INSTALLATION / HANDLING
1. If a circuit breaker is selected it should only be a magnetic trip type,
set above the anticipated starting current of the machine, but below the
maximum prospective fault current for the circuit. The circuit breaker
or fuseable disconnect must be capable of breaking the prospective
fault current at its terminals.
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 104_F (40_C) and relative humidity of 40%.
iv) 65ft (20m) cable run.
v) Volt drop limited to –10% during starting, –5% during normal
running.
vi) Protected by the circuit breaker listed above.
If there are any deviations from the above, or special regulations
apply, the installation must be planned by a competent, qualified
engineer.
NOTE
All data applies to standard product only.

ELECTRICAL DATA

An independent electrical isolator or disconnect should be installed
adjacent to the compressor.
SSR UP6 40, SSR UP6 50PE, SSR UP6 50PEI, HF50–PE, EP50–PE,
HP50–PE, HXP50–PE
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.
The control circuit transformer has different voltage tappings.
Ensure that these are set for the specific applied voltage prior to
starting.
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
Ensure that the motor, blower and dryer fan rotate in the
correct direction as indicated by direction arrows, and on
drawing.
