NOTE:
Outputs of controller are divided into passive output and active output. If need to expand the relays, please
add freewheel diode to both ends of expand relay’s coils (when coils of relay have DC current) in order to prevent
disturbance to controller or others equipment.
3)
AC Input
NOTE:
Current input of controller must be connected to outside current transformer. And the current transformer’s
secondary side current must be 5A. At the same time, the phases of current transformer and input voltage must be
correct. Otherwise, the current of collecting and active power maybe not correct.
WARNING!
When there is load current, transformer’s secondary side is prohibited to open circuit.
4)
Withstand Voltage Test
CAUTION!
When controller has been installed in control panel, if need the high voltage test, please disconnect
controller’s all terminal connections, in order to prevent high voltage into controller and damage it.
