Wiring Multiple MPM100 Power Modulators into a System
When wiring multiple MPM100 modules to a MC110A control unit, connect the orange and blue
control wires together in parallel, as shown in the diagram below. You can connect up to twelve
power modulators to a single MC110A control unit. Each power modulator will have its own
heating device circuit wiring.
Wiring MPM100 Power Modulator
Ensure power is removed from the power distribution panel before wiring in the heating
device feed circuit.
Ensure the power modulator (MPM100) and heating device supply circuits are properly grounded.
Always remove power from the MicroZone modules and controlled devices before
removing any MicroZone module covers.
Note that line voltages are still present when STANDBY is selected on units wired
for 240V operation.
