Connect the AC input terminals to a fused power source to prevent overloads and protect both the control unit and RV circuits. Ensure the polarity matches the line and neutral connections.

Attach the DC output leads carefully to the battery bank, observing correct positive and negative terminals. This prevents reverse current flow and damage to sensitive electronics.
Use an inline fuse or circuit breaker rated for the expected load of appliances. This adds a layer of protection in case of short circuits or sudden spikes in current.
Secure all connections with proper terminal blocks or crimped connectors to reduce resistance and prevent loose contacts that can cause voltage drops or sparks.
Check voltage levels before powering devices to confirm correct output. Adjust the module settings to match 12V or 24V systems depending on your RV configuration, and monitor for any heat buildup during initial operation.
WFCO Converter Instructions for Safe RV Power Connections

Connect the AC input terminals to a properly fused power source to prevent overloads. Ensure the line and neutral wires match the polarity on the unit to avoid short circuits.
Secure DC output leads to the battery bank using the correct positive and negative terminals. Improper connections can reverse current flow and damage onboard electronics.
Follow these steps for reliable installation:
- Turn off all power sources before making connections.
- Use crimped ring terminals or proper terminal blocks for all connections.
- Verify tightness to prevent loose contacts that create sparks or voltage drops.
Install inline fuses or circuit breakers on the DC outputs according to the total amperage of connected appliances. This protects the system from overloads or short circuits.
Check output voltage before powering devices to ensure it matches your RV system, whether 12V or 24V. Monitor initial operation for unusual heat or fluctuations that indicate a problem.
Label all connections for future maintenance. Clear identification of input, output, and battery leads helps prevent accidental reverse connections or overloads during repairs or upgrades.
Connecting AC Input and DC Output Terminals

Attach the AC input leads to a fused power source with proper line and neutral identification. This prevents overloads and ensures the module receives stable voltage for safe operation.
Secure the DC output terminals to the battery bank following correct polarity. Connect positive to positive and negative to negative to avoid reverse current that can damage sensitive electronics.
Use reliable connectors and crimped rings for all terminals. Loose connections can cause sparks, voltage drops, and intermittent power issues when appliances draw high current.
Test voltage at the DC outputs before connecting devices. Confirm that it matches your RV system, monitor for heat buildup, and ensure all fuses and breakers are rated for the total amperage load.
