GENERAL INFORMATION WF-8900 Series Power Center Safety Features Reverse Battery Protection The WF-8900 Series Power Centers will charge the 12-volt House battery if installed. A battery DOES NOT have to be installed for WF-8900 Series Power Center converter operation. When a battery is installed, two reverse polarity fuses protect the converter circuitry.
The fuse values and quantity vary depending on which WF-8900 Series Power Center you have. Refer to the table and drawing below. • WF-8935 – 40A (1) *NOTE: Only one of the two Reverse Polarity terminals is used. • WF-8945 – 30A (2) •...
Short-Circuit Protection Should a short circuit occur in the RV, the WF-8900 Series Power Center converter will drop the voltage output to zero volts. If the short-circuit condition is removed and no other fault conditions are detected, the converter will resume normal operation. However, short-circuit conditions are dangerous, and an RV will require inspection by a qualified service technician.
Manufacturer Model/Cat. No./Type Cutler Hammer Type BR and C, Type BRD, BD and A Thomas Betts Type TB or TBBD ITE/Siemens Type QP or QT Square D Type HOM or HOMT Murray Type MP-T or MH-T General Electric Type THQL When replacing any of the installed circuit breakers, the replacement should be of the same manufacturer, type designation, and equal interrupting rating, not to exceed 30 A.
The converter normally provides a constant target output voltage of 13.6 VDC (nominal) to power all the branch circuits. However, it is current limited, and if the output (load) current reaches its maximum, the output voltage will drop as necessary to hold the converter’s maximum output current level (the Amperage rating) without exceeding it.
If the above checks have been made but the converter output still reads 0.0 VDC, the converter is not functioning properly. Contact the Arterra Distribution Power PROs at 1 (877) 294-8997. Before placing the call, please have available the WF-8900 Series Power Center model number from the front panel label and the 14-digit serial number from the bar code tag located on the MBA mounting plate.
Should it be determined that the converter section of the WF-8900 Series Power Center needs to be replaced, removal of the Main Board Assembly is a simple process. Replacing the Converter Section (MBA) Make sure no AC power is coming into the RV from either the Shore Power cord or an on-board generator.
INSTALLATION INSTRUCTIONS Installing the WF-8900 Series Power Center Mounting the Enclosure The WF-8900 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.
Figure 5 Figure 6 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. Circuits F10 and F11 can be used for slide-outs or other higher current loads and can have a maximum 30 Amp ATO or ATC fuse installed.

All models have output screw terminal connections. Strip approximately 1/4” of insulation from the load’s wire and insert into the screw terminal. Tighten the terminal to the torque specified on the back of the enclosure. Connect the heavy wire (Red) coming from the battery to the POS+ lug located directly below the Reverse Polarity fuses.
