In order to prevent operating malfunc-
tions, it is recommended, that the oper-
ating personnel discharge themselves
prior to touching communication con-
nectors or perform other suitable
measures to reduce effects of electro-
static discharges.
The connectors between the Terminal
Bases and Processor Modules or
Communication Modules must not be
touched during operation. The same is
valid for the I/O-Bus with all modules
involved.
