Progressive Industries ADT-230 - Manual (Page 2)

WARNINGS
Never plug your ADT-230 into power before testing both receptacles
with a circuit tester.
The ADT-230 will not operate on a GFCI circuit and requires two
separate circuits.
Do not exceed the rating of the ADT-230 for any reason.
Do not modify the ADT-230 in any way. This will void the warranty
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!
When running extension cords from the RV to AC power, always use
appropriate-sized cable. 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 resulting in voltage loss, plus it may result in an
electrical fire.
ADT-230
The ADT-230 can be used on two 30 amp receptacles OR you can
add another adapter and plug into two 20 amp receptacles.
