Grounding Wrist Straps
Using a grounding wrist strap (see Figure 1) is recommended when installing
and operating the AC 60.
Follow these guidelines for grounding wrist straps:
•
Attach at least one wrist strap to a common ground for each
unit/electronic rack to be handled.
•
Wrist straps or wrist strap cords should have built-in 1 mega ohm
(minimum) resistors for operator protection.
•
Wrist straps and wrist strap cords should be UL listed.
•
Ensure that the cord for the wrist strap is long enough so that you can
wear it while working at the cabinet front or back.
Place the wrist strap so you can touch it first and discharge through it instead
of discharging on the cabinet.
Floor Covering
Be sure that the room has antistatic flooring (conductive mat, carpeting, or
tiles) to minimize static buildup as you walk across the room. Follow these
guidelines for installing and maintaining proper flooring:
•
The use of grounding foot straps is recommended while walking in rooms
providing antistatic flooring. Foot straps provide additional protection
against electrostatic discharge. Foot straps should have built-in 1 mega
ohm (minimum) resistors for your protection.
•
Wool carpeting is not an acceptable flooring.
Other types of carpeting (when used) require daily spraying with a topical
antistatic chemical before any work in the system room is performed. This
