O
UTPUT TERMINAL BOARD
The output terminal board is situated below the control and
indicator panel.
S2........Emergency stop button
Push the button to stop the generator in case of an emer-
gency. When the button is pressed, it must be unlocked, by
turning it anti-clockwise, before the generator can be re-
started.
X1........3-phase outlet socket (400 V AC)
Provides phases L1, L2 and L3, neutral and earthing.
X2........3-phase outlet socket (400 V AC)
Provides phases L1, L2 and L3, neutral and earthing.
X3........1-phase outlet socket (230 V AC)
Provides phase L3, neutral and earthing.
XE .......Earth terminal
Connected to the earthing of outlet sockets X1 and X2 and to
the earthing of the alternator.
OPERATING INSTRUCTIONS
In your own interest, always strictly observe all rele-
vant safety instructions.
Do not operate the generator in excess of the limita-
tions mentioned in the Technical Specifications.
Local rules concerning the setting up of low voltage
power installations (below 1,000 V) must be respected
when connecting site distribution panels, switch gear
or loads to the generator.
At each start-up and at any time a new load is con-
nected, the earthing of the generator must be verified.
Earthing must be done either by the earthing rod or, if
available, by an existing, suitable earthing installation.
The protective system against excessive contact
voltage is not effective unless a suitable earthing is
made.
The generator is wired for a TN-system to IEC 364-3,
i.e. one point in the power source directly earthed - in
this case the neutral. The exposed conductive parts of
the electric installation must be directly connected to
the functional earth.
If operating the generator in another power system,
e.g. an IT-system, other protective devices required
for these types must be installed. In any case only a
qualified electrician is authorized to remove the
connection between the neutral (N) and earth termi-
nals in the terminal box of the alternator.

NSTALLATION
– Place the generator on a horizontal, even and solid floor.
– Protect the generator against dust and rain if it is operated
outside.
– Check that the engine exhaust is not directed towards
people. If the generator is operated indoors, install an
exhaust pipe of sufficient diameter to duct the engine
exhaust towards the outside. Check for sufficient ven-
tilation so that the cooling air is not recirculated. If
necessary, consult Atlas Copco.
– Leave enough space for operation, inspection and mainte-
nance (at least 1 meter at each side).
– Check that the inner earthing system is in compliance with
the local legislation.
– Install the earthing rod as near as possible to the generator
and measure its diffusion resistance (max. 1 K
Ω
) in order
not to have a contact voltage higher than 25 V at 30 mA
leakage current.
– Check that the cable end of the earthing rod is connected
to the earth terminal.
– Use soft water for the engine cooling system. If low
temperatures are expected (close to 0 °C), the engine
cooling system must be protected (refer to the Engine
instruction book).
– Check the tightness of the bolts and nuts.
