Direction of Damper
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.
Do not wire different types of actuators (such as GBBx or GIBx) in parallel with
the GDE13x or the GLB13x models.
All six outputs of the dual auxiliary switch (A and B) must only be connected to:
Class 2 voltage (UL/CSA).
Separated Extra-Low Voltage (SELV) or Protective Extra Low Voltage
(PELV) (according to HD384-4-41) for installations requiring
conformance. You must use a
All wiring for CE certified actuators must be "Separated Extra Low
Voltage" (SELV) or "Protective Extra Low Voltage" (PELV) per
Use safety-isolating transformers (Class III transformer) per EN61558.
They must be rated for 100% duty cycle.
Over current protection for supply lines is maximum 10A.
If the damper blades turn counterclockwise to open (CCW), reverse the 6 (violet) and
7 (orange) wires at the controller.
