3.6 Setting of Switch Positions and Mounting of the DLI Card
Note:
When handling circuit cards, observe the following precautions:
(1) Protection Against Static Electricity
When setting switches on circuit cards, use a Portable Field Service Grounding Kit in order to prevent dam-
age to static-sensitive components.
Example: 3M Model 8012, consists of:
•
2× 2 VELOSTAT
•
15 ft. Ground Cord
•
CHARGE-GUARD
•
Before handling any circuit cards, first spread out the work mat, then connect the ground cord to the frame
or other ground source.
•
If a CHARGE-GUARD wrists strap is to be used, connect the wrist strap to the frame or other ground using
the provided cable.
(2) Handling Circuit Cards
Whenever possible, do not handle circuit cards with bare hands.
•
The only portion of the card that can be touched is its edge. Do not touch the surface or the mounted com-
ponents. Doing so may damage the card.
•
Handle circuit cards with care.
(3) Mounting or Removing Circuit Cards when the system is in operation
•
Never mount or remove a circuit card without first setting its MB switch to the UP position.
