TORQUE SPECIFICATIONS
All of the screws on the field terminal connections
must be torqued according to the tables to the right.
Two different types of terminal blocks may be used. If
the terminal blocks are beige colored, they are manu-
factured by Siemens and must be tightened per the
first table. If the blocks are gray colored, they are
manufactured by Entrelec or Woertz and must be
tightened per the second table.

Copper conductors are required. Power wiring must be 75
o
C rated. If higher temperature rated wiring is
used, it must be sized based on 75
o
C wire ampacities.
Drive has been tested by UL and is suitable for use on a circuit capable of delivering not more than 40,000
RMS symmetrical amperes, 575 V AC maximum.
1
Input current measured using a 460 V AC , 2500 kVA, 7% impedence transformer. Actual input current will
vary with transformer size.
2
Refer to “Output Drive Current” rating on the plastic cover over the control board for this value.
Values are based on true RMS amps.
3
Isolation transformer sizing is based on 460 V AC input for drives without bypass. Consult Graham for
other input voltages. isolation transformaers must be designed for use with adjustable frequency drives.
