NOTE: These fuse blocks meet the National Electrical Code requirements for overcurrent protection. Xantrex offers the DC175 and DC250 in an enclosure for applications requiring NEC compliance for both overcurrent protection and a DC disconnect. The Trace™ brand fuse block (TFB) protects the power system’s DC wiring should an overcurrent condition occur. The fuse block is placed between the battery’s ungrounded conductor (usually the positive cable) and the DC input terminal of the inverter. The TFBs include a fast acting, current limiting class-T fuse providing extremely fast protection when...

Installation Mounting NOTE: It is not recommended to locate the fuse block inside the enclosure with the batteries where explosive gases may exist. Locate the fuse block within 18 inches (45 cm) of the battery. It should be placed in a location where it is easily accessible should the fuse need replacing. 1. Squeeze the clear plastic protective cover and remove it from the fuse block base. Use the fuse block base as a template for location of the four mounting holes. The fuse block should be mounted to a secure surface. Allow at least 6 inches (15 cm) from the fuse contacts to allow for removal...

Installation (continued) Cable Installation into Fuse Block For Fuse Blocks designed for C-Type Battery Cables (TFBxxxC) 1. Strip back 1 inch (2.5 cm) of the insulation on the battery cable. Insert the cable into the terminal block (ensure all conductor strands are in the block) See Figure 3. Tighten the hex screws to 10-15 ft/lbs.

Reinstall the hardware as it was originally stacked on the fuse. NOTE: Fuses are NOT covered under the limited warranty. Use a hex socket and remove the two nuts (and split washers) securing the fuse. Note the hardware installed and the order of how it is stacked. This is important to prevent excess heat which can cause the...
