Installation
During AF4 installation, take special care not to bend or contaminate the pins.
Bent or dirty pins can prevent proper AF4 programming and use. The AF4’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 AF4 in its shipping container when not installed in a Mini-PLC-2/15
processor.
The AF4 can be damaged during routine handling if proper precautions are not
taken to reduce static electricity discharges.
Recommended precautions include:
Handle the AF4 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 AF4.
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 AF4.
Do not hand the AF4 to someone who is not antistatic protected.
Do not install the AF4 in areas which might contaminate or foul the pins of
the AF4 device.
Do not handle the AF4 by its pins.
Do not slide the AF4 across any surface.
Do not place the AF4 in a non-conductive plastic bag.
