OPERATIONAL FEATURES
Power Factor Correction
This feature causes the unit to consume
cost or allows more AC devices to be used.
Reverse Battery Protection
This feature prevents permanent damage to the converter from an incorrect
battery connection. Replace only with “ATC-style” fuses.
Automatic Cooling Fan
The fan is variable speed and current controlled.
Electronic Current Limiting
Automatically shuts down power during overload or short-circuit conditions.
Automatically returns to normal operation after conditions are corrected.
If the unit shuts off from an overload condition, the user needs to reduce the
load below 50% in order for the unit to come back on.
Over-Temperature Protection
Unit will shut down if temperature is too high.
Battery Type Selection Switch
For increased battery life span, you can select battery type between
AGM/Lead-Acid and Gel-Cell type of batteries. Gel-Cell type of batteries
requires lower output voltage and there is no need for bulk mode. Default
setting is (up) AGM/Lead-Acid type of batteries.
Manual Bulk Charging Switch
For AGM/Lead-Acid type of batteries, with a push of a button on the front
cover you can manually bring the converter to bulk charge mode.
LED Indicators
Lights show operating status of the converter:
- Green LED: converter powered up
- Amber LED: On when unit is turned off and the connected battery is full,
flickering occurs when battery is approaching low voltage.
- Red LED: converter is overloaded
less power, which reduces electric

OPERATIONAL FEATURES
All WFCO power converters are automatic three-stage switching
power supplies. The converter senses which mode it needs to be in by
checking the RV system voltage.
The three modes/stages of operation include:
Absorption mode/Normal operation
Nominal battery charge and supplies power to appliances
Bulk mode/Charge mode
Fast battery charge and supplies power to appliances
Float mode/Trickle charge
Trickle battery charge during storage
Absorption Mode: During this mode, the converter output is in the
13.7 Vdc range. This is the normal operation mode. This mode provides
the 12 Vdc and current required by the 12 Vdc RV appliances, as well as
slow charging the battery.
Bulk Mode: In this mode, the output voltage of the converter will
switch to 14.4 Vdc range for a maximum of four hours (not applicable
to Gel-Cell type of batteries). If the converter cycles between
“Absorption and Bulk mode,” there could be a shorted battery cell or
other issues.
Float Mode: In this mode, the converter is charging the battery
with a trickle voltage in the 13.2 Vdc range. When the converter senses
a demand (by turning on lights), the converter automatically returns
to the “Absorption mode.”

If there is no DC output, first check the reverse polarity fuses on the back of
the WF-6800 Series deckmount converter. Then, visually inspect the fuses
for any breaks; if none are found, use a continuity tester to check for continuity.
If the reverse polarity fuses are blown, it means the RV battery was accidentally
connected in reverse, either at the battery or at the converter. Reconnect
properly, then replace the fuse with the same type and amp rating as the
original “Littelfuse ” Type 257 automotive-style fuse.
IMPORTANT: These fuses protect the converter from damage in the
event that the RV battery is accidentally connected in reverse. A reverse
battery connection, even for a second, is the reason that these fuses will blow

for a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
The WF-6800 Series units are UL-Listed, and cUL-Listed (Canadian).
They comply with FCC Class B requirement (see below).

TROUBLESHOOTING INSTRUCTIONS
Before the converter output voltage can be checked, it is necessary to disconnect battery
output wires from the battery terminals. Insulate each wire to prevent shorts. Plug the
converter into a 120 VAC source. Using a voltmeter, check the converter output voltage.
Place the Positive + (red) probe in the POS + output (red) and place the Negative -
(black) test probe into the NEG - (black) output terminal of converter. Be sure you have
good connections at the terminals. If the voltage reads in the 13.2 Vdc-14.4 Vdc range,
the converter is functioning properly. Add more load to make sure converter is able to
keep the output voltage between .
13.2 Vdc-14.4 Vdc range
If the converter output voltage reads in the 13.2 Vdc-14.4 Vdc range and
the battery is not charging, check for:
- an open inline fuse in the battery wire (if provided)
- an open wire between the converter and the RV battery
- loose ground
- improper torques
If the converter fuses and AC voltage are good, but the converter output
still reads zero volts, the converter is not functioning properly.
