Wiring Requirements Control and Power Leads
Remove blue plastic thread protectors before installing conduit fittings. See Figure-1 through
Figure 8 for typical wiring applications and Table-3 for maximum wire lengths.
Caution: The 24 Vac model contains a half-wave rectifier power supply and must not be
powered by transformers used to power other devices utilizing non-isolated full-wave
rectifier power supplies. Refer to EN-206 Guidelines for Powering Multiple Full-Wave and
Half-Wave Rectifier Devices from a Common Transformer, F-26363, for further information.
Note: Class 2 control and power lead wiring must be routed separately from line voltage
wiring and any other non-class 2 circuits.
