3.3 Installation
3.3.1 Indoor installation
If the machine is operated in a closed environment,
make sure that there is enough ventilation to remove
the exhaust gases from the room where the engine is
running; also ensure that the exhaust gases are
discharged at a distance that will not allow them to be
drawn back into the engine. 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 re-circulated.
Place the machine at least at 1m from each wall and
the ceiling and provide suitable openings to allow
sufficient air flow for adequate cooling and good
engine combustion.
3.3.2 Outdoor installation
– Place the light tower on a horizontal, even and
solid floor. Check the levels on top of the light
tower to ensure its level position.
– The light tower should be kept with the doors
closed, in order to avoid the ingress of water and
dust. Dust ingress reduces the lifetime of filters
and may reduce your light tower's performance.
– Check that the engine exhaust is not directed
towards people.
– Locate the rear end of the light tower upwind,
away from contaminated wind streams and walls.
Avoid re-circulation of exhaust air from the
engine. This causes overheating and engine power
decrease.
– 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 a cable of suitable section to connect the PE
terminal to an earth plate that can ensure an earth
resistance suited to the characteristics of the light
tower.
– Check that the cable end of the earth pin is
connected to the earth terminal.
3.4 Connecting the light tower
3.4.1 Precautions for non-linear and
sensitive loads
The most common non-linear loads are thyristor/
rectifier-controlled 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 elevators.
Consult Atlas Copco for measures against the adverse
influence of non-linear loads.
For more information about indoor
installation, consult your local Atlas
Copco dealer.
The light tower 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.
Non-linear loads draw currents with
high contents in harmonics, causing
distortion in the wave form of the
voltage generated by the alternator.
