Check the sockets for mechanical damage and thermal overloads
Check the circuit breakers for damage to seals, and measuring instruments for
mechanical integrity

2.
Electrical checks:
Once a month, or at each commissioning, check the following:
the earthing connection for perfect condition
Every 500 operating hours but no less than once per year, check the following:
Check the brushes and the accumulator for wear, and the measuring
instruments mounted on the electrical control panel for correct operation.
Check the switch boxes for possible damage caused by condensation.
Electrical safety per DIN VDE 0701 and DIN VDE 0702
NOTES ON ACCESS TO THE SWITCH
The magnetic cut-out can be accessed for three purposes:
- if a device or a series of devices has been connected and they need higher current
than the switch's rated current
- if a short circuit occurs
In the first case, it is sufficient to reduce the load and then restart the generator,
whereas in the second case, the cause of the short-circuit must be found and
rectified.
