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.
The result will cause 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.

• 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, compromise protection and could result in possible
shock, and/or a fire hazard.

• 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.

• Progressive Industries recommends you have a certified

electrician or an authorized dealer perform the installation of the
EMS unit.

• All AC power extension cords in conjunction with your EMS unit

should be rated 10 gauge for 120V, 30A systems or 6 gauge for
240V, 50A systems and rated for outdoor use to reduce the risk
of electrical shock. We recommend the length not to exceed
20-25’. Small gauge cable will have a higher resistance and can
result in voltage loss or an electrical fire.

• Whenever servicing or installing the EMS, or any other AC

powered device, make sure AC power is disconnected.

• Never solder the ends of the wires you attach during installation,

this includes any red, black and/or white wires
