The MACH-Pro(Web)Com requires power from a Class 2, 24 VAC or 24 VDC, 20 VA power
supply. One or more controllers can be powered from the same source. Ensure that
polarity is the same if multiple controllers share the same power source. Network
protection bulbs will light-up if polarity is crossed.
Do not connect any peripheral devices to the same power source as the MACH-
Pro(Web)Comcontroller.
Use only a Class 2 (UL) or Class III Equipment Safety Isolating Transformer certified to IEC
61558-2-6.
The 24 VAC return/neutral wire must be grounded to the building's Earth ground.
Apply minimum 4.0–5.5 in-lb torque for tightening field wires into terminal blocks. Use 30–
12 AWG wires.
External wiring connected to the controller is to be provided a relief from strain and twisting.
