Ingersoll-Rand HXP50-PE, SSR UP6 40, SSR UP6 50PEI HF50-PE, EP50-PE manual Installation / Handling

20 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,

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.
