3 Installation and connection
3.1
Lifting
The lifting eye, to lift the light tower by means of a hoist, is integrated in the bodywork and easily accessible from the outside.
When lifting the light tower, the hoist has to be placed in such a way that the light tower, which must be placed level, will be lifted vertically.
To be able to lift the light tower by means of a forklift, forklift slots are provided in the frame at the left and right side of the unit.
3.2
Parking and towing
The operator is expected to apply all relevant safety precautions,
including those mentioned on page 9
to page 14 of this booklet.
3.2.1
Unhooking the light tower
1. Secure the support leg/jockey wheel (1) to support the light tower in a level position.
2. Adjust the height of the support leg/jockey wheel using the handle (2).
2
Lifting acceleration and deceleration must be kept within safe limits (max.
2 g).
Helicopter lifting is not allowed.

To release the light tower from the towing vehicle, carefully follow the procedure below:
5. Uncouple the trailer from the towing vehicle.
Release the locking lever of the towbar coupler
(2), if applicable.
6. Proceed with positioning, to set up the light tower.
To reconnect the light tower to the towing vehicle, proceed as above but in the reverse order (see also
“Towing” on page 24).
3.2.2
Positioning the light tower
Follow the steps below to position the light tower:
1. Ensure that the handbrake is engaged, if available, and make sure that the mast is down.
2. For the two front stabilizers; release the locking pin of the stabilizer (2) by lifting it up and pull the supporting foot (3) at the maximum extension of the stabilizer (4).

1. Engage the handbrake (1), if provided.
2. Disconnect the cable plug for the trailer lights.
3. Adjust the height of the support leg/jockey wheel to level the light tower and to support its weight.
4. Disconnect the safety wire from the towing vehicle.

3.2.3
Positioning for transport
1. Make sure the mast is lowered completely and
turned 90° (1). See also “Lowering the mast” on page 31.

For more detailed installation instructions, see also
“Installation” on page 25.
2. Make sure that the jockey wheel (if available) is safely fastened by its own locking lever to ensure that the light tower is still stable once the stabilizing feet are removed.

3.2.4
Towing
Before commencing towing, ensure you follow the procedure below:
1. Check that the coupler (1) of the undercarriage of the light tower is safely coupled to the towing hook of the towing vehicle.
2
3
4. Use the handle at the top of each foot to retract the
4 feet and retract the front stabilizers and ensure their locking pins following the reverse order of
the procedure described in “Positioning the light tower” on page 22.
Once all the above operations are complete, you will have returned the light tower to the same state as it was before the positioning procedure (see figure above). At this point the light tower is correctly arranged for transport.
1
2. Connect the cabling plug to the towing vehicle so that the rear lights of the light tower work
(indicators, lights, brake lights).
3. Check that the pressure and condition of the tires are suitable for the road and the climatic conditions.
4. Release the handbrake (2), if provided.
Do not proceed with towing if you notice any broken or faulty parts.
Drive carefully according to the road and climatic conditions.
Keep in mind that for the low speed off-road non-homologated trailer, the maximum speed is 20 Km/h!

3.2.5
Transportation and positioning of the light tower onto vehicles
As well as the ability to be towed, the light tower can also be easily lifted and moved to difficult areas thanks to its central lifting eye and fork lift holes in its frame. All that is needed is a fork lift truck or a mechanical arm.
The fork lift holes and the lifting eye can also be used to place the light tower onto trucks for road transportation.
If the light towers are carried on trucks or similar vehicles:
1. Ensure that the machine is stable and secure.
2. Check that the light tower is placed perfectly horizontally (check the levels on top of the unit).
3. To ensure stability, use the fork lift slots (1) and lifting eye (2) to fix the light tower to the transport vehicle.
4. Use straps or other means of anchoring, provided that these do not affect the machine's safe transportation and integrity.
5. It is recommended that the machine is covered by a tarpaulin to protect it against bad weather conditions if it is transported on an open truck.

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.
For more information about indoor installation, consult your local Atlas
Copco dealer.

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 PARCOOL EG for the engine cooling system.
– 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.
The light tower is wired for a TNsystem 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.
3.4
Connecting the light tower
3.4.1
Precautions for non-linear and sensitive loads
Non-linear loads draw currents with high contents in harmonics, causing distortion in the wave form of the voltage generated by the alternator.
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 singlephase circuits generate high 3rd harmonics and risk for excessive neutral current.
Loads most sensitive to voltage distortion include incandescent lamps, discharge lamps, computers, Xray equipment, audio amplifiers and elevators.
Consult Atlas Copco for measures against the adverse influence of non-linear loads.
