– Place the generator on a horizontal, even and solid floor.
– 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 ventilation so that the cooling air is not recirculated. If
necessary, consult Atlas Copco.
– Leave enough space for operation, inspection and maintenance (at
least 1 meter at each side).
– Check that the inner earthing system is in compliance with the local
legislation.
– Use coolant for the engine cooling system. Refer to the Engine in-
struction book for the proper coolant mixture.
– Check the tightness of the bolts and nuts.

The most common non-linear, 3-phase loads are thyristor/rectifier-con-
trolled loads, such as convertors supplying voltage to variable speed
motors, uninterruptable power supplies and Telecom supplies. Gas-
discharge lighting arranged in single-phase circuits generate high 3rd
harmonics and risk for excessive neutral current.
Loads most sensitive to voltage distortion include incandescent lamps,
discharge lamps, computers, X-ray equipment, audio amplifiers and el-
evators.
Consult Atlas Copco for measures against the adverse influence of
non-linear loads.

The cable connected to the terminal board of the generator must be se-
lected in accordance with local legislation. The type of cable, its rated
voltage and current carrying capacity are determined by installation
conditions, stress and ambient temperature. For flexible wiring, rub-
ber-sheathed, flexible core conductors must be used.

If outlet sockets are required, they must be mounted on a site distribu-
tion panel supplied from the terminal board of the generator and in
compliance with local regulations for power installations on building
sites.
