EarthGuard – EG-300

Adjusting the Trip Sensitivity

The EarthGuard device currently has two trip sensitivity levels, each tailored for the respective supported

battery voltages (48V & 120V).

By default, the EG-300's are set to 48V, but this can be adjusted to 120V by removing the Jumper

Connection located on the central two pins of the CON2 header while the device is powered down.

Alarm Indication Relay

The EarthGuard features a dry contact signal relay for use with the CoolMax SRX and other external

devices (such as the Victron Venus GX) in order to alert the appropriate personal to the presence of a fault

if the device is installed in a remote location where the audible buzzer will not be heard.

This alarm relay will Open when the device either loses power or an earth fault has been detected.

When the system is All Clear, the relay contact will be Closed.

The Relay Terminal (J5) is located on the top right-hand corner of the PCB and is visible with the access

cover removed.
