When these precautions are followed, the potential difference between the AF4
pins is reduced thereby reducing the problems associated with static discharges.
The AF4 fits into a 28-pin ZIF (zero insertion force) socket, which is located
under a hinged door at the lower side of the Mini-PLC-2/15 processor
(Figure 2.1).
