Installation

Before commencing installation, ensure that the following accessory parts are available:
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
Connection of the E1 / T1 interface:
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.
