Output terminal board
The cubicle provides a terminal board for easier
connection of cables. It is situated below the control and
indicator panel.
S2..... Emergency stop button
Push the button to stop the generator in case of an
emergency. When the button is pressed, it must be
unlocked, by turning it anti-clockwise, before the
generator can be restarted. The emergency stop
button can be secured in the locked position with
the key, to avoid unauthorized use.
Q1.1 . Main circuit breaker
Interrupts the power supply X1 when a short-
circuit occurs at the load side, or when the
overcurrent (QAS 250: 400 A/ QAS 330: 470 A)
protection is activated. When activated, Q1.1
interrupts the three phases towards X1. It must be
reset manually after eliminating the problem.
X1 .... Main power supply
Terminals L1, L2, L3, N (= neutral) and PE (=
earthing), behind a small transparent door.
Battery switch
The battery switch is situated inside the sound-insulated
bodywork. It allows to open or to close the electrical
connection between the battery and the engine circuits.
Spillage free frame
A spillage free frame with forklift slots allows the
customer to transport the generator easily with a forklift.
It avoids accidental spilling of engine fluids.
Position O on switch S13 will only be
used in conjunction with an external
earth fault protection unit (e.g.
integrated in a distribution board) or
when the generator is used in parallel.
The earth fault protection on the single
phase outlet socket is not affected by the
switch S13.
If S13 is in position O, proper earthing is
of the utmost importance for the safety
of the user. Eliminating any earth fault
protection can lead to serious injury or
even death for anybody touching the
unit or the load.
Never turn the battery switch to OFF
during operation.
