Ensuring Overcurrent Protection
The GSS relies on the protective devices in the building installation for protection
against short-circuit, overcurrent, and earth (grounding) fault. Ensure that the
protective devices in the building installation are properly rated to protect the
GSS, and that they comply with national and local codes.
Grounding the GSS
Warning
Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable
grounding is available.
Creating a Safe Environment
Follow these guidelines to create a safe operating environment:
• Keep tools and chassis components off the floor and away from foot traffic.
• Clear the area of possible hazards, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
• Keep the area around the chassis free from dust and foreign conductive
material (such as metal flakes from nearby construction activity).
AC Power
Ensure that the plug-socket combination is accessible at all times, because it
serves as the main disconnecting device. Refer to Appendix A, Specifications, for
the GSS power requirements.
Warning
This product requires short-circuit (overcurrent) protection, to be provided as
