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.
WARNING:
Mixed switch operation is not permitted to the switching outputs of both auxiliary
switches (A and B).
Either AC line voltage from the same phase must be applied to all six outputs of the
dual auxiliary switches, or UL-Class 2 voltage must be applied to all six outputs.
NOTE:
CAUTION:
Do not parallel wire GBB13x or GIB13x actuators with other type of actuator
including GBB/GIB actuators with date codes earlier than 501.
Each wire has the standard symbol printed on it. See Table 2.
