Installing the INSUM Interface, CI857/TP853 Section 2 Installation

Installing the INSUM Interface, CI857/TP853
The CI857 is powered from the processor unit via the CEX-bus and requires
therefore no additional external power source.
Use the following procedure to install the CI857/TP853:
1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail
on page 49 and Installing the PM8xx/TP830 Processor Unit in Single
Configuration on page 56.
2. Connect the Ethernet twisted pair cable to the COM1 connector on the
baseplate (COM2 is not used for connection to INSUM).
3. Connect the other end of the Ethernet cable to the INSUM equipment via
Ethernet/LON Gateway.
Ethernet Twisted Pair Connection
The Ethernet twisted pair is connected via the 10 Base-T RJ45 connector located on
TP853. For a description of the connector see Table 8 on page 62.
Installing the CEX-bus
The CEX-bus, used for connection of communication interfaces to the processor
unit, is located on the left-hand side of the processor unit baseplate (TP830).
A bus termination unit must always be fitted to the last unit on the CEX-bus, as
shown in Figure 13 on page 58. A TB850 male CEX-bus termination unit is
supplied with each PM8xx/TP830 processor unit.
However, should the configuration require the use of a TK850 extension cable, as
shown in Figure 14 on page 59, then a TB851 female CEX-bus termination unit is
required and must be fitted to the last baseplate in the sequence. A TB851 female
CEX-bus termination unit is supplied with each TK850 extension cable.
TK850 CEX-bus Extension Cable
Only one TK850 CEX-bus extension cable may be used in any one CEX-bus. Cable
length: 0.7 m (2.3 in).
