2.4.3
Output terminal board
The cubicle provides a terminal board for easier
connection of cables. It is situated below the control
and indicator panel, hidden behind the control panel
door and behind a small transparent door.
Q600 ... Main circuit breaker
Interrupts the power supply to X10 when a
short-circuit occurs at the load side, when the
earth leak detector (30 mA) or the
overcurrent protection (QES 60: 100 A,
QES 80: 125 A, QES 100: 160 A, QES 120:
200 A, QES 150: 250 A, QES 200: 400 A)
is
activated, or when the shunt trip is
energized. It must be reset manually after
eliminating the problem.
X3/X4.. Customer terminals
X10 ..... Main power supply (400 V AC)
Terminals L1, L2, L3, N (= neutral) and PE
(= earthing), hidden behind the control panel
door and behind a small transparent door.
FS1 ..... Earth leak detector
Detects and indicates an earth fault current
and activates the main circuit breaker Q600.
The detection level can be set at 0.03 A fixed
with instantaneous trip, but can also be
adjusted between 0.1 A and 30 A with time
delayed (0 - 4.5 sec) trip. FS1 has to be reset
manually after eliminating the problem
(Reset button) and has to be tested monthly
(by pushing the Test button).
2.4.4
Earth leakage relay
An earth leakage relay provides protection in case of
an earth leak current.
The functionality of the earth leakage relay should be
tested daily to guarantee safe use of the generator set.
