• Open Circuit: If the Surge Protector unit detects an open hot condition, no lights will turn
on. This is a condition where the hot wire is either disconnected or broken somewhere
along its path, and every device connected to the wire after the break will lose power.
An open hot condition could harm you and/ or your RV electrical system and electrical
equipment. If this indication occurs, disconnect power to the AC power source and report
the open neutral wiring condition to the park manager or a qualified electrician before
plugging your RV power cord into the receptacle of the Surge Protector.
• If Surge Protector Indicator light is off: the surge protection module is depleted and is no longer
providing surge protection to your RV. It is recommended that you replace the surge protector.
• If OVER HEAT WHEN ON red light is on: the surge protector is overheating.
1. If the Surge Protector indicates correct wiring, disconnect power at the AC power source. Plug the
cable from your RV into the Surge Protector receptacle. Verify that the plug connection between the
AC power source, the Surge Protector, and the RV cable are secure and fully inserted.
2. Re-apply power to the AC power source. Power will now pass through the Surge Protector to the RV.
NOTE: Provided you have the proper adapter, the Dicor Surge Protector may be used with 15A, 20A, 30A
or 50A service and will provide full protection.

Dicor Power Surge Protection
DP-SP50A-P
INSTRUCTION MANUAL
5-Mode Surge Protection: This feature provides five modes of surge protection. Line 1 to neutral (L1-N),
line 2 to neutral (L2-N), neutral to ground (N-G), line 1 to line 2 (L1-L2) and line to ground (L-G). The total
joule rating is 5000 J. Response time is less than 1 ns (nanosecond).
Auto ON/OFF : If input voltage drops below the set voltage range or exceeds the set voltage range, the
circuit will be disconnected to protect the electronic equipment within a few milliseconds. Once voltage
stabilizes and returns to normal, the circuit will restore power.
Surge Indicator: The Green Surge Protection light on the bottom left of your Dicor Surge Protector device
indicates that your surge protector is functioning correctly and is providing protection to the devices you
have connected to it.
This light should remain ON as long as the surge protector is plugged into an outlet and power is ON. If this
light goes out at any time, it means that your surge protector has served its purpose on protecting your
equipment against damaging voltage fluctuations, surges, or spikes. If this happens, your surge protector is
no longer providing surge protection to your RV and should be replaced.
NOTE: Provided you have the proper adapter, the Dicor Surge Protector may be used with 15A, 20A, 30A or
50A service and will provide full protection.

WARNING: To minimize shock hazard, follow these instructions:
1. Turn off power to the RV before connecting or disconnecting power cable.
2. When connecting power, connect the power cable at the RV first before plugging into the AC power
source.
3. When disconnecting power, disconnect power cable at the AC power source first
4. Close inlet cover tightly.
• Before each use, examine the plug and receptacle of the Surge Protector, the male plug of the RV
power cord, and the receptacle on the AC power source. Look for signs of discoloration which indicates
overheating.
• If any connection shows signs of overheating, replace both mating parts immediately.
• Use brass wire brush provided to remove any dirt or carbon build-up from brass prongs on your surge
protector or extension cord.”
• Carefully follow the wiring instructions supplied with all replacement devices to insure proper operation.
• RV wiring is different than house wiring. In an RV, neutral and ground conductors are isolated whereas in
a house they are bonded at the service panel. Therefore; never connect neutral and ground as this can
result in a ground fault condition, electric shock, and/or a fire hazard.
• The Dicor Surge Protector can be used with a generator. A bonded neutral generator is recommended.
If your generator is not neutral grounded you can find articles on multiple websites detailing ways to
properly bond a generator.
• Do not exceed the electrical rating on the Dicor Surge Protector for any reason.
• Do not modify the Dicor Surge Protector in any way as this will void the warranty, could harm you and/or
your RV electrical system and electrical equipment or compromise protection.
• When running an extension cord from the RV to the AC power source always use a 6/4 AWG or 6/3 +
8/1 AWG cable for your 240 Volt, 50Amp device or a 10/3 AWG cable for your 120 Volt, 30Amp device.
Ensure your cable is rated for outdoor use and we recommend the length not to exceed 25’. Taking these
preventative measures can help to reduce the risk of electrical shock and/or fire.
• NEVER plug the Dicor Surge Protector into an inverter. Dicor Surge Protector units can be used with
inverter-generators.

OPERATING INSTRUCTIONS
WARNING: DO NOT plug your RV power cord into the receptacle of the Dicor Surge Protector at this time.
1. Be sure that power is disconnected at the AC power source. Plug the Surge Protector unit into the
appropriate receptacle.
2. Re-apply power to the AC power source and monitor the Surge Protector unit. Verify that all top three LED
indicator lights are ON and Green. If any of the top three LED indicator lights are NOT ON or Red, refer
to the LED light indicator breakdown on following page. If a fault condition is indicated, there may be
a problem with the pedestal wiring or with the power at your location. Consult a licensed electrician to
correct the fault condition or move your RV and connect to a different pedestal.

• Correct Wiring: If the Surge Protector unit detects a correct wiring condition, the surge
protection light will turn on and the three green lights will turn on. If this condition occurs,
please proceed to Step 3 on reverse side of page.
• Open Neutral: If the Surge Protector unit detects an open neutral condition, the first green
light will turn on. This is a condition where the neutral wire is disconnected and could pose a
shock hazard. An open neutral condition could harm you and/ or your RV electrical system and
electrical equipment. If this indication occurs, disconnect power to the AC power source and
report the open neutral wiring condition to the park manager or a qualified electrician before
plugging your RV power cord into the receptacle of the Surge Protector.
• Open Ground: If the Surge Protector unit detects an open ground condition the last two green
lights will turn on. Open ground is a condition where the three-prong receptacle is not connected
to an equipment grounding conductor or the neutral and ground wires are not bonded together
creating an electrical safety hazard. An open ground condition could harm you and/or your RV
electrical system and electrical equipment. If this indication occurs, disconnect power to the AC
power source and report the open ground wiring condition to the park manager or a qualified
electrician before plugging your RV power cord into the receptacle of the Surge Protector.
• Missing L1 120V: If the Surge Protector unit detects a missing line 1 condition the first two green
