1Fuse Links (Odd Number Modules)

2Fuse Links (Even Number Modules)

Each of the eight modules is pro- tected from overload by a pair of link-type fuses FX1 and FX2 (“X” represents the number of the appli- cable module, 1−8). If one fuse link for a module opens, low weld output is available at the applicable mod- ule. If both fuse links open, no weld output is available at the affected module.

To replace fuse(s), proceed as follows: Remove upper rear panel. Check fuse(s), and replace if nec- essary. Reinstall upper rear panel.

6-3. Blank Module Panel

Y Turn Off polyweld system, and disconnect input power before inspecting, maintaining, or servicing.

A blank module panel is included with each polyweld system. If a module is removed, install the blank module panel in the location where the module was removed before using the remaining modules. This panel prevents the touching of inside parts and wires, and ensures proper air flow through the polyweld system.
