MOUNTING / ELECTRICAL CONNECTION
The MSC Gas Controller is fixed to the wall through the four marked mounting points at the back side of the housing.
These mounting points are accessible after opening the housing. See figure.
The dimensions XX depend on the type and can be read on the back of the housing, in the housing version of CX, it is 115
mm.
The mounting points are covered by closing the cover at the end of the assembly.
We recommend considering the following when choosing the mounting position:
Installation height depending on the gas type, for CO2 near the ground approx. 0.3 m above floor.
Cables are introduced from above, the sensor head SC downwards.
Observe possible constructor’s instructions.
Mounting Controller:
Wiring
The technical requirements and regulations for wiring, electrical security, fire protection, as well as project specific and
environmental conditions etc. must be observed when mounting.
We recommend the following cable types
1
Power supply 230 V at least
NYM-J 3 x 1.5 mm
2
Alarm message 230 V (also possible together with power supply)
NYM-J X x 1.5 mm
2
Signal message, bus connection to DGC06, warning devices 24 V
J-Y(St)Y 2x2 x 0.8
Possibly connected external analog transmittera
J-Y(St)Y 2x2 x 0.8
1
The recommendation does not consider local conditions such as fire protection etc.
Analog sensors are connected directly to the spring type terminals of the module. The correct polarity must be observed.
Digital gas sensors are directly plugged in the connector.
The alarm signals are available as potential-free change-over contacts. If required the voltage supply is available at the
terminals L1.
The exact position of the terminals for the sensors and alarm relays is shown in the connection diagram.
