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).

WARNINGS:
Installations requiring Conformance:
• Except for the auxiliary switches (See Warning above) all wiring for actuators must 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.
CAUTION:
Do not parallel MF41-6153 actuators with any other type of actuator.
