Before the formal operation, suggest do checks as bellow:
1) Confirm all wiring correct and the wire diameter suitable.
2) Confirm module DC working power installed fuse and positive and negative electrode which
connected to starter battery connect correctly.
3) Confirm GPS antenna placed open outdoor, otherwise, location information will not be found or
inaccuracy.
4) Confirm insert SIM card.
5) Confirm POWER indicator turns to green, which means cloud monitoring module connected to the
cloud platform successfully.
6) Confirm module’s ID be added to the register account through cloud sever platform. Ten real time
data can be checked.
7) Any other problems please contact with SmartGen service.

1) AC Input
Controller current input must connect with CT and CT secondary current must be 5mA. Meanwhile,
phase of CT and phase of voltage must be correct. Otherwise, the sample current and the active
power may be incorrect.
Note: ICOM perminal must be connected with controller negtive electrode.
Warning: Transformer secondary side is forbidden to open circuit when with load current.
2) High Voltage Test
Caution: If controller has been installed into control panel, when do High voltage tests, amphenol
connectors of controller must be disconnect to avoid high voltage damage the controller.
