FAQ
After power‑up, adjust the alarm according to the isolation transformer capacity:
10kVA → 45A
8kVA → 35A
6.3kVA → 28A
3.15kVA → 14A
Set via the device menu or through Modbus communication.
“FK” indicates that the FE/KE terminals are not properly connected to the ground busbar. Please check the lower terminal wiring.
Yes, it supports Modbus‑RTU over RS485, allowing easy integration with SCADA, BMS, or other central monitoring systems.
