Electrical Wire Routing
– Routing of the electrical power wires into the electrical hardware enclosure is
best done through its roof area.
Line Reactor –
A line reactor provides conditioning of the electrical power supply to the compressor
package by attenuating noise and fluctuations. It shall be required in your particular application if any of
the following conditions exist:
·
Transformer KVA is greater than recommended
– see Figure 2-4, page 23.
·
Line has switched Power Factor correction capacitors.
·
Existing line reactor not properly sized
– see Figure 2-4, page 23.
·
Other large loads on the same power feed as the compressor.

GROUNDING –
Equipment must be properly grounded in accordance with the National Electrical Code
and/or applicable local codes.
Failure to properly ground the compressor package could result in injury or
death. Install ground wiring in accordance with the National Electrical Code
and any applicable local codes.
