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.
 Determine the supply transformer rating by summing total
VA of all actuators used. The maximum rating for Class 2
step-down transformer is 100 VA.
 It is recommended that one transformer power no more
than 10 actuators.
WARNING:
Terminal connection G is 24 Vac HOT,
not ground.
CAUTION:
G0 and G must be properly wired for
correct function and full life of the actuator.
