It will then be easier to slide the replacement module into the connectors of the Input/Output box.
2. Installation 2.4 Communication ports Comet EX RT provides 3 communication methods that can be used simultaneously: ◗ The COM port provides RS232 communications using MGE UPS SYSTEMS SHUT protocol. Compatible with most power management software applications available into the enclosed Solution Pac CD-Rom. ◗ The output contact port is used for basic signaling or for protection of IT systems like IBM iSeries (formerly AS400) and more.
2. Installation Remote Power Off communication port 3 Used in conjunction with the optional EPO battery module, this port enables total isolation of all power sources connected to the UPS in case of emergency (the cable is not provided). Remote power off contact normally open RJ11 Remote power off contact normally closed RJ11 654321 654321 5 V DC to 27 V DC 5 V DC to 27 V DC ◗ Signal: - activation voltage: 5 V DC to 27 V DC. - current: 10 mA max.
2. Installation 2.5 Installation depending on the system earthing arrangement (SEA) Comet EX must be fed from a 3-phase source with neutral.

2. Installation 2.7 Connections of input/output power cables This type of connection must be carried out by qualified electrical personnel. Before carrying out any connection, check that the battery circuit breaker 12 and that the upstream protection devices (Normal and Bypass AC sources) are open ("0"). ◗ Comet EX RT UPS always comes from factory with Normal and Bypass AC inputs already connected together, using a bridge. ◗ Use included insulated ferrules with stranded wires.

2. Installation Connection of CLA module 29 BATTERY 28 _ + AC INPUT N L NORMAL To battery BY PASS AC Input Connect the battery cable 28 (provided with the CLA module) between the power module and the CLA module. Connect the cable 29 (provided with the CLA module) between the power module and the CLA module. ◗ Connect the battery: ◗ Cable cross-section (not provided): 10 mm2, solid or stranded wire (maximum 13 mm2 or AWG 6). ◗ Use a circuit-breaker (curve B, 50 A) for cable protection.
3. Operation 3.1 Initial start up Check that the manual bypass switch 7 is on Normal position. Set the normal AC source circuit-breaker 9 to the "I" position. Set the battery circuit breaker 12 to the "I" position. 15 The load is powered via the bypass AC source, but not protected by the UPS. Batteries are recharging, an eight-hour recharge period is necessary to get full backup time. LED 15 is ON.
3. Operation ON/OFF features Factory setting Function Options Comments Cold start Disabled Enabled Start on battery. Forced reboot Enabled Disabled Enables automatic restart of the system even if normal AC source is restored before the end of the shutdown sequence. Automatic restart Enabled Disabled Sleep mode Disabled Enabled UPS ON/OFF by software Enabled Disabled UPS restarts automatically when normal AC source is restored. Automatic shudown on battery if output load level < 10%.
3. Operation 3.3 Operating modes Normal (double conversion) mode This is the standard operating mode, set by default in the factory. Two possible choices. 13 1 - Normal AC source available: LED 13 is ON. The load is protected by the UPS. LOAD LEVEL 4 kW / 5 kVA OFF ON 19 13 20 Scroll up 19 and scroll down 20 function buttons allow you to read the UPS measurements (Normal AC source voltage, Bypass AC source voltage, operating mode, battery capacity and UPS Serial Number).
3. Operation 3.4 Operation on battery power The load continues to be protected by the UPS when the Normal AC source is not available. Power is supplied by the battery. Transfer to battery power 13 LED 13 is ON. LED 14 is ON. The audio alarm beeps every 10 seconds. 14 The load is supplied by the battery. The display indicates the battery remaining backup time. BACKUP TIME 10 minutes OFF ON Threshold for the low-battery warning 13 LED 13 is ON. LED 14 flashes. The audio alarm beeps every 3 seconds.
3. Operation 3.6 Shut down 1 - Press the OFF button 18 more than 3 seconds. 15 The load is no longer protected by the UPS. It is powered via the bypass AC source. If the UPS is set in frequency converter mode, the load will not be powered. If the bypass AC source is out of tolerance, the UPS will generate a 10 ms output calibrated break. LOAD LEVEL 4 kW / 5 kVA OFF 18 2 - Set the battery circuit breaker(s) 12 to the "0" position. 3 - Set the Normal AC source circuit-breaker 9 to the "0" position.
4. Maintenance 4.1 Troubleshooting If any of LEDs 15 or 16 is on, there is an operating anomaly or an alarm. Use "scroll up" or "scroll down" function button to reset the audible alarm. Troubleshooting not requiring MGE UPS SYSTEMS after-sales support: Correction Signification Indication Led 15 is on, AC source is not connected the alphanumeric display shows: to the correct terminals. Rewire correctly the normal AC source. BAD CONNECTION REWIRE AC NORMAL Load supplied by bypass AC source.
4. Maintenance 4.2 Hot-swapping the power module This operation can be performed without interrupting the load. Disconnecting the power module Stop the UPS with the OFF button 18 (press more than 3 seconds). Check if UPS is on bypass AC source: led 15 is on (If led 15 is not on, do not turn the manual bypass and call the after sales support department). ◗ Turn the manual bypass switch 7 to the BYPASS position. ◗ Switch the battery circuit breaker (s) 12 to the "0" position.
4. Maintenance Reconnecting the power module 13 Secure the Input/Output junction box using the three screws. Reconnect the battery cables 28 and 29 to the power module. ◗ Switch the battery circuit breaker(s) 12 to the "I" position. ◗ Switch the Normal AC source circuit-breaker 9 to the "I" position. ◗ Turn the manual bypass switch from the BYPASS to the NORMAL position. ◗ Check that the led 15 is on. ◗ Follow initial start up sequence (see section 3.1) in order to personalize the UPS.
