Section 4. Wiring Instructions
4.1. Wiring MGD-100s
Step Wiring MGD-100s
1
Connect a 4-conductor cable (18 AWG recommended) to a
terminal block on the MGD-100 controller (CN1, CN2, etc).
2 Route the cable to an MGD-100.
3
For standard (IP41) MGD-100 housings, remove the lid by:
• turning the cable clamp ½ turn counter clockwise to
loosen the internal nut
• depressing the clip on top of the enclosure to open.
4 Mount the MGD-100. See Section 3 for dimensions.
5
Connect the other end of the cable to the MGD-100 using
terminal block CN1 positions 1,2,3 & 4. (installation should
be such that pin 1 of the MGD-100 controller is connected to
pin 1 of the MGD-100).
6 Close the housing.
7 Repeat above sequence for any/all remaining MGD-100s.
NOT E: Install a 2200 Ohm resistor between i nput pins 2 and 3
on any unused channels. If unused channels do NOT have a
resistor installed a fault will occur.
