3 INSTALLATION
The PDI-1 and PDI-2 are installed in the M Series chassis as described in Section
3.5 of the base unit operator's manual.
NOTE: The PDI-1 or PDI-2 cannot be installed as Module 1. If an PDI-1 or PDI-
2 is removed from a module slot and a different PDI-1 or PDI-2 is installed in that
location, the newly installed module acquires the previous module's configuration.
Moving an PDI-1 or PDI-2 to a different module location requires reconfiguration
because the configuration parameters are stored as a function of slot location and
module type. The configuration information does not stay with a relocated
module.
3.1 CABLING
The V79 PDI-1 and V80 PDI-2 modules each have a DC-37F connector.
Equipment connections for each module is similar. Each input of the V79 module
has a ground connection and each input of the V80 module has a return
connection. Figure 1 and Figure 2 below show the V79 and V80 connections
respectively.
