4.0 INSTALLATION AND CONNECTIONS
4.1
GOODS INSPECTION
Before leaving the factory, the correct mechanical and electrical state of the 28V DC GPU is checked in a
final inspection. As soon as the equipment has arrived check whether any freight damage has occurred
and if necessary, bring this to the attention of the freight operator. In no circumstances put a damaged
converter into service without consulting your Tronair representative first.
4.2
HANDLING
The converter can be rolled into place or moved by means of a forklift or pallet lift truck
IMPORTANT
Moving by crane should only be used in exceptional circumstances using load-
spreading rails above the unit.
Please pay attention to the following handling advice:
•
Equipment should only be transported in an upright position
•
The equipment must not be tilted or turned over
•
Always avoid sharp impacts
•
Where possible, leave the equipment in its original packing when moving it, this provides the best
possible protection against damage
•
When moving the equipment on raised floors, it could be necessary to use a means of load
distribution in order to avoid damage to the floor
4.3
PROTECTION
During installation and cabling it is absolutely essential that the equipment is protected from the ingress of
water, concrete or metal particles, and dust etc.. Protection of the equipment is particularly important
when other trades or construction is taking place in the same vicinity. All inlets and parts of the
equipment not being worked on should be covered, at the least with heavy-duty polyethylene, and
preferably with more substantial packing.
It is also important to ensure that people working overhead do not stand on the equipment or use it as a
convenient platform for other work.
On completion of any work requiring the opening of the equipment doors or panels or removal of cover
plates or gland plates, the unit should be thoroughly vacuumed out and re-packed or protected. Tronair
accepts no liability for any damage to equipment caused by physical mal-treatment or by ingress of
foreign material.
4.4
STORAGE
If it is necessary to store the converter for any length of time then it should be stored in a dry, well-
ventilated room that is free of corrosive materials. Where possible, the original packing should not be
removed during storage.
IMPORTANT
In no circumstances must the converter be stacked, or stored outside.
