6.14 Mains Input Cable Specification
The aim of electrical cables is to be a carrier (conductor) for electrical power. The influence of the power source on
the environment, or the influence of the environment on the power source, should be such that neither the proper
functioning of the compressor nor equipment in its environment is adversely affected. Therefore, Danfoss LLC
advises to use some type of shielded cable for the mains input.
When using shielded cable, select a cable with an effective shield. A cable with an aluminum foil will be far less
effective than a specially designed conductive braid. It is best to connect both ends of the cable shield to ground
since the shield is not part of the signal path. Alternatively, non-shielded conductors may be used if they are carried
inside of a code-approved electrical metallic conduit of the flexible or rigid types.
The mains input cable should be CSA, UL, or CE approved, three-wire with a common shield and single ground. The
cable must be rated for 90°C (194°F) minimum at the maximum applicable current. It is recommended that the cable
be double-jacketed, e.g., teck cable type. Refer to Table 6-4 Main Cable Connector Plate Hole Sizes for cable gland
specifications.

NOTE
The plate hole sizes shown in Table 6-4 Main Cable Connector Plate Hole Sizesare standard production sizes for standard compressors
released at the time of this publication. OEMs have the flexibility to change those sizes according to their needs. Please refer to the Spare
Parts Selection Guide for more information on available sizes or contact your Key Account Manager for possible changes. If OEMs are
ordering compressors using the New Type Code configuration the mains plate connector size can be selected at the time of order.
6.15 Idle Power Consumption
