ischarge (ESD) precautions. As a minimum you
must use anti-static devices such as wrist straps and floor mats and leave modules in their anti-
static bags until they are ready to be installed.
Before proceeding to make connections to the Analog PLC Module, ensure that all the modules
in the chassis are correctly seated:
1)
Remove the front panel to the HPS/RFL GARD Pro system chassis
2)
Using minimal force, remove and re-seat all front panel modules.
Typically, when a single PLC module set is used they are installed in a 3U chassis, however if
more than one PLC is required a 6U chassis is needed. Depending on the configuration and
power consumption limits a second power supply may be required. Details on external
connections to a second power supply are shown in
Module as it would appear in the rear of a 3U chassis.
