Devices attached to any Relay connection must be Single Phase and rated for
the same voltage as the input voltage to the product. (e. g. 120VAC MicroTrac
controllers support 120VAC relay attached devices exclusively and 220VAC
MicroTrac controller support 220VAC relay attached devices exclusively.)
Do not apply power until this condition is verified.
Conduit controllers have openings for conduit connections for hard wiring.
