Connecticut Electric Parallax Power Supply Powercenter 7100 Series Owner's Operation/Warranty Manual

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, stable,
voltage regulated output while also providing safety features designed to help protect
the converter against over-temperature and output over-load.
If any 12-volt appliance fails to operate, first check your RV's 12-volt distribution fuse
panel 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 and 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.
If the 7100 series 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
your RV distribution panel to make sure they are "on". If a breaker is tripped, follow the
instructions to reset the breaker. If the breaker trips again, consult an electrician or
certified RV technician.
The Parallax Power Supply 7100 series is ETL listed and has been built with safety in
mind to stringent safety standards. The 7100 series converter is also FCC Class B
certified to minimize interference to electronic equipment.
CONVERTER OPERATION
The Parallax Power Supply 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(s) always observe polarity. Connecting a battery
with the polarity reversed will blow the power converter "reverse protection battery
fuses" located on the 12-volt DC distribution fuse panel.
If the 12-volt load exceeds the converter output rating the output voltage will
drop. Turn off some 12 volt lights or appliances and the output voltage will
automatically restore. 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.
120 VOLT AC PANELBOARD
The AC panelboard section of the series 7100 is located behind the decorative door in
the upper left-hand corner. This panel 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 located in the lower half of the 7100. 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 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.
INPUT SUPPLY REQUIREMENTS
Connect to a 120 VAC 60HZ 3 wire grounded supply with no larger than 30-ampere
"Main" circuit protection.
MOUNTING LOCATION
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.
(HORIZONTAL MOUNTING ONLY)
Mount to vertical Surface with the front of the converter open to the living area of the
RV.
MOUNTING CLEARANCES
Provide a minimum of 22 inches clearance to the front of the converter. Leave
adequate room for wire routing and fan air intake located in top rear of converter.
DO NOT mount in zero clearance compartments; overheating and thermal shut down
will result.
CONVERTER COOLING SYSTEM
The 7100 electronic fan cooling system is a key to long life and trouble free operation.
The fan is never on more than required to cool the electronic components in the
converter.
BATTERY CHARGER PREFORMANCE
The National Electric Code requires that power converters for RV service use, be
marked with an average charge rate, as part of the total continuous output rating.
Average charge rate will depend on several variables such as, condition of the
battery(s), temperature, and the length of time the battery(s) are connected to the
converter. In actual RV use the engine alternator and on board generators are also
possible sources of charging currents.
With all these variables it is difficult to determine the average charge rate from the
converter. In most cases the average charge rate will be very small, in the order of a
few hundred milliamps (1 AMPERE=1,000 MILLIAMPS). Your Parallax 7100 series
power converter is capable of delivering its full rated output to the battery(s) if needed,
but current accepted by the battery(s) will taper off to a few hundred milliamps when the
battery(s) reach full charge.
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.
