ELECTRICAL DATA
An independent electrical isolator or disconnect should be installed
adjacent to the compressor.
Feeder cables/wires should be sized by the customer/electrical
contractor to ensure that the circuit is balanced and not overloaded by
other electrical equipment. The length of wiring from a suitable
electrical feed point is critical as voltage drops may impair the
performance of the compressor.
Feeder cables / wires connections to isolator or disconnect should
be tight and clean.
The applied voltage must be compatible with the motor and
compressor data plate ratings.
Do not use a buck and boost transformer.
CAUTION
Never test the insulation resistance of any part of the machines
electrical circuits, including the motor without completely
disconnecting the electronic controller (where fitted).
CAUTION
Do not verify cooling simply by air flow direction, but ensure
that the fan rotates in the correct direction as indicated by
direction arrows
NOTE
If the compressor is installed for 208V 60hz or 380V 60hz
applications, the wiring at the primary of the transformer needs to
be changed during installation.
OUTDOOR MODIFICATION OPTION
EU Directive 2000/14/EC. Noise Emission By Equipment For Use
Outdoors
The standard compressor packages are not suitable for use
outdoors. If the Outdoor Modification Option is fitted to a machine
which will be operated within the EU the machine is not intended to be
used as hire equipment or moved from place to place. It must be
installed as fixed machinery, which is not intended to be moved during
its operational life (For example, a compressor permanently fixed
outside of buildings) and is therefore excluded from the Directive.
This exclusion is on the basis that the machine forms a permanent
part of a factory or plant , and that local Environmental Noise
Regulations will apply to this factory / plant, in place of the directive.
