3.3 Electrical Installation

A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local
regulations.
In order to maintain the IP rating of the generator, all cables entering the electrical enclosure must do so through the dedicated cable glands
located on the side of the generator.
Refer to the wiring schematics at the rear of the manual for details of the required terminations. All terminals are identified in the image below.
