• The voltage should be within 13.8 and 14.0 volts.

(The meter of the tester should be calibrated

periodically.)

• If converter is not within these voltages, have it

serviced by a qualified technician or replace it.

A label on the inside of the converter door lists the

circuits and what each fuse powers.

Converter Operation

The electronic power converter is designed to

supply the nominal 12-volt-filtered DC power for

all 12-volt operated devices encountered in RV

service. Although the converter is an excellent

battery charger, the converter does not require a

battery to be connected to it for proper operation.

NOTE

When installing a battery (s), always observe

polarity. Connecting a battery in reverse polarity

will blow the power converter main fuses located

on the 12-volt DC distribution fuse block

120-Volt AC Panel Board

The AC panel board section contains the 120 VAC

branch circuit breakers for your RV. One of the

breakers controls the 120-volt power to the 12-volt

converter section. This breaker may also control

another branch circuit. Check the label next to each

breaker for what each branch circuit breaker

controls.

The 120-volt circuits may be turned on by setting

their breaker handle up, to the ON position, or off

by setting the handle down, to the OFF position. To

reset the tripped breaker, move handle to OFF then

ON.

The system incorporates GFCI breakers that

implement an auto self-test functionality. When

turned off, these breakers require external AC

power to be present, or the AC inverter enabled,

before they can be turned back on. If AC power is

present from one of these two sources, and the

breaker refuses to stay on consult an electrician or

certified RV technician.

Fuses and Breakers

Breakers

The distribution panel was

designed to use a 30 Amp

120Volt main breaker with

branch circuits. Double

breakers may be used for the branch circuits.

Should a breaker become faulty replace with the

same type breaker only. Use only approved circuit

breakers and 12V fuses.

NOTE

When replacing circuit & breakers replace with

the same type and rating as the original.

12 VDC Fuses

Each 12 VDC circuit in the

distribution panel was

designed for a maximum of

a 20-amp automotive style

fuse. Should one need to be

replaced, be sure to replace it with the same type

and Amp rating as originally supplied by nüCamp

RV. Replacing it with either a higher or lower Amp

fuse could result in the panel not functioning

properly.

Reverse Polarity Fuses

The power converter is equipped with reverse

polarity fuses, should these fuses "blow" either

during the manufacturing process or while

connecting the battery, replace with the same type

and rating fuse as originally provided with the

equipment.

The power converter is not weather resistant nor

designed for installation in wet locations. The

power converter must be protected from direct

contact with water.
