Installation
During AF1 installation, take special care not to bend or contaminate the pins.
Bent or dirty pins can prevent proper AF1 programming and use. The AF1’s
transparent window is covered with the product label to avoid accidental
alteration of memory from uv light sources. Do not remove this label. Store the
AF1 in its shipping container when not installed in a Mini–PLC–2/15 processor.
The AF1 can be damaged during routine handling if proper precautions are not
taken to reduce static electricity discharges.
Recommended precautions include:
Handle the AF1 by the case without touching its pins.
Use a static free work station.
Wear a conductive wrist strap which has a minimum 200k ohms resistance
and is connected to earth ground.
Ground tools prior to contacting the AF1.
Connect static–free work station to ground through a minimum 200k ohm
resistance.
Control the relative humidity of the installation area–ideal conditions are
40% to 60% relative humidity.
The following is a list of things that should not be done:
Do not handle styrofoam, plastic, or cellophane–covered articles such as
combs, cigarette packages, and candy immediately prior to handling an AF1.
Do not hand the AF1 to someone who is not antistatic protected.
Do not install the AF1 in areas which might contaminate or foul the pins of
the AF1 device.
Do not handle the AF1 by its pins.
Do not slide the AF1 across any surface.
Do not place the AF1 in a non–conductive plastic bag.
When these precautions are followed, the potential difference between the AF1
pins is reduced thereby reducing the problems associated with static discharges.
