Mounting FPM modules to the front plate
Refer to Figure 2 - PRCAB + FPM, page 20.
The front-plate modules (FPMCPU, FPMNUL, FPMLED, FPMLEDPRN, FPMEXT) can be mounted to one of the
apertures on the cabinet front plate. The FPMCPU module can also be mounted to front plate of the PRREP
repeater enclosure.
1.
Align the 6 holes on the module frame (paragraph 2 - [H]) with the 6 holes on the cabinet front-plate or
repeater enclosure.
2.
Secure the module in place by fastening the supplied screws into the aligned holes.
3.
Connect the CAN BUS wire ([A] supplied):
- if the module is mounted in the upper aperture, the CAN BUS wire must be connected between the
module port ([B], paragraph 2 - [N]) and the CAN bar port ([C])
- if the module is mounted in the lower aperture and another module is mounted in the upper aperture, the
CAN BUS wire must be connected between module port ([D], paragraph 2 - [N]) and the appropriate port
on the upper module ([E], paragraph 2 - [O])
4.
Fit the ferrite ([F], supplied) to the connected CAN BUS cable.
5.
In the case of an FPMCPU module, complete the wiring on the LAN cable and BUS (refer to paragrafo 4).

Module wiring - repeater connection
The wiring for the FPMCPU module provides for a connection to the Ethernet network via LAN cable and to the
RS485 BUS which must be set up between the Previdia Max control panel and the system repeaters.
The connection to the Ethernet network is obtained through the LAN port on the module (paragraph 2 - [M]).
Cables:
UTP cable with RJ45 connectors
Protected by ferrites (supplied)
Compliant with local laws and regulations in force
The BUS connection is achieved through the RS485 communication port on the module PCB (paragraph 2 -
[P]). Two connection methods are possible, depending on whether the power supplied to the control panel is
sufficient enough to power the repeaters, due to the loads required or the length of the cables.
Cables:
4 wire shielded cable
Maximum length (from control panel to last repeater) 1000m
Protected by ferrites (supplied)
