Progressive Industries EMS-HW50C - Manual (Page 3)

Warnings
• Do not exceed the rating on the EMS for any reason, however,
these devices are designed to be reduced down to 120V/15A, and
still maintain full protection.
• Do not modify the EMS in any way. This will void the
warranty, compromise protection and could result in possible
shock and/or fire hazard.
• It is important to always check the pedestal power outlet for
charring; this condition means that the AC receptacle is
providing a weak connection. DO NOT USE! 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.
• When running extension cords from the RV to AC power,
always use a 6 gauge cable for your 240 Volt, 50 Amp system.
Make sure that the cable is rated for outdoor use to reduce the
risk of electrical shock. Small gauge cable will have a higher
resistance and will result in voltage loss, plus it may result in an
electrical fire.
• Whenever servicing or installing the EMS, or any other AC
powered device, make sure AC power is disconnected.
• RV wiring is different than the wiring found in homes; the
neutral and ground conductors are isolated in the RV, unlike in a
home where they are tied together at the service panel. The
reason is: homes have a bonded ground system, whereas RV’s
do not. Therefore, never bond the neutral and ground together
for any reason. This will create a ground fault condition, and
may result in electric shock and/or fire hazard.
• Never solder the ends of the wires that you attach during
installation. This includes the Red, Black and White wires.
• Never plug the EMS into an inverter.
