Installation
q
Before commencing installation, ensure that the following accessory parts are available:
n
Interface cable (min. 10-pole for X.21 or 5-pole for G703.1),
n
Manual for the protection device,
n
Optical fibre cable fitted with ST-connectors at both ends,
n
Connection of the communication network,
n
This quick reference.
Before installing the CC–S
0
, ensure ESD safety!
q
The CC–S
0
is clamped onto a standard mounting rail (DIN EN 50022; 35 × 7.5).
q
Attach solid, low-resistance protective ground and operational earth on the rear panel of
the device by means of a M4 screw. The cross-section of the cable must be greater than
or equal to the cross-sectional area of any other control conductor connected to the
device. Furthermore, the cross-section of the ground wire must be at least 2.5 mm
2
(AWG 13).
q
When using the X.21–interface:
n
Insert the cable with the socket into the DSUB–connector X.21 of the CC–S
0
. In the
figure 22 you can see where the interface connector is located. The figure 25 shows
the connection assignment on the DEE connection of the CC–S
0
s.
n
Insert the other end of the cable into the communication device you have selected.
n
It is essential to ensure that the wiring between the interfaces is correct.
q
When using the G703.1 –interface:
n
With a screwdriver, connect the two core pair ends to the connection G703 of the CC–
S
0
. Connect the remaining conductor (shield) to terminal ’S’ of the connection.
n
It is essential to ensure that the wiring between the interfaces is correct.
q
Connect the transmission line of your protection device to the reception connection of the
CC–S
0
. Connect the second connection, the reception interface of your protection
device, to the transmission connection of the CC–S
0
.
q
With a screwdriver, connect the cables of the auxiliary voltage at your disposal to the CC–
S
0
. Ensure that the cable is fitted correctly.
q
The alarm relay (DR) contact can be connected as a NO contact or as a NC contact. The
NO contact is normally appropriate, so that the contact opens if the auxiliary voltage fails.
