1. The correct type and rating of line input fuse MUST BE
the customers isolator or breaker close to the compressor.
Fast Acting Class J, T or Semiconductor type, Current limiting,
Interrupt Rating 200,000 Amps RMS SYM.
Alternate fuse may be used if the time current characteristics are faster
than fuses recommended in this section.
2. PVC/PVC Type Calculated using the following conditions:
i) PVC insulated cable, armoured, copper conductors.
ii) Cable clipped to a wall, in free air.
iii) Ambient temperature of 40 C (104 F) and relative humidity of 40%.
iv) 20m (65ft) cable run.
v) Volt drop limited to 10% during starting,
running.
vi) Protected by the fuse listed above.
3. Always apply local electrical codes for sizing cables and fusing.
If there are any deviations from the above, or special regulations
apply, the installation must be planned by a competent, quali ed
engineer.
NOTE
All data applies to standard product only.
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.
Line reactors are not recommended. If site speci c conditions indicate
that a line reactor is required, the application should be reviewed by
Ingersoll Rand technical support before installation of the line reactor.
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
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 Modi cation Option is tted 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 xed machinery, which is not intended to be moved during
its operational life (For example, a compressor permanently xed
outside of buildings) and is therefore excluded from the Directive.
This exclusion is on the basis that
part of a factory or plant , and that local Environmental Noise
Regulations will apply to this factory / plant, in place of the directive.
