3.4 Electrical Installation

A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local regulations.

3.5 General Requirements

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. All cables used must be sized such that the voltage drop between
the supply and the load does not exceed 5% of the nominal voltage under normal
conditions. All cables external to the generator must be adequately supported
and protected against physical damage.
When connecting to terminal blocks always ensure that the conductors are fully
inserted into the terminal, and the terminal screws are firmly secured. We
recommend that individual conductors are cable tied together so that, in the
event of on conductor coming loose, they cannot touch other parts.

The generator requires a 100 - 240Vac single phase electrical supply in
accordance with local wiring regulations. Refer to the technical specification for
voltage and frequency tolerances.
Connection to the electrical supply should be made through a switch or circuit breaker rated at 250VAC, 6A with a minimum short circuit rating of
10KA. All of the current carrying conductors should be disconnected by this device. This protection should be selected in accordance with local
and national code regulations.
The device chosen should be clearly and indelibly marked as the disconnecting device for the equipment and be located in close proximity to the
equipment and within easy reach for the operator.
Over current protection must be fitted as part of the building installation. This protection should be selected in accordance with local and national
code regulations with a minimum short circuit rating of 10KA.
The protective earth conductor should be longer than the associated phase conductors so that in the event of the cable slipping in the cable
gland, the earth will be the last to take the strain.
Note. If using flexible cable please ensure that it conforms to the requirements of IEC60227 or IEC60245.
