INSTRUCTION MANUAL:
ELECTRICAL MANAGEMENT SYSTEM (EMS)
Warnings
•
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 EMS 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 EMS for any reason.
•
Do not modify the EMS 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, 50 Amp device or a 10/3 AWG
cable for your 120 Volt, 30 Amp 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 EMS into an inverter. EMS units can be used with inverter-
generators.
Power Connection
WARNING: To minimize shock hazard, follow these instructions:
1)
Turn off power to the RV before connecting or disconnecting power cable.
2)
Connect power cable at the RV first.
3)
Disconnect power cable at the AC power source first.
4) Close inlet cover tightly.
Maintenance Warning
• Before each use, examine the plug and receptacle of the EMS, 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.
• Carefully follow the wiring instructions supplied with all replacement devices to
insure proper operation.
