If the drive exhibits excessive losses or reactive power, the NXG I/O digital output (M1-DOUT)
is opened and the dedicated NXG I/O digital output (IDO-15) is closed as a one-shot pulse
that latches the LFR coil. This action causes the Normally Closed (N.C.) LFR contact to OPEN.
MV IP Breaker Enable
The MV IP Breaker Enable contact
the drive input medium voltage up on the rare event of a secondary circuit fault.
● Contacts close = Permissive to close breaker
● Contacts open = Trip breaker
Failure to integrate this contact as specified may cause death, serious personal injury and
damage to the drive.
Terminal Blocks
The drive uses 8 mm, 600 V terminal blocks from the auxiliary input three-phase voltage (used
primarily for blower control). These terminals accept #8 - #22 AWG wire.
The single-phase control terminal blocks accept #12 - #22 AWG wire.
Auxiliary Voltage Transformer
The auxiliary voltage transformer steps customer-supplied three-phase auxiliary voltage down
to a single-phase 220 V for use with an NXG controller.
Note
Selection of Auxiliary and Control Voltage Supply
When Auxiliary and Control Voltage Supply Option is selected, control power will be supplied
by the customer's power source and auxiliary transformer will be installed.
