Preparing Your Site for Installation

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 part of the building installation. Install only in accordance with national and local wiring regulations.
