Page 7: Introduction
This installation and operation manual covers EarthGuard Firmware Revision v1.1. Supported System Components All AERL products have been tested for compatibility with the EarthGuard EG-300 but some third-party products may internally exceed the maximum allowed leakage tolerated by the EarthGuard, causing the device to immediately trigger. -
Page 8: Installation
The EarthGuard should be fixed to a vertical surface using the mounting holes in the chassis flanges. If the device is being used with an AERL CoolMax SRX Solar Charge Controller, the top plate can be removed from the EarthGuard and the device can be mounted seamlessly against the base of the CoolMax. -
Page 9: Wiring Information
Use appropriate Personal Protective Equipment when handling live connections and disconnect all power sources prior to making any wiring configuration changes. EarthGuard EG-300 • 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). -

USER MANUAL EarthGuard – EG-300 Australian Energy Research Labs AER013 – Rev 1.1 21st July 2020 Wiring Diagram Please refer to Figure 1 below for the recommended wiring configuration. CAUTION – Potential Hazard If the DC+ and DC- sense wires are at risk of mechanical damage in their installed location, appropriately rated in-line fusing is highly recommended due to the potential fault currents available from the connected battery bank. -
Page 11: Adjusting The Trip Sensitivity
USER MANUAL EarthGuard – EG-300 Australian Energy Research Labs AER013 – Rev 1.1 21st July 2020 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. -
