5.2 Conduit Models (Wiring High Voltage)

Conduit controllers have openings for conduit connections for hard wiring. (See Fig.
4) for input and output power connections. Use only 18 AWG (1,2 mm²) stranded wire
for conduit power and load connections. Supply (input) power is connected via PL5
located on the relay board (Fig. 4). The top part of this terminal block is removable to
allow for easy access to the connector's three (3) screws.
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.
Make sure that all conduit connections are water tight.
