Page 3: General Information
All wiring must conform to local, national and regional codes and regulations. Use cop- per conductors ONLY for all wire connections. Do not exceed the electrical ratings for the WF-8900-MBA-AD Series Power center or the equipment connected to it. Failure to follow these precautions may cause permanent failure and/or electrical shock which could result in severe personal injury or death. -
Page 4: Electronic Current Limiting
Electronic Current Limiting In the event that the output current exceeds the maximum rating for the WF-8900 Series Power Center converter, the output current will remain constant but the output voltage will begin to drop. If this occurs, the unit will recover once loads are reduced. 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. -
Page 5: Operational Features
LED INDICATORS WFCO converters have integrated LEDs which inform the user on which mode it is in. As it pertains to charging profiles, green is intended for the lead-acid charge profile while blue is intended for the lithium charge profile. The most important light of them all for charging is red, which signals bulk charge mode. -
Page 6: Two-Stage Smart Charging
POWER MODE The converter normally provides a constant target output voltage of 13.6 VDC (nominal) to power all the branch cir- cuits. 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. - Page 7 - Converter size – A 55-amp converter can charge a battery faster than a 35-amp converter. The charging profile is not set in stone. WFCO Auto-Detect converters monitor the current over time at the end of every charge cycle. So, in the event of a misdetection due to external factors, once the factors are addressed or no longer present, the converter can still properly detect the battery type during the next charge cycle.

Page 8: Troubleshooting Instructions
TROUBLE SHOOTING INSTRUCTIONS Troubleshooting the WF-8900MBA-AD Series MAin Board Assembly Converter Output Voltage Before checking the WF-8900MBA Series Main Board Assembly output voltage, disconnect the battery cables at the battery. Make sure the converter is plugged into an AC source (105-130 Volts). Check the converter output voltage at the battery with a voltmeter. - Page 9 Should it be determined that the WF-8900MBA Series Main Board Assembly needs to be replaced, re- moval 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. Remove and set aside the Reverse Polarity Fuses located on the fuse board to disconnect the converter section from the rest of the RV’s DC power.
