The controller is a thyristor-type power solid state relay designed to control a 3-phase asynchronous motor in two directions.
There are two control signals and an internal logic that permits selection of only one direction at a time.
A green LED indicates forward; a red LED indicates reverse.
The power thyristors are protected against excessive voltage fluctuation by varistors and RC snubbers incorporated in the module.
It is advisable to install three high-speed fuses between the 3-phase line and the controller.
WARNING: The GI models must be used in conjunction with an appropriate heatsink (Accessory). Installation must precisely observe the warnings contained in the installation notes.
