Page 3: General Information
WF-8700 Series Power Center Safety Features Reverse Battery Protection The WF-8700 Series Power Centers will charge the 12-volt House battery if installed. A battery DOES NOT have to be installed for WF-8700 Series Power Center converter operation. When a battery is installed, a reverse polarity fuse protects the converter circuitry. The fuse is located along the bottom of the row of fuses. -

Figure 1 Automatic Cooling Fan The cooling fan in the WF-8700 Series Power Center is incremental and is controlled by the current drawn out of the converter to the applied load. NOTE: The WF-8712P does not have a fan. The on-board microprocessor increases fan speed as the total load increases and decreases fan speed as the load decreases. -

Bussmann type ATC AC Circuit Breakers (120/240 Volts) The AC Breaker side of the WF-8700 Series Power Center is located on the left side of the enclosure. The WF-8700 Series Power Center accepts standard residential breakers. The WF-8712P and WF-8725P have spaces for a 30 Amp Main and up to 3 Branch breakers when using duplex breakers. - Page 6 Manufacturer Model/Cat.

Ground and Neutral bars. The DC wires protruding from the back of the WF-8700 Series Power Center have been connected to the DC circuits in your RV by the RV manufacturer. In a similar fashion, label and disconnect these wires. -
Page 10: Installation Instructions
Mounting the Enclosure The WF-8700 Series enclosure should be mounted in an accessible area such as a wall or in the side of a cabinet. The front of the enclosure should not be obstructed to allow free air flow for the cooling fan. -
Page 11: Wiring The Dc Fuse Board
Wiring the DC Fuse Board Make sure the house battery is disconnected before beginning the DC wiring. Determine what DC loads are to be connected to the fuse board and what position they will occupy. All 4 circuits on the WF-8712 and WF-8725 Power Centers have up to 20 Amp ATO or ATC fuses installed. - Page 12 All models have wire lead connections. Strip approximately 1/4” of insulation from the wires and attach to the appropriate connected load using a wire nut or other approved method. Make sure the connectors are tightly secured. Connect the heavy wire (Red) coming from the battery to the Red 10AWG wire coming from the back of the enclosure.
