1.1.1 Safety Summary
The following safety precautions must be observed at all times during operation, service, and
repair of this equipment. Failure to comply with these precautions, or with specific warnings
elsewhere in this manual, violates safety standards of design, manufacture, and intended use of
this product. HPS/RFL assumes no liability for failure to comply with these requirements.
Ground the Chassis
The chassis must be grounded to reduce shock hazard and allow the equipment to perform
properly. Equipment supplied with three-wire AC power cables must be plugged into an
approved three-contact electric outlet. All other equipment is provided with a rear-panel
protective earth terminal, which must be connected to a proper electrical ground by suitable
cabling. The location of the protective earth terminal on the HPS/RFL™ GARD Pro™ system
is shown below. Refer to the wiring diagram supplied with the unit for additional information on
chassis and/or cabinet grounding.
A protective earth stud at the lower right rear of the HPS/RFL GARD Pro system chassis is the
main ground for the HPS/RFL GARD Pro system.
