For use with Surge Guard* Hardwire units, the optional Remote Power Monitor LCD Display is connected to a
Surge Guard unit via an RJ12 (6 pin) connector cable and remotely monitors your electrical power anywhere
inside your RV.
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.
The 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.
Features and information displayed includes
the following:
• Main Screen: The Main Screen of the Display
is used to show a continuous status of the RV’s
electrical power. These include: incoming line
voltages and currents (Amps) being used by the RV;
reverse polarity state, which is a faulty shore power
condition; delay state, which is a waiting state that
the Surge Guard device goes into when it is powered
up or when there is a fault with shore power. The
display will revert back to the Main Screen by default
if it is left in any other screen for more than 3 minutes.
• L1/L2 Volt and Current Screens: Displays
Line 1/2 voltage or current. This allows you to view
the voltage or current when there is a fault condition
being displayed on the Main Screen.
• Faults Screen: Allows you to view a history of up
to 50 faults which have been logged by the hardwire
unit. Each fault that has been logged contains the
fault, the voltages and currents at the time of the
fault, and the time and date when it occurred.
• Joystick Lever: to navigate through screens and
set the time and date.

INSTALLATION & OPERATING
INSTRUCTIONS
Model 40300
Optional Hardwire Remote Power Monitor LCD Display
with Navigation

1. Determine a convenient location where the remote display can
be viewed. The display provides a continuous visual indication of
source voltages, load currents, and fault diagnostics. The RJ12 (6
pin) connector cable allows for installation virtually anywhere inside
the RV. It may also be installed in the same location as the Surge
Guard* unit. Mounting is not necessary. Leave enough cable length
for accessibility. Balance of cable can be bundled with a plastic tie
wrap. Should a remote location be desired, route cable through the
coach as needed. (Cable ends and remote display must be located
in a dry interior location away from inclement weather and moisture.)
2. Suggested mounting procedure.
A. Remove cover plate. (Do not allow foreign matter to fall into
open box).
B. Using the open box as a template, mark outline on mounting
surface.
C. Allow room for connector cable.
D. Position box, with cable installed, and secure with mounting
screws (not supplied).
E. Attach cover plate.
3. Connect Remote Display to Surge Guard device using RJ12 (6
pin) connector cable. The Remote Display can be connected to the
Surge Guard device before or after the Surge Guard device has
been powered up.

OPERATING INSTRUCTIONS
Screen Navigation
Using the Button/Lever
There are several information
screens associated with the
Remote Display which can be selected via the lever on the front of the
unit. Pushing the lever to the RIGHT repeatedly will access the screens
in the following order. Pushing the lever to the LEFT accesses the
screens in the reverse order.
On the 30A Surge Guard device, the Remote Display will not show the L2
VOLT or the L2 CURR screens, as they are not applicable.
When VIEW FAULTS screen is displayed, pushing down on the lever
accesses a log of faults which have been stored by the Surge Guard unit.
Viewing the fault log data will be explained in more detail below.
Display for Normal Operation
During normal operation, the Remote Display screen reads the status of
the RV electrical power, showing continuous voltages and currents for
power Lines 1 and 2 coming into the RV on the main screen.
Display During Fault Conditions
If there are any faults or problems with your electrical power, the Remote
Display will show the particular faults on the LCD screen with a 3 second
interval between each item. The faults displayed can be any combination
of codes, SEE FAULT CODE INDICATION.
Display During Delay State
When the Surge Guard unit is powered up, the Remote Display will
display "Delay" and the elapsed time in seconds until it reaches 128
seconds. After the delay is completed, if shore power is good the Surge
Guard unit will connect power to the RV, and the unit will go to the normal
operating screen showing voltages and currents as described above.
L1 VOLT | L2 VOLT Screens
These screens are useful for viewing the line voltages when the Main
Screen is in Delay or when L1 or L2 have a fault (line voltage that is too
low or too high). The Main Screen will display line voltage between 102

and 132 volts; otherwise it will show that the line has a
fault. The L1 VOLT and L2 VOLT screens however display
a greater range, from 90 to140Volts. The L2 VOLT screen
is only shown when using a 50Amp Surge Guard.

is only shown when using a 50Amp Surge Guard
device.

VIEW FAULTS Screen
This allows you to view the faults recorded when the Surge Guard
detects a fault with electrical power. To view, momentarily push the front
lever DOWN or In. The screen will display Fault 1, which is the most
recent fault that occurred and was detected by the Surge Guard device.
To see the next fault, push lever right, showing Fault 2. Keep pushing the
lever right to see up to 16 faults. Pushing the lever left goes backwards
through the faults.
To exit the fault screens, push the lever DOWN/IN momentarily, returning
to VIEW FAULTS screen from which you can navigate as previously
described.
Please read these instructions carefully.
