The GDE131.1N has two sets of identical contacts as shown in Figure 20.
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 the total VA of all
actuators used. It is recommended that one transformer power no more than 12
actuators.
Direction of Damper Rotation
To change the direction of rotation of the GDE131.1N, switch the Y1 and Y2 wires at
the controller.
NOTE:
This rotation will affect all actuators in the daisy chain configuration.
