Control Board
•
The control circuit is designed as an ELV (Extra Low Voltage) circuit, which is basically insulated from the power
circuit. The drive controller cannot be touched after power-on.
•
If the control circuit is connected to an external device with a port that is accessible during power-up (SELV
circuit), be sure to add a level of additional insulation protection isolation to ensure that the original SELV voltage
level of the external device is not changed.
•
It is forbidden to connect the control terminal other than the relay terminal to the AC 220V voltage signal.
