The Green Mains LED will be illuminated whilst the mains supply is present. In the event of a fault condition, the Yellow Fault LED will be illuminated. The Orange Battery Charging LED will be illuminated when the battery is not fully charged and is charging normally. When the battery is fully charged it will be extinguished. ## INSTALLATION AND SET-UP This unit is only suitable for installation as permanently connected equipment. The PSU is NOT SUITABLE for external installation. EQUIPMENT MUST BE EARTHED. Before installation, ensure that external disconnect device is OFF. The PSU should be installed according to all relevant safety regulations applicable to the application. ## Module Enclosure & Mounting This power supply module has high voltage present and is for use by Service Personnel only. This power supply module MUST be securely mounted within a robust enclosure having suitable means to prevent unintentional access to the module. Suitable notices must be affixed to the outside of the enclosure to warn of high voltages present internally. ## Mounting - 1) Mount securely in correct orientation allowing minimum clearance of 20mm all round – see diagrams below. - 2) The G2401BMU and G2402BMU modules have the option of either being DIN rail mounted (using the integrated DIN rail mount) or by using appropriate fixings using the four available mounting lugs. The G2403BMU and G2405BMU modules are fixed using the three available mounting points. **==> picture [218 x 67] intentionally omitted <==** **----- Start of picture text -----**

©2013 ELMDENE INTERNATIONAL LTD PAK200567_01A 4 ## INSTALLATION AND SET-UP CONTINUED ~~Es~~ ## Mains Power Up - 3) Attach correctly rated mains cable (minimum 0.5mm[2] [3A], 300/500Vac) and secure in enclosure using cable ties. - 4) Apply mains power. Check for 27.6Vdc on load outputs. Check Green Mains LED is on. - 5) Disconnect mains power. ## Load Output - 6) Attach correctly rated load cable and secure in enclosure using cable ties. Note polarity. - 7) Apply mains power. Check green Mains LED is on. - 8) NOTE: Yellow Fault LED may flash to indicate no battery has been connected; this is normal. - 9) Verify load is operating correctly. - 10) Disconnect mains power. ## Signalling Outputs - 11) Connect EPS and GEN fault outputs to appropriate inputs of control equipment. ## Standby Battery - 12) Connect battery to terminal block using minimum 32/0.2 (1.0mm[2] CSA) stranded wire. NOTE: ensure correct polarity of battery connections. Maximum recommended total battery lead length = 500mm - 13) Apply mains power. Check Green Mains LED is ON. Check Orange Charging LED is ON. - 14) Check there is no fault indication on Yellow LED. - 15) Disconnect mains power. Check that the batteries continue to supply voltage and current to the load. Check Green Mains LED is OFF and the control panel displays a Loss of Mains (EPS) fault NOTE: Batteries must have sufficient charge to supply the load - 16) Reconnect mains power. Green LED should be on. - 17) Remove Load fuse. Check Yellow Fault LED is ON and control panel shows General PSU fault. - 18) Replace Load fuse. Check Yellow Fault LED is OFF and General PSU fault has cleared at control panel. ©2013 ELMDENE INTERNATIONAL LTD PAK200567_01A 5 Module Dimensions **==> picture [233 x 182] intentionally omitted <==** **----- Start of picture text -----**

Reference should be made to the battery manufacturer’s documentation to determine typical/expected battery life with a view to periodic replacement of the battery. If the output of the PSU fails the cause of the failure should be investigated e.g. short circuit load. The fault should be rectified before restoring power to the PSU. The fuses may need to be replaced. Ensure the correct fuse rating and type is used. ©2013 ELMDENE INTERNATIONAL LTD PAK200567_01A 7 ## COMPLIANCE is This product meets the essential requirements of the following EU Directives: Low Voltage: 2006/95/EC EMC: 2004/108/EC RoHS: 2002/95/EC WEEE: 2002/96/EC ## DISPOSAL OF PRODUCT AT END OF LIFE as This product falls within the scope of EU Directives 2002/96/EC Waste Electrical and Electronic Equipment (WEEE) and 2006/66/CE (Battery).
