INPUT PWR Connector
The MU-1300, MU-2300 and MU-3300 controllers feature a 2-pin 3.5 mm Phoenix connector with screw retention for
providing DC power to the controller. The suggested power supply for the MU-series controllers is a 13.5 VDC 6.6 A
output, suitable for 50° C.
Preparing Captive Wires
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
NOTE: Never pre-tin wires for compression-type connections.
1.
Strip 0.25 inch (6.35mm) of insulation off all wires.
2.
Insert each wire into the appropriate opening on the connector (according to the wiring diagrams and connector
types described in this section).
3.
Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively, as doing so may
strip the threads and damage the connector.
ID Pushbutton
All MU-series controllers feature an ID pushbutton which you can use to reset the default settings on the controller or
restore the controller to its factory firmware image. The Status LED will indicate the action performed by changing
color.
The ID Pushbutton functionality is as follows:
