Wiring Information
The EarthGuard can be installed on to either a 48V or 120V Nominal Battery Bus in systems with a
connected PV array not exceeding 300V DC.
Wire and Disconnect Sizing
IMPORTANT
•
Use appropriate Personal Protective Equipment when handling live connections and
disconnect all power sources prior to making any wiring configuration changes.

•
The 5V Input (USB-C) and fault monitoring lines are internally fused. The 12V input is not fused
and requires an appropriately sized disconnect when not being powered from the CoolMax SRX
12V line (which is fused internally on the SRX side).
•
A jumper connection allows for the choice between 5V and 12V power. The EarthGuard ships
with the jumper located on JP2 for 5V (USB-C) from factory and must be moved to JP1 to power
the device from a 12V source.

Wiring Compartment
CAUTION – Hazard
All EarthGuard wiring must enter the unit through the cable glands in the base plate or
through the top of the enclosure with the top plate removed when being installed in an
integrated configuration with a CoolMax SRX charge controller.
Under absolutely no circumstances should holes be drilled anywhere into the unit to
make other cable entry points. Doing so can cause metal swarf or fillings to enter the
internal electronics and damage the unit once powered up.
To install cabling and configure the device, the 4 x M4 CSK Phillips Screws holding the lid in place
must be removed. When removing the lid, gently disconnect the 10-way cable from the circuit board and
re-fit the cable prior to powering up the device.
IMPORTANT
•
DO NOT remove the lower 2 x M4 CSK Screws from the USB-C panel as this may
cause alignment issues with the USB connection port.
