Introduction

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.

Tools/Materials Required

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 a short circuit occurs. When the fuse is properly matched to the system current, its time delay allows the inverter to surge to full power without blowing the fuse. A plastic cover prevents accidental short circuits to the fuse terminals. Fuse sizes include 110, 200, 300, 350 and 400 amps.

There are two types of fuse blocks available. The TFBxxxC fuse block has “set” screw lugs for cables with no terminal connector’s on the ends (hereto referred to as C-type battery cables). The TFBxxx fuse block has stainless steel bolt connections for cables with ring terminals (hereto referred to as ring-lugged battery cables). Both fuse blocks include a black polycarbonate, fiberglass reinforced base and a clear polycarbonate snap-on cover.

•4 screws (type depending on mounting material)

•5/16 inch allen wrench (for C-type fuse blocks only)

•9/16 inch socket for 3/8" hex nuts

•1/2 inch socket for 5/16" hex nuts

•assorted screwdrivers

•knife

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.

2.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 without shorting to a grounded object.

3.Use appropriate hardware (not supplied) to mount the fuse block.
