The appropriate installation and use of 75ºC wire is the responsibility of the electrical professional(s) performing the
installation and must be per NEC, local and state regulations as allowed. All of the above recommended minimum
wire sizes are based on all terminal connections being rated at 75ºC minimum temperature rating and copper wire
run lengths of 100 feet or less. Please note that all UL-508A listed control panels are rated for 40ºC ambient
conditions
Please refer to Section 6 of this manual for detailed instructions on the installation, operation and
maintenance of the water cooled heat exchangers.
ELECTRICAL WIRING -
The compressor package is (internally) factory wired for use with the voltage
specified on the order - it is only necessary to connect power supply and ground wires to the provided
wire terminal blocks.
Electrical shock can cause injury or death. Open main disconnect switch, lockout and
tagout before working on control box.
Gardner Denver Guidelines for proper wiring, grounding and feed power conditioning -
This
compressor package is provided with a variable speed drive (VFD) to control compressor motor. The
indicated Gardner Denver guidelines for proper wiring, grounding, and feed power conditioning must be
followed in order to protect the VFD electronics. Failure to do so will void your warranty.
Electrical Wire Sizing
– A certified electrician familiar with National Electric Codes and applicable local
codes shall size the electrical power wires serving the compressor package. Refer to Figure 2-2, for a
summary of maximum package current consumption values.
