General Notes
Motor Cable & Connection Header
2.1
CAUTION: Use of extension cables may cause permanent
damage and will void the product warranty.
UniDrive® motors and controls are designed to operate together as
a complete and compatible drive system. Proper care must be
taken to prevent damage to the Automation Controls Group (ACG)
control, motor and connection cable.
UniDrive® motors come with a permanent, built-in power & control
cable having either a 20 inch or a 72 inch cable length for connection
solely to compatible ACG controls. See the specific UniDrive® motor
or PowerCube™ specification sheet for details. Do not attempt to
connect the motor cable to any control other than one
manufactured by Automation Controls Group (ACG).
Do not put tension on the motor cable connection. Tension, cable
strain or stress on the motor cable could deform the pressure
contacts inside the motor connector. This could result in
intermittent motor connections and in extreme cases may bend the
pins on the control board.
The motor connector is designed to be installed on the control and
then remain connected to the control for the life of the motor. Do
not remove the motor connector except in the rare instance of
motor or control replacement. The motor connector must not be
used as a power on/off switch.
If the motor connector must be removed from the control, remove
the connector slowly by carefully lifting while also gently rocking the
connector from side-to-side ("inch-worming") in order to lift the
connector off the control pins a little at a time. Lift the motor
connector straight up by grasping the sides of the motor connector
and avoid using the cable strain relief as a handle to lift the
connector.
Power to the control and motor must be removed by turning off or
removing input power at the source (Lock-out & Tag-out preferred).
Alternately, by disconnecting the +24V DC Power Input Connection
Header (see section 2.2 below) on the control.
connector must not be used as a power on/off switch.
Do not disassemble the motor cable. If the motor cable becomes
damaged obtain a replacement motor.
NOTE: The motor connection cable must be oriented on the
control header pins as shown in the figure below.

+24V DC Power Input Connection Header
CAUTION: Power must be applied with proper polarity to
avoid potentially damaging the controller. Follow the
pinout shown in Table 1 below.
A 2-pin Phoenix PT1.2/2-PVH-3.5 plug is supplied. The SCC-3 operates
off a +22 to +28 Volt DC power supply. The control reads the
configuration switches only when the unit is powering up. Make the
power connection only after all other connections have been made.
NOTE: When adjacent zones are operating from separate
power supplies you should connect their 0VDC grounds.
However, do not connect their positive voltage pins together.
PNP Sensor Connection Header
2.3
CAUTION: If the sensor is mounted on non-conductive
equipment, such as a plastic slide, ground the body of
the sensor to provide a non-destructive discharge path in
the event of a static electric shock.
A 3-pin Phoenix PT1.5/3-PVH-3.5 plug is supplied.
*NOTE: The +VDC signal for pin number 3 is fused with a 0.1
Amp self-resetting fuse. Use of this output for any purpose
that requires more than 0.1 Amps will cause the fuse to
open and temporarily disable this output.

Smart User Input-Output Connection Header
A 7-pin Phoenix PT1.5/7-PVH-3.5 plug is supplied. Function depends
upon the controller's current configuration based on the
configuration switch settings. If the smart I/O is not being used,
leave the connector in place to avoid accidentally shorting the pins.
