6.3.5.6. Power

1. Pass the power cables through the access hatch to the power box of the generating set (AIPR or console, depending on the

generating set).

2. Connect the power cables to the busbars.
3. Connect the power cables to the application.

Check that the direction of rotation of the phases between the generating set and the application is the
same.

Important

Type of cables:

Use H074NF type cables according to the standards in force in the country of use of the generating set (In
France refer to the standard C15.100).

6.3.5.7.

Client terminal block

Refer to the wiring diagrams according to the configuration selected and the requirements.
