Grounding

The chassis and equipment rack must be properly grounded. Electrostatic discharge (ESD)
damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle
strap and always connect an ESD strap (with banana plug) to the ESD connection socket
(grounding jack) on the front of the chassis.
The ESS-1 includes an additional grounding jack on the rear panel of the chassis. If DC power is
used, then the ground terminal must be connected. See
page 55.
Warning:
(earthing) connection points are through the IEC60320 appliance inlets. Grounding (earthing)
points on the rear of the equipment are for equipotential bonding only and are not the safety
grounding (earthing) points for the equipment. Lack of proper grounding (earthing) of the
equipment may result in a safety hazard and excessive electromagnetic emissions. Refer to
Table 11 on page 34 for descriptions of common grounding-type (earthing) power supply cords.
If you ground the equipment by a method other than those provided in this manual, those means
should be in compliance with all local wiring regulations and practices.
7450 ESS-1
Install the 7450 ESS-1 in standard sized equipment racks or a stable flat surface.
Install in clean, dry, ventilated, and temperature-controlled rooms.
Verify that the rack is properly bolted and braced and is properly grounded to a grounding
electrode.
Install the chassis into the equipment rack before installing components.
Table-stacked units must not be taller than 8 units high.
Use only power cords that have a grounding (earthing) path. Main grounding
