Wiring Requirements Control Leads

The control leads may be connected to a Class 2 circuit if routed separately from Class 1

circuit wiring. Refer to Figure-9.

Refer to Table-4 for the maximum wire run of the control leads.

Caution:

• Use three-conductor, twisted, shielded wire when it becomes necessary to install the

control leads in the same conduit with power wiring or when RFI/EMI generating

devices are near.

• Do not connect the shield or conduit to earth ground.

Table-4 Control Wiring Data.

Power Leads

The low voltage (24 Vac) power leads may be connected to a Class 2 circuit if routed

separately from Class 1 circuit wiring. Refer to Figure-9. Line voltage power leads must be

connected to a Class 1 circuit.

Refer to Table-5 for maximum length of run for given wire size(s). To determine the

allowable maximum power lead run for multiple actuator wiring, divide the maximum run

shown in Table-5 by the number of actuators on the run.
