• 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
lights will turn on. This condition could be due to a faulty or loose connection or a fault with the
pedestal receptacle not supplying power. A missing line 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 L2 120V: If the Surge Protector unit detects a missing line 1 condition the first two
green lights will turn on. This condition could be due to a faulty or loose connection or a fault
with the pedestal receptacle not supplying power. A missing line 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 light
will turn red and last two lights will turn green. 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.
• L1 & Ground Reverse: If the Surge Protector unit detects a hot/ground reverse, the first light will
turn red and second light will turn green. 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.
• L2 & Ground Reverse: If the Surge Protector unit detects a hot/ground reverse, the first light will
turn red and third light will turn green. 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.
