6 PCL-813 User's Manual
INSTALLATION
Initial Inspection
When you receive your PCL-813 you should find enclosed:
• One PCL-813 32-Channel Single-Ended Isolated Analog Input Card
• User's Manual
• Utility Diskette, which includes the card's software driver
The PCL-813 was carefully inspected both mechanically and electri-
cally before shipment. It should be free of marks and scratches and in
perfect electrical order on receipt.
When unpacking, check the unit for signs of shipping damage
(damaged box, scratches, dents, etc). If there is damage to the unit or
it fails to meet specifications, notify our service department or your
local sales representative immediately. Also, call the carrier im-
mediately and retain the shipping carton and packing material for the
inspection by the carrier. We will make arrangements to repair or
replace the unit.
Remove the PCL-813 card from its protective packaging
carefully. Keep the anti-vibration package. Whenever you are not
using the board, please store it in the package for protection.
Discharge any static electricity by touching the back of the system
unit before you handle the board. You should avoid contact with
materials that create static electricity such as plastic, vinyl, and
styrofoam. The board should be handled only by the edges to avoid
static electric discharge which could damage the integrated circuits on
the PCL-813.
Warning! Discharge your body’s static electric charge by
touching the back of the grounded chassis of the
system unit (metal) before handling the board.You
should avoid contact with materials that hold a static
charge such as plastic, vinyl and styrofoam. Handle
the board only by its edges to avoid static damage to
its integrated circuits. Avoid touching the exposed
circuit connectors.
