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.
Q600 ...Main circuit breaker
Interrupts the power supply to X10 when a
short-circuit occurs at the load side, or when
the earth leak detector (30 mA) or the
overcurrent protection
(QES 9-11: 16 A,
QES 14-16: 20 A, QES 20-25: 32 A, QES 30-
40: 40 A, QES 40-50: 63A) is activated or
when the shunt trip is energized. It must be
reset manually after eliminating the
problem.
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).
