INSTRUCTION MANUAL: 

ELECTRICAL MANAGEMENT SYSTEM (EMS)  

• 

Weather Resistant: 

Unit can be exposed to outside weather elements; however, 

the unit may not be submerged. Unit is designed to be mounted or used vertically.

• 

Microprocessor Controlled: The EMS utilizes a state-of-the-art microprocessor with 

proprietary software.

• 

Built-in Locking Bracket:

 Helps prevent theft by securing the EMS to the power 

source pedestal using a lock, such as a bicycle cable lock.

NOTE: Provided you have the proper adapter the EMS may be used with 15A, 20A or 30A 

service and will provide full protection; however, reduced power will be available so you 

should limit your power consumption

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. This does not stop you from using a 

 

“generator plug” that ties together neutral and ground as this is perfectly safe 

 

when using a generator.

• 

Do not exceed the rating on the EMS for any reason. These devices are designed 

to be reduced down to 120V/15A and maintain full protection. 

• 

Do not modify the EMS in any way as this will void the warranty, could result in 

possible shock, and/or a fire hazard or compromise protection.

• 

It is important to always check the pedestal power outlet for charring; this 

condition means the AC receptacle is providing a weak connection. Should this 

condition exists, DO NOT USE as it could result in possible melting of the RV 

power plug.

• 

When running an extension cord from the RV to the pedestal power always use a 

 

6 gauge cable for your 240 Volt, 50Amp device and/or a 10 gauge cable for your 

 

120 Volt, 30Amp device. Ensure your cable is rated for outdoor use and we 

recommend the length not to exceed 20-25’. Taking these preventative measure 

 

can help to reduce the risk of electrical shock and/or fire.

• 

Whenever servicing or installing the EMS, or any other AC powered device, 

 

make sure AC power is disconnected.

• 

NEVER plug the EMS into an inverter. This does not preclude using 

 

inverter-generator.
