Unless specified otherwise, the maximum short-circuit current tolerated by the equipment is less than 10kA.
Electrical maintenance
Any equipment inspections and verification must be carried out solely by specifically trained personnel and
always in strict compliance with safe working practices.
N.B.
Normally, the automatic electrical panel used for the network-unit transfer switch is subjected to
three power sources, that is:
the network, generator and auxiliary power lines,
therefore it is
fundamental to take specific precautions before accessing the system.

Unit start-up/shutdown
Before starting-up the unit, check that all the above-mentioned preliminary operations have
been implemented and the unit can function at maximum efficiency (water, oil, diesel, battery).
Before connecting the load, verify the phase sequence corresponding to the rotation direction
of the machinery.
All generators are delivered with proper rotational speed, frequency and voltage settings.
Tampering is prohibited. The generator can cease to function properly if the manufacturer settings
are changed, causing sudden changes in voltage that can damage any instruments connected to it.
Electrical panel for manual start-up
-
Ensure that all automatic switches are open in the “OFF” position.
- Insert the key into the ignition and turn it to the start position until the machine starts-up.
- When the engine starts-up, release the key and verify that the dynamo and oil warning lights have gone off.
- Let the unit work for 5 - 10 minutes until the engine warms up.
-
Then turn the switches to the closed “ON” position so as to connect the load.
Turning the generator off
When the generator is to be turned off, the mains switch of the electrical panel must be disconnected before
stopping the machine.
The generator will stop by turning the key in the ignition to the
0
position.
Should the generator be used for a long period of time at full load, it must be left in idle mode for 5 minutes
before switching it off.
Electrical panel for automatic start-up
The generator automatically starts-up when there is a power failure. This occurs via the automatic electrical
panel transfer switch and when the power returns, the unit shuts down (
refer to the automatic control panel
manual
).

Fuel
Do not fill the tank completely
– leave approx. 1 cm below the maximum level to prevent the
fuel from spilling.
