MCD 500 Operating Instruction

4 Electrical Installation

4.1.1 Control Wiring

The soft starter can be controlled in three ways:
• using the buttons on the LCP
• via remote inputs
• via a serial communication link
The MCD 500 will always respond to a local start or stop command (via the Hand On and Off buttons on the LCP). Pressing the Auto On button selects
remote control (the MCD 500 will accept commands from the remote inputs). In remote mode, the Auto On LED will be on. In local mode, the Hand On
LED will be on if the MCD 500 is starting or running and the Off LED will be on if the MCD 500 is stopped or stopping.

4.1.2 Control Terminals

Control terminations use 2.5 mm plug-in terminal blocks. Different models require control voltage to different terminals:
CV1 (24 VAC/VDC)
CV2 (110 - 120 VAC)
CV2 (220 - 240 VAC)
NB!
If you are not using a thermistor, do not short terminals 05, 06.
