MODEL 34850 PORTABLE www.SurgeGuard.com MODEL 34830 PORTABLE INSTALLATION & OPERATING INSTRUCTIONS INPUT POWER CORDS OVER/UNDER VOLTAGE PROTECTION Should voltage drop below 102V or rise above 132V for more than 8 seconds, power to RV is turned off. SEE TIME DELAY INDICATOR The green LED indicates power to RV when illuminated. TIME DELAY INDICATOR POWER ON CAUTION WHEN FLASHING SURGE (No Protection When Lit) SURGE GUARD RV Power Protection SURGE FAILURE MODEL 34850 120/240V, 50 Amp 3850 Joules of Surge Protection POWER PROTECTION 561-00967A www.SurgeGuard.com If the red “SURGE” indicator LED is on, it means that the built-in surge protection has been sacrificed to protect your equipment and is no longer functioning properly. Other features will still function, but the unit is recommended to be replaced. CAUTION LIGHT POLARITY PROTECTION Indicates possible mis-wiring or current to ground condition present. (Will prevent power on 50 amp unit only.) The LCD screen will also indicate REVERSE POLARITY. POWER ON CAUTION WHEN FLASHING SURGE (No Protection When Lit) SURGE GUARD RV Power Protection MODEL 34830 120V, 30 Amp 2450 Joules of Surge Protection POWER PROTECTION www.SurgeGuard.com 561-00966A When unit is plugged in, the red caution LED is flashing indicating delay. The LCD at the same will count up to 128 seconds. When the delay expires, the red caution LED will stop flashing and power will be applied to the RV. Time delay will also be applied to reset once power is restored to a safe range following the 128 second delay. This allows head pressure to bleed off the A/C Compressor. 3 MODE SURGE PROTECTION Protects the RV's sensitive electronic systems and appliances from potentially damaging power surge events without power interruptions to the RV.

Plug the Surge Guard 34830/34850 into an approved RV receptacle and plug the RV power cord into the Surge Guard. 2. Verify the delay indicator is flashing, the LCD is counting. The LCD will read between 102V and 132V. 3. Once caution light stops flashing (this takes 128 seconds), verify RV power is on. NOTE: USING WITH POWER CORD ADAPTERS Purchased power cord adapters will work in most cases with Surge Guard but TRC does not recommend using them for full load applications due to the possibility of over-heating. Be advised that power cord adapters have been known to cause fires when Amps (electrical current) Ratings are exceeded. Should you decide to use an adapter, our recommendation is to check on the power cord from time to time to make sure it is not overheating. TROUBLESHOOTING SYMPTOM Caution light is flashing CAUSE There is a fault. Read LCD for information. SOLUTION For reverse polarity or voltage on ground, move RV to new electrical source. LCD reads less than 1. Only partial 1. Move to a new 102V on first line or power at 50 source L1, L2 Low on either Amp source. 2. Use inverter line. 2. No power at or generator source power When first plugging High or low voltage Change site or use into pedestal power, is present at source. inverter or generator caution light flashes power momentarily, then goes out. LCD DISPLAY INDICATORS REPLACE SURGE Surge Expended OPEN GROUND Open Ground REVERSE POLARITY Any line wired to neutral L1 High 118V 42A 115V 32A L2 High Voltage > 132 L1 Low 118V 42A L1 High L2 Low Voltage < 102 NEUTRIP CUR=65A Current > 130% CUR HIGH Current > 125% PLUG OVERHEAT Temperature > 200ºF Display for Normal Operation During normal operation, the Surge Guard's LCD screen alternates between two displays, a main screen showing voltages and currents for power Lines 1 and 2 coming into the RV; and a secondary screen showing whether power to the RV is ON or OFF, with voltage for Line 1 coming into the RV. The main screen for Model 34850 (50Amp) will show the voltages and currents for Lines 1 and 2, whereas Model 34830 will only show Line 1 since there is no Line 2 for that Model. There are two rows or text lines on the LCD screen. The top row for the main screen shows information for Line 1 in the following format: 120V 50A. This means that the voltage on power Line 1 coming into the RV is at 120 volts and the RV is drawing 50 amps of current on Line 1. The bottom row of the main screen for 34850 shows voltage and current for Line 2. Model 34830 Model 34850 120V 25A 120V 25A Main Screen 120V 30A RV STATUS ON/OFF L1 120V Secondary Screen RV STATUS ON/OFF L1 120V The top row of the secondary screen for both models shows RV ON or RV OFF, and the bottom row shows the voltage on power Line 1 as L1=120V. If the power coming into the RV is less than 102 volts on either Line 1 or 2, then the main screen will show L1 Low or L2 Low, in place of the voltage or current. If the power coming in is greater than 132 volts, then the main screen will show L1 High or L2 High. Display During Fault Conditions Delay When the Surge Guard is powered up, the LCD 011 Sec screen will display "Delay" and the elapsed time in seconds until it reaches 128 seconds. After the delay is completed, the unit will go to the Normal Operating screen showing voltages and currents as described above. If there is a fault condition during normal operation such as high or low voltage, the unit will display that L1 or L2 is high or low; and when power comes back within range (102V-132V) the unit will begin the Delay as described above before returning to the main screen that shows the voltages and currents. Reverse Polarity Conditions If the polarity of the voltages coming into the RV is REVERSE reversed, then the Surge Guard unit will display POLARITY the REVERSE POLARITY until this condition is corrected. Also, current or voltages on ground will be displayed as reversed polarity.
