1)
The Specifications for the typical motor current and the power data in
hp and kW are approximate values only; these have been calculated for
operation with induction motors and for a typical power factor
c
s
and motor efficiency. Both approximate values have to be adapted to
the motor that is actually used.
2)
Values at 100% of rated speed and torque; includes drive and input
transformer.
3)
120/240 V AC for NXGII control and 120 V AC internal heat exchanger
in water-cooled systems.
4)
Includes cooling blowers/pumps; largest unit shown. CPT: Control
power transformer.
5)

For dimension drawings please refer to Section 5, pg 5/11.
9)
Drive Weight is based on cell cabinet, transformer cabinet, and coolant
cabinet only.
