•

Cable paths and connector locations should be noted prior
to disassembly. If cables are run in locations other than
those indicated by the manufacturer, the unit may exhibit
HI-POT failure, fuse blowing, or may not close properly.

•

Torque specifications for screws are provided under the
installation instructions.
