24 Vac – Modulating Control
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 sum of the VA ratings of all actuators and all other components powered by one
transformer must not exceed the rating of the transformer.
•
It is recommended that one transformer power no more than ten actuators.

(according to HD384-4-41) for installations requiring
WARNINGS:
Installations requiring
•
All wiring for CE certified actuators must be "Separated Extra Low Voltage"
(SELV) or "Protective Extra Low Voltage" (PELV) rated per HD384-4-41.
•
Use safety-isolating transformers (Class III transformer) per EN61558.
They must be rated for 100% duty cycle.
•
Overcurrent protection for supply lines is maximum 10A.
