3.3 Connection of electrical bus lines

3 Setting Up
OZD FIP G3 … Version 3.2 08/07
䊳
The FIP repeater should only be supplied with a
regulated
safety extra-low voltage
to IEC 950 /
EN 60 950 / VDE 0805 of +24 V -20% to max. +48 V
+10%.
䊳
To enhance operational reliability, a redundant supply
from various sources is provided. The operating
voltages can be supplied in two ways:
–
via terminal +24 V/48 V of the terminal block
–
via terminal +24 V/48 V* of the terminal block
The common negative connection in the middle of the
terminal block is indicated by ”0 V“.
䊳
The two voltages can have any (even different) values
within the specified limits of +24 V/+48 V.
䊳
If no signaling contact lines are connected to the
terminal block (see 3.5):
Secure the terminal block by screwing on the flange.

䊳
Only bus lines to the French Standard NF-C 46-604
should be used as the FIP bus line.
䊳
The electrical FIP interface (Port 1) is a 9-pole Sub-D
connector (male).
The pin assignment complies with the French
Standard NF-C 46-604
䊳
A line which is fitted with 9-pole Sub-D connectors
(female) should be used to connect data terminal
equipment. Max. length 100 m.
䊳
Termination
OZD FIP G3: The electrical port is not internally termi-
nated. The external termination must be provided in
or on the connector of the bus line in accordance with
the French Standard NF-C 46-604.
OZD FIP G3 T: The electrical port is internally termi-
nated. Therefore no termination steps are necessary .
䊳
The bus connection plug should be secured using
screws.
3.3 Connection of electrical bus lines
z
Warning!
䊳
The shielding of the Sub-D connector is made of
metal to ensure safe ground current conduction and
must therefore be conductively connected to the
shielding plate of the connector attached to the cable.
䊳
FIP bus lines must not be used to connect FIP repea-
ters to system components to which a different gro-
und potential is being applied. Voltage differences >
500 V could destroy the repeaters or cause the
system to malfunction!
䊳
FIP bus lines which are completely or partially installed
outdoors should not be connected, otherwise any
lightning strikes in the immediate vicinity could destroy
the repeaters. Optical cables should be used for bus
connections which are routed out of buildings!
