Optional Hardwire Remote Power Monitor
LCD Display w/ Navigation
For use with Surge Guard Hardwire units, the optional Remote Power Monitor LCD Display is connected to a
Surge Guard unit via a RJ12 (6 pin) connector cable and conveniently monitors your electrical power anywhere
inside your RV remotely from the Surge Guard’s location.
This display allows you to see more detailed information such as voltages for Line 1 and Line 2 (typically 110-
120VAC), current draws, and status/conditions of the Surge Guard Hardwire unit. Electrical faults such as Low
Voltage or an Open Ground connection that cause the Surge Guard Hardwire to shut off power are shown on
the remote display, allowing you to retrieve via the joystick a log of the fault conditions kept by the Surge Guard
pf electrical power at your location.
The 40300 Remote Display is a helpful diagnostic tool that allows you to comprehend and correct problems
with your RV's power. The display also features an up/down navigation button/lever allowing navigation through
various informational screens.
