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.
WARNINGS
POWER CONNECTION & DISCONNECTION
MAINTENANCE WARNING
• Correct Wiring: If the Surge Protector unit detects a correct wiring condition, the surge
protection light will turn on and the two yellow lights will turn on. If this condition occurs,
please proceed to Step 3 on reverse side of page.
• Open Ground: If the Surge Protector unit detects an open ground condition the first
yellow light 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.
• Reverse Polarity: If the Surge Protector unit detects a reverse polarity condition, the
first yellow and red light will turn on. A reverse polarity 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 reverse polarity wiring condition to the park
manager or a qualified electrician before plugging your RV power cord into the receptacle
of the Surge Protector.
• Open Hot: 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.
• Open Neutral: If the Surge Protector unit detects an open neutral condition, the first
yellow light, red light and second yellow 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.
• Hot/Ground Reverse: If the Surge Protector unit detects a hot/ground reverse, the red
light and second yellow light will turn on. Hot/ground reverse simply means the hot wire
and the ground wire have not been installed properly. 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.
• Hot on Neutral with Hot Open: If the Surge Protector unit detects a hot on neutral with
hot open, the red light will turn on. This indicates there is an open neutral with reverse
polarity. 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.
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. 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.
