MP-C-15A Screw Terminals

MP-C-15A has 15 I/O points and the controller is equipped with six pluggable terminal blocks and one fixed terminal block.

Danger Danger

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Disconnect the power supply and other high voltage equipment before wiring.

Failure to follow these instructions will result in death or serious injury.

Recommended screw tightening torque: 0.56 Nm (5 lbf.in)

The terminal blocks are used as follows:

  • One 3-position pluggable terminal block for the power input

  • Three 3-position pluggable terminal blocks for the six triac outputs

  • One 2-position fixed terminal block for the high power relay output

  • Two 6-position pluggable terminal blocks for the eight universal inputs/outputs of type Ub
