolts, nuts and washers. Adjust theheight of the nuts so that the cabinet is level.

DN7064519Issue 3 en18/06/2008



Figure 10. FCIA anchor holes

Tip

When considering if the cabinet is level or not, a useful test is to checkthat the door of the cabinet closes properly. If the door does not closeproperly, the cabinet is not level. Another way is to use cross-measureto verify that the cabinet is level.

Warning

Danger of hazardous voltages and electric shock! When installingthe battery bridges, make sure the tool does not touch metal.

8.2.3 Installing MIBBU WPUB (469784A) and WPUC (469955A)

Purpose

The Power Distribution Unit (PDU) is utilised in Flexi Cabinet for Indoor(FCIA) when battery backup is used. Either WPUB or WPUC can be used.



The PDU converts the AC power into DC power, which the base stationuses.

Install the PDU in the top 3U of the cabinet so that the AC terminal can bemounted on the roof.

Before you start

Prepare DC cables for both the batteries and System modules.

. Other half of battery cables from Installing batteries in FCIA

. One set of DC cables from PDU to the System module. 4 AWG (25 mm2). 1500 mm (78.7 in.). 2 extra cable lugs with M10 rings are required

. Open the PDU and take out the installation parts.

. Connect the power cables to the PDU before installing it in the rack.

. Check that the alarm polarity is correct. The default setting for thealarm polarity is Normally Open. If you need to change it, seeChanging the alarm polarity for the WPUB unit or Changing thealarm polarity for the WPUC unit, depending on your base stationsetup. Remember also to change the Intelligent Shutdown polarity, ifusing it.

Caution

Risk of short circuit. Make sure that all the breakers on the powerdistribution unit (PDU) front panel are in the OFF position before youconnect the cables.

Steps

1. Remove the plastic cover from the back of the PDU.

8.2.4 Installing rectifier units (WPMB/WPMC)

Purpose

The PDU provides four slots for rectifiers. Each of the PDU versions(WPUB/WPUC) has its own rectifier unit: WPMB/WPMC. Install therectifier units as described in these instructions.

Before you start

Remove the dummy panels from the PDU.

Steps

1. Install the rectifier units.

Install the rectifier units in their places. Note that if the rectifier is thetype that has the retaining hooks (WPMB), the hooks must be in anopen position before fixing the unit in place. Use a small screwdriverin the holes in the upper left- and right-hand corners of the unit torelease the hooks.



Figure 25. Installing the rectifiers, WPMB (top) and WPMC (bottom)

2. Secure the units.

When the unit is in place, tighten the knurled-head fixing screw orinsert the retaining hooks in their slots, depending on the unit typeused.

Caution

The retaining hooks are fragile. Do not carry the unit by the retaininghooks.

3. Switch on the breakers on the PDU front panel.

Turn the breakers on the PDU front panel into the ON position.

Warning

Risk of electric shock. Do not switch on the breakers before thebase transceiver station (BTS) installation is complete.

4. Close the lid.

8.2.5 Connecting battery backup alarms in FCIA

The alarm system for the batteries is “plug and play”. No configuration orconnection to an external alarm box is required if the default alarms areused and the EBCA cable is used. The EBCA cable connects from theEAC connector on the PDU to the FPA connector on the System module.See the following figure for an illustration on connecting battery backupalarms in FCIA.



Figure 26. Connecting battery backup alarms in FCIA

Note that the FSEB is not required for battery backup alarms in FlexiEDGE FCIA configurations because the default alarms are routed to theSystem module with the EBCA cable.

The default alarms are:

. Mains 1 - Mains breakdown with battery backup



. PSM 1 - Site powering faulty

. PSM 2 – Site powering operation degraded

. PSM 3 – Site powering notification

If it is required to change the default PDU alarm configuration, a customcable is needed to connect from the PDU alarms to the FSEB or otherexternal alarm box. For more details about the PDU alarms, see theWPMB/WPMC description in the Nokia UltraSite WCDMA Base StationOptima Compact Outdoor (WREB) product documentation.

Steps

1. Connect the EBCA cable from EAC connector on the PDU to theFPA connector on the System Module.

2. Tie the cable to the side of the cabinet.

8.2.6 Changing the alarm polarity and disabling the LTE distribution alarmof the WPUB unit

Purpose

The EAC alarm polarity can be set to two states, Normally Open orNormally Closed.

The Normally Open state means that the galvanic EAC alarm circuit loop isopen and electric current is not flowing through it. The corresponding EACalarm is activated if the EAC alarm circuit loop is closed.

The Normally Closed state means that the galvanic EAC alarm circuit loopis closed and electric current is flowing through it. The corresponding EACalarm is activated if the EAC alarm circuit loop is opened.



The default alarm polarity is Normally Open. Make sure that you set theEAC alarm polarity correspondingly during BTS commissioning.

Before you start

If changing the polarity is needed, it is recommended to do this beforeinstalling the WPUB unit into the cabinet.

Caution

Always use an ESD wrist strap when handling units labelled with theESD sign. Labelled units are sensitive to electrostatic discharge.

Steps

1. Lift off the plastic cover on the backside of the WPUB unit.

2. Remove the screws that attach the cover to the unit and lift offthe cover.

Remove the four screws on the top and three uppermost screws oneach side of the unit.

Note that disabling the LTE distribution alarm does not requireremoving the cover.

3. Move the position of the jumpers so that the required alarmbehaviour is met.

The text on the interface board shows how the jumpers should bemounted for Normally Open (NO) and Normally Closed (NC) states.

4. Disable the LTE distribution alarm if needed.

To disable the alarm, connect the wire between the pins 10 and 11 ofthe CON41 connector.

Disabling LTE alarm



8.2.7 Changing the alarm polarity and disabling the LTE distribution alarmof the WPUC unit

Before you start

There are eight galvanic isolated alarm contacts for remote supervision ofthe alarms. Each alarm contact represents different alarm conditions.Alarm relay coils are powered during normal operation. All alarm relays willgive an alarm with no AC or DC power connected to the system.

Figure 28. Alarm connection, 9-pin D-sub

Tip

If changing the polarity and/or disabling the LTE distribution alarm isneeded, it is recommended to do this before installing the WPUC unitinto the cabinet.

Caution

Always use an ESD wrist strap when handling units labelled with theESD sign. Labelled units are sensitive to electrostatic discharge.

Steps

1. Loosen the fixing screw and pull out the alarm interface unitusing the handle.

2. Use JP8 for setting the alarm relays to closed on alarm or openon alarm.

The jumper mounted between pins 1 and 2 on the jumpers (default)means closed on alarm for the corresponding relay.

The jumper mounted between pins 2 and 3 on the jumpers meansopen on alarm for the corresponding relay.

The jumper numbers correspond to the relay numbering (forinstance, JP5 to RL5).

Note that when the jumpers are mounted between pins 1 and 2, thealarm polarity is Normally Open. When the jumpers are mountedbetween pins 2 and 3, the alarm polarity is Normally Closed.



Figure 29. Alarm interface unit from above

3. Disable the LTE distribution alarm if needed.

LTE distribution alarm is controlled with the jumper JP4.

As default, the alarm is active and the jumper is mounted betweenpins 1 and 2. Mount the jumper between pins 2 and 3 to disable thealarm.

4. Reinstall the alarm interface unit.
