6.3 INSTALLATION
The variable speed AC drive has been properly
mounted, adjusted, and tested prior to shipment of
the compressor package. Inspect the unit to ensure
it was not damaged during shipment. The package
provides a terminal block for connection of three-
phase power and ground. Refer to the package
wiring diagram for specific connection information.
All internal wiring to the drive and motors has been
provided by the factory, in accordance with the
drive's requirements. Do not alter factory wiring. To
ensure proper wiring to the package, use the
following guidelines:
• Use heat-resistant copper cables only, +75°C or
higher.
• The minimum input line cable and line fuses must
be sized in accordance with the rated input current
of the unit. See Table 6-1 and 6-2.
• Consistent with UL listing requirements, for maxi-
mum protection of the variable speed drive, use UL
recognized fuses, type RK, suitable for circuits
delivering fault currents up to 100,000A.
