9.3.7 Outlet sockets (S) - 1-phase
A brief description of all outlet sockets and circuit
breakers provided on the generator is given hereafter:
XS2.....1-phase outlet socket (230 V AC)
Provides phase L1, neutral and earthing.
XS3.....1-phase outlet socket (230 V AC)
Provides phase L1, neutral and earthing.
Q601... Circuit breaker for XS2
Interrupts the power supply to XS2 when a
short-circuit occurs at the load side, or when
the overcurrent protection (16 A) is
activated. When tripped, Q601 interrupts the
three phases towards XS2. It can be reset
after eliminating the problem.
Q602... Circuit breaker for XS3
Interrupts the power supply to XS3 when a
short-circuit occurs at the load side, or when
the overcurrent protection (16 A) is
activated. When tripped, Q602 interrupts the
three phases towards XS3. It can be reset
after eliminating the problem.
9.3.8 IT-relay
The generator is wired for an IT network i.e. no
supply lines of the power supply are directly earthed.
A failure in insulation resulting in a too low insulation
resistance, is detected by the insulation monitoring
relay.
Circuit breaker Q600 does not only
interrupt the power supply towards
X10, but also towards XS2 and XS3.
Make sure to switch on circuit
breakers Q600, Q601 and Q602 after
starting the generator when power is
supplied by means of XS2 or XS3.

Not available for 60 Hz units.
The generator shall not be operated
with other networks (such as TT or
TN). Doing so will cause tripping of
the insulation monitoring relay.
The generator is wired for an IT
network i.e. no supply lines of the
power supply are directly earthed.
A failure in insulation resulting in
too low an insulation resistance, is
detected by the insulation
monitoring relay.
At each start-up and any time a new
load is connected, the insulation
resistance must be verified. Check
for the correct setting of the
insulation monitoring relay. (factory
set at 13 kΩ)
