1. Presentation 1.1 250 A PMM modules You can choose from 6 different modules depending on: ◗ the number of output circuits required and the type of protection (126 standard circuit breakers or 60 circuit breakers with earth-leakage protection), ◗ the presence of an isolation transformer, ◗ the depth (825 with or without an isolation transformer and 425 without).

1. Presentation 1.3 Access to connections Remove the eight cover panels (each secured with two screws).
2. Installation 2.1 Setting up the module Module 825 mm deep 1. Install the lower base panels 23 on the sides that will not be accessible (not mandatory). 2. Position the module. 3. Level the module using the adjustable feet 24 . 4. Install the lower base panels 23 on the visible sides. ≥400 mm Connection cables run under the false floor or in a cable trough. Important. At least 400 mm of free space is required above the module to ensure correct ventilation.
2. Installation Module 425 mm deep Installation against a wall Caution: during handling, make sure the module does not fall over. 1. Turn to horizontal position the two brackets 25 at the back used to secure the module (see figure). 25 26 ≥ 400 mm 1250 1685,5 2. Install the rear base panel 23 (not mandatory). 3. Position the module. 4. Level the module using the adjustable feet 24 . 5. Attach the module to the wall using the two rear brackets. 6. Install the base panels 23 on the sides and front. 7.
2. Installation Back-to-back assembly Caution: during handling, make sure the modules do not fall over. 1. Remove the brackets 25 on the back of the module (used only for securing the module to a wall) and retighten the fixing screws. 25 25 2. Position the modules and use the brackets 26 on the top to interconnect the two modules (see figure). 26 3. Level the modules using the adjustable feet 24 . 4. Install the base panels 23 on the sides and fronts.
2. Installation 2.2 Input power connections Specifications for protection devices and cables are provided in section 6 (Appendices, technical data sheet). To access the connections, see section 1.3. Connection cables are not supplied. Module with isolation transformer Q1 1. Connect the PE or PEN protection cable to the earthing bar at the bottom of the module. 2. Remove the bottom cover on circuit breaker Q1. 3.
2. Installation Module without isolation transformer, combined earth and neutral (TNC system) Q2 1. Connect the PEN protection cable to the earthing bar at the bottom of the module. 2. Remove the bottom cover on circuit breaker Q2. 3. Connect the three phases of the input power cable to the bottom terminals of circuit breaker Q2 (without removing the control wires that are already connected). 4.
2. Installation 2.3 Output circuit connections It is advised to use crimped ferrules on the phase wires and lugs on the earth wires. 1. Connect the earth wire of each output cable to the earth connection bar located to the left of the metal trunking. 2. Connect the phase and neutral wires to each circuit breaker. 3. Tie the cables to the metal trunking. Note: it is advised to make the connections from the top down. Ph 2 1 N Q2 2 3 Q1 2.4 Alarm and remote shutdown connections 1.
2. Installation 2.5 Communication connections RS-485 RS-232 1. Connect the communication cable to the RS232 or RS485 connector on the righthand door of the module. 2. Run the cable as shown in the figure opposite. 3. Tie the cable down to the module frame.
3. Operation 3.1 Turning on the PMM module 1. Close the upstream switching device (external and not supplied) on the circuit supplying the PMM module. 2. In a module with an isolation transformer, close ("I" or ON position) circuit breaker Q1 5 (see page 7) . 3. Make sure disconnector-fuses F1 and F2 are closed and close ("I" or ON position) circuit breaker Q2 5 (see page 7) . ◗ The system status LED 17 (see page 8) flashes yellow a few seconds, then green and should subsequently remain green.

GENE MCM KWH 0000.0 KW 0000.0 Measurement units: KWH: total energy consumed by the PMM module in kWh. This value can be reset via the communication function. KW: total active power drawn by the PMM module in kW.
3. Operation 3.5 Setup Access setup mode by pressing simultaneously the SELECT DOWN DOWN SELECT UP UP UP + DOWN buttons and then entering the password: . This mode presents the functions listed below. View System Info, Find Meters and Review Meters : these functions are reserved for MGE UPS SYSTEMS. Setup Communication : access to the communication settings.
4. Maintenance 4.1 Trouble-shooting and solutions Alarm Meaning Action WARNING The current on the indicated output circuit is between 60 and 80% of the maximum value for the circuit. Monitor the power drawn on the circuit and avoid adding other loads to the circuit. ALARM The current on the indicated output circuit is higher than 80% of the maximum value for the circuit. Turn off certain loads connected to the circuit until the fault disappears (after alarm reset).
