GENERAL INFORMATION
The Parallax Power Supply 7100 series power converter is a solid-state electronic
power supply and is maintenance-free. These revolutionary RV power converters
utilize technology developed for power supplies in computers that provides a clean
and stable, voltage-regulated output while also providing safety features designed
to help protect the converter against over-temperature and output overload.
The Parallax 7100 series electronic power converter has been tested to comply with
stringent safety standards and is Intertek/ETL listed.
Refer installation and servicing of this product to qualified service personnel.

120-VOLT AC PANELBOARD
The 120-volt AC panelboard section of the 7100 series is located behind the
decorative door in the upper left-hand corner. This section contains the 120-volt
AC main and branch circuit breakers for your RV. One of the breakers controls
the 120-volt power to the 12-volt converter section located in the lower half of the
7100.
Check the breaker identification label below each breaker for what each branch
circuit breaker controls.
If the 7100 series DC power converter is not working, first confirm the RV supply
or “shoreline” cord is plugged into a live circuit. Then check all the 120-volt
breakers in the panelboard to make sure they are “on”. If a breaker is tripped,
follow the instructions below to reset the breaker. If the breaker trips again,
consult an electrician or certified RV technician.
The 120-volt circuits may be turned on by flipping the breaker handle up to the
“on” position or off by flipping the handle to the “off” position. To reset a tripped
breaker, move handle to off then on.
CONVERTER OPERATION
The Parallax 7100 series 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.
Caution: When installing a battery, always verify wiring polarity. Connecting a
battery with reverse-polarity wiring will blow the power converter main fuses
located on the 12-volt DC distribution fuse block.
If the 12-volt load exceeds the converter output rating, the output voltage will drop
to prevent any further increase in current. Turn off some DC lights or appliances
and the output voltage will automatically recover. The same will occur if the
converter exceeds safe operating temperature limits. Check to see that the
converter’s air circulation is not blocked, or turn off some of the 12-volt load.
If any 12-volt appliance fails to operate, check your RV’s 12-volt distribution fuse
block located behind the decorative front door in the upper right hand corner of the
converter and inspect all fuses. If a fuse is open or “blown”, replace it with the same
size fuse (never install a larger fuse). If the fuse opens again, have an electrician or
certified RV technician locate the circuit trouble. Replace blown fuses with Littelfuse
type 257, Bussman type ATC, or Possing Electronic type ATP fuses only.
CONVERTER COOLING SYSTEM
The 7100 series electronic fan cooling system contributes to long converter life and
trouble-free operation. The fan turns on automatically when required to cool the
electronic components in the converter. The amount of airflow required is necessary
to properly cool the converter components and the associated “air sound” generated
may be audible in quiet environments.
MOUNTING LOCATION & CLEARANCES
The 7100 series converter is designed for indoor use only.
DO NOT mount in harsh environments; avoid areas where high levels of dust, dirt, or
moisture may occur.
DO NOT mount the power converter in battery compartments or in areas where
flammable materials are stored.
Mount to a vertical surface with the front of the converter open to the living area of the
RV.
Provide a minimum of 22 inches clearance to the front of the converter. Leave adequate
room behind the converter for wire routing and air intake for the fan located at the rear of
converter.
DO NOT mount in zero-clearance compartments; overheating and thermal shut down will
result.
INPUT SUPPLY REQUIREMENTS
Connect to a 120 VAC 60HZ 3-wire with ground supply. DO NOT use circuit protection
larger than 30-ampere.
CONVERTER TO BATTERY WIRING
The battery supply wire from fuse block terminal “POS +” to the battery must be of
adequate size and rating and must be protected within 18 inches of the battery with
an appropriately rated fuse or breaker.
