Mixed switch operation to the switching outputs of both
dual end switches (5° and 85°) is not permitted.
Either AC line voltage from the same phase must be
applied to all six outputs of the fixed dual end switches,
or UL-Class 2 voltage must be applied to all six
outputs.

Not In Use
Input Signal Inversion
Allows inverting the control input signal
The arrow direction indicates opening or closing (closing or opening)
when operating an actuator with a given control signal.
= Direct acting (Factory setting)
Input signal 2 Vdc ► fail-safe position
= Inverse acting
Input signal 10 Vdc ► fail-safe position
Feedback Signal Inversion
Allows inverting the position feedback output signal
= Direct acting feedback (Factory setting)
Fail-safe position
► Output signal 2 Vdc
= Inverse acting feedback,
Fail-safe position
► Output signal 10 Vdc
Wiring
All wiring must conform to NEC and local codes and regulations.
Use earth ground isolating step-down Class 2 transformers. Do not use
autotransformers.
The maximum rating for a Class 2 step-down transformer is 100 VA.
Determine the supply transformer rating by summing the VA ratings of
all actuators and all other components used. It is recommended that
one transformer power no more than 10 actuators (or 80% of its VA).
Installations requiring
Conformance:
All wiring for 24 Vac/dc actuators must only be safety extra-
low voltage (SELV) or protective extra-low voltage (PELV)
per HD384.
Use safety transformers per EN61558 with double isolation,
designed for 100% duty-cycle for supplying SELV or PELV
circuits.
Over-current protection for supply lines is maximum 10A.
