Chapter 1 Introducing the Sensor
Site and Safety Guidelines
Power Supply Guidelines
Follow these guidelines for power supplies:
•
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.
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.
To remove and replace components in a sensor, follow these steps:
Step 1
Remove all static-generating items from your work area.
Step 2
Use a static dissipative work surface and wrist strap.
Note
Disposable wrist straps, typically those included with an upgrade part, are designed for one time
use.
