1 SPECIFICATION SHEET See Test, Inspection and Setting Sheet supplied loose with the system. Refer to drawings for dimensions, weights and electrical ratings. 2 GENERAL INFORMATION Application Suitability • MiniPurge Interface Units (MIU) are certified for use in Hazardous Locations, where the
Hazardous Location is non-mining (i.e. above ground) and where the hazard is caused by flammable gases, vapours or combustible dusts.
• The MIU can be located in Zone 1, 2 for gas and / or Zone 21, 22 for dust, or Class I, Division 1, 2 for gas and / or Class II, Division 1, 2 for dust Hazardous Locations.
• MiniPurge Interface Unit may be used for hazards of most gas or dust groups. However, apparatus associated with the MIU, such as intrinsically safe signalling circuits and other flameproof enclosures containing switching devices may be limited in their own group. The certification documentation supplied with such devices must be checked to ensure their suitability.
• As with all equipment for use in Hazardous / Classified areas, local working and installation practices for Hazardous Location equipment must be adhered to when installing and maintaining this equipment. This equipment must only be installed by personnel who are aware of the requirements for installation of electrical equipment within hazardous locations.
• MIUs are designed to be controlled primarily with compressed air. Where compressed inert gases are used (Nitrogen, for example) the user must take suitable precautions so that the build up of the inert gas does not present a hazard to health. Consult the Control of Substances Hazardous to Health (COSHH) data sheet for the gas used or relevant national requirements.
• The following materials are used in the construction of MiniPurge Interface Units. If substances that will adversely affect any of these materials are present in the surrounding environment, please consult EXPO for further guidance:
Stainless Steel Brass Aluminium ( Ex d / Xp enclosure contains <1% magnesium) Nitrile (‘O’ Rings)
• This equipment is designed for use under normal industrial conditions of ambient
temperature, humidity and vibration. Please consult EXPO before installing this equipment in conditions that may cause stresses beyond normal industrial conditions.
System Description • EXPO range of MIUs is designed for use on a wide range of applications and enclosures.
They are to be used in conjunction with a system, which provides the MIU with the necessary signals in order to produce “Volt Free / Dry Contact” alarm signals and power switching to the pressurized enclosure.
• All units are built into flameproof / explosionproof enclosures. The joint between the lid and the enclosure forms a threaded flamepath.
ML303 v18 09-Dec-15 Page 3 of 10
• Each MIU is supplied with limited entries (refer to the drawing section for details). When additional entries have been ordered, the following restriction will apply:
o Minimum space between entries; 35mm, (1.38”) for M20 or ½” NPT 40mm, (1.58”) for M25 or ¾” NPT
o Entries should not be placed so close to the side that an internal surface, parallel to the thread of the entry, is cut when a threaded entry is machined.
• For USA (NEC) or Dual standard conformity, NPT entries must be used. • For IEC / ATEX, metric or NPT entries may be used. NPT and Metric entries must not be
mixed on the same enclosure. • The standard MIU is supplied with NPT entries. • Alternative versions of MIU are available which use intrinsically safe or increased safety
switching systems to control the MIU functions. These are only available to special order. Contact the sales office for details.

3 INSTALLATION • MiniPurge Interface Units are designed to be mounted in hazardous / classified locations.
The MIUs are suitable for use in the following area classification. Please note that the gas group varies for European / USA area classifications. IEC / Europe
Zone 1, 2 Zone 21, 22
Gas Group IIC Dust
USA/ Canada Class I, Divisions 1 & 2 Class II, Divisions 1 & 2
Gas Groups B, C & D Dust Groups E, F & G
• The MiniPurge Interface Unit shall be installed in accordance with relevant standards,
such as EN 60079-14 or NEC 500 or 505, and / or any local codes of practice that are in force.
• The distance required free from obstructing the flamepath for ATEX / IEC: Gas Group IIC is at least 40mm (15/8”). Gas Group IIB is at least 30mm (1 11/64”) Gas Group IIA is at least 10mm ( 17/64”)
• Cable glands, conduit or other cable entry devices shall be appropriately certified and suitable for the cable and the conditions of use and be installed in accordance with the manufacturer’s instructions. EN 60079-14 contains guidance on the selection of appropriate cable glands.
• When the MiniPurge Interface Unit is to be used in conjunction with a MiniPurge Purge and Pressurization System, it shall be connected in accordance with the instructions given in this manual.
• The external earth connection of the MiniPurge Interface Unit shall be connected to earth using a minimum 4mm2 / 12 AWG conductor.
• It is recommended that 6 mm / ¼” dia non-crushable pipe with appropriate 1/8” NPT fittings (not supplied) are used to connect the MIU with the MiniPurge system. To order suitable fittings and pipe to connect the two units see Spare Parts - Additional Items.
• MiniPurge Interface Units are supplied with NPT tapped cable entries as standard.
• In the MIU/dA, Power Contactor is operated directly by the pneumatic (input) Actuator.
• In the MIU/dX, connect the external voltage between the terminals N and 115 or 230 terminals, for 115 V or 230 V ac Power Supply respectively.
• In the MIU/dT, connect the external voltage to the L and N terminals, and select the appropriate supply voltage using the voltage selector switch, for 115V or 230V ac supply respectively.

ML303 v18 09-Dec-15 Page 5 of 10
4 COMMISSIONING • Once the MIU has been installed, the cable glands, conduit, earth connections and any other
connections (e.g. pneumatic) shall be inspected for correct installation before the unit is put into service.
• Apply a thin, even layer of the grease (provided) onto the threads of the lid. • The lid shall be correctly fitted and the lid locking device secured. • If the commissioning is being carried out in the Hazardous Location, appropriate precautions
must be taken to prevent an incident. A relevant “Hot Work Permit” or similar must be obtained from the appropriate authority and regulations followed.
Commissioning the MIU when installed with a MiniPurge Control System • Commissioning the MIU requires a working pressurized enclosure and MiniPurge system.
For operation and commissioning instructions for the MiniPurge system, refer to the appropriate manual supplied with the MiniPurge. The description below assumes a standard Leakage Compensation MiniPurge is in use.
• Operation of the Alarm / Pressurized contact can be tested as follows: • With the air supply turned off, there should be continuity between the A and C terminals, and
no continuity between the C and P terminals. • Close the enclosure door, and turn the air supply on. The purge should begin, and the
Pressurized indicator on the MiniPurge should change from “Red” to “Green”. There should now be continuity between the C and P terminals, and no continuity between the C and A terminals of the MIU.
• Operation of the power switching contacts can be tested as follows: • With the air supply off, the power switching contacts should be open circuit. Remember to
turn on the power supply, for units that require a power supply to control the switching (MIU/dX and MIU/dT units).
• Close the enclosure door. Turn on the air supply. The purge cycle should begin. • Once the purge cycle has been completed the power switching contacts will close. Both
pneumatic connections between the MiniPurge and MIU are now pressurized, • Ensure the pneumatic connections do not leak. • The final check is the most important and must not be ignored. The enclosure should be
pressurized, a purge cycle completed and the power contacts closed. Turn the air supply to the MiniPurge off. After a few seconds the enclosure will lose pressure and the following should happen
o The Pressurized indicator on the MiniPurge should change from “Green” to “Red”. o The power contacts should open disconnecting power to the enclosure. o There should be continuity between the A and C terminals, and no continuity between
the C and P terminals. o The above assumes the MiniPurge system is set to “Alarm & Trip” (i.e. Disconnect)
not to “Alarm Only” • If the final check has been completed successfully, turn on the air supply to the MiniPurge.
ML303 v18 09-Dec-15 Page 6 of 10
5 MAINTENANCE EXPO suggests at a minimum of every six months and /or a maximum of 2 years dependent on site conditions, to follow the maintenance routine described below: • Inspect the condition of the enclosure and associated cable glands, conduit for any signs
of damage. • Inspect the condition of the thread and the lid locking device for any signs of corrosion or
damage. • There are no user serviceable parts within the MIU system apart from those mentioned in
this manual. • Repeat the commissioning tests to check correct operation of the system. • Check that the air supply quality, where applicable, is still acceptable. • Check that the system has not been modified in an unauthorised manner. • Check that the certification labelling is legible and that the system is suitable for the
hazardous location.
ML303 v18 09-Dec-15 Page 7 of 10
6 FAULT FINDING Refer to the table below to solve any malfunction. Problem Potential Cure The Alarm/Pressurized contact fails to operate.
• Check the pneumatic connection from the MiniPurge for leakage / blockage.
• Check the operation of the pneumatic feed through as follows:
• Unscrew the air connection to the Feed Through Actuator on the side of the MIU, and use a small terminal screwdriver to manually depress the piston inside the feed through.
• Pressing the piston should transfer the motion to the switch within the MIU, and the change-over action of the switch should be observed with a continuity tester.
The power switching contacts do not close. (MIU/dA units)
• The contactor is directly operated by the pneumatic Feed Through Actuator. Operation should be tested as outlined for the alarm contact above.
The power switching contacts do not close (MIU/dX and MIU/dT units)
• Check that there is power supplied to the MIU • Check operation of the pneumatic Feed Through
Actuator as above for the Alarm/ Pressurized contact. • Check the voltage selection matches that of the supply • Check the fuse in the MIU. (Refer to the circuit diagram
for the fuse rating.)
