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 2-3, for a summary of
maximum package current consumption values.

The NEC requires that wire sizes be determined by using the appropriate multiplier for the conductor temperature rating
at ambient temperatures other than 30º C and then selecting the wire that has sufficient ampacity, after correction, to
meet the load requirements shown in the "NEC Package Amps @ 30ºC" column above. Wire ampacity is to be corrected,
not "Package Amps”. Additional correction multipliers apply based on more than three conductors in one conduit. The
appropriate installation and use of 75ºC and 90ºC 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.
