Installation
Before commencing installation, ensure that the following accessory parts are available:
Interface cable, screened (4-core for the E1 / T1 interface),
Manual for the protection device or the other serial device
,
Optical fibre cable fitted with ST–connectors at both ends,
Connection of the communication network,
This Manual.
Before installing the CC–2M, ensure ESD (
E
lectro
s
tatic
D
ischarge) safety!
The CC–2M is clamped onto a standard mounting rail (DIN EN 60715; TH 35–7.5).
Attach solid, low–resistance protective ground and operational earth on the rear panel of
the device by means of a M4 screw. It is located on the right above the power supply
voltage terminals. 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. Further-
more, the cross–section of the ground wire must be at least 2.5 mm
2
(AWG 13).
Connection of the E1 / T1 interface:
With a screwdriver, connect the two core pair ends to the connection E1 / T1 of the
CC–2M. Connect the remaining conductor (screen) to terminal “S” of the connection.
Attach and earth the screening on both sides.
It is essential to ensure that the wiring between the interfaces is correct.
A screened cable is recommended (see also signal connection).
Connect the transmission line of your protection device (fibre optic) to the reception
connection of the CC–2M. Connect the second connection, the reception interface of
your protection device (fibre optic), to the transmission connection of the CC–2M.
With a screwdriver, connect the cables of the auxiliary voltage at your disposal to the
CC–2M. Ensure that the cable is fitted correctly.
The alarm relay GOK (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.
