Ground Fault Detection
The CoolMax SRX features industry-first onboard PV and Battery system ground fault detection, with all connected
electrical poles checked for insulation degradation during the device’s start-up routine.
The device chassis
must
be connected to the same earth as the PV array for the ground fault detection to function. The
chassis earth point is located inside the access cover and indicated with the symbol demonstrated below.

Chassis Earth Point
IMPORTANT
The system earth configuration (
Ground Fault Mode
) must be adjusted in the AERL Link
software for use with functionally earthed systems otherwise an earth fault will be
detected on the earthed pole.
