3.6Turning off the PMM module

1. Open ("O" or OFF position) all the circuit breakers on the output circuits.

2. Open ("O" or OFF position) circuit breaker Q2 4 .

3. In a module with an isolation transformer, open ("O" or OFF position) circuit breaker Q1 5 .

4. Open the upstream switching device of the installation on the circuit supplying the PMM. LED 17 and the display go off.

Caution: dangerous voltage levels are present inside the PMM, even if Q1 and Q2 are open.
