Installation
Install the Motor Wiring
Motor Connections – Bypass Configurations
Connect the motor cables to the motor overload relay output terminals; see the
figures below. The motor grounding conductor can be connected to the ground lug
near the motor overload relay.
Install the Control Wiring (Supplement to ACQ550-U1 User’s Manual)
Connect control wiring to the terminal block 1TB located on the back panel toward
the bottom of the enclosure and terminal block x1 inside the drive.
Control Wiring
The control wiring includes connections to an analog speed command signal and
start/stop relay contact for controlling the drive in the AUTO mode. There may also
be connections to external run enable interlock contacts and a connection from the
Motor Run contact to an external status indicating circuit.
Wiring Practices
The external control wiring must not be run in the same conduit or raceway with any
high power wiring. The external speed reference signal must be wired using a
shielded, twisted pair cable. The shield connection must be terminated at the ground
terminal provided (x1:3). The other end of the shield should be cut and taped back at
the signal source.
