Working in an ESD Environment

Work on ESD-sensitive parts only at an approved static-safe station on a grounded static dissipative work
surface, for example, an ESD workbench or static dissipative mat.

Remove all static-generating items from your work area.

Check the power at the site before installing the chassis to ensure that the power is free of spikes
and noise. Install a power conditioner if necessary, to ensure proper voltages and power levels in the
source voltage.
Install proper grounding for the site to avoid damage from lightning and power surges.
The following applies to a chassis equipped with an AC-input power supply:
– The chassis does not have a user-selectable operating range. Refer to the label on the chassis for
the correct AC-input power requirement.
– Several types of AC-input power supply cords are available; make sure you have the correct type
for your site.
– Install a UPS for your site.
– Install proper site-grounding facilities to guard against damage from lightning or power surges.
Disposable wrist straps, typically those included with an upgrade part, are designed for one time
use.
