Mechanical Installation
The wall mounted housing should be installed at an easily accessible place to enable the read-
ing out of messages at every time and to ensure an easy maintenance.
Please pay attention to the indicated operation temperature for the IMC and build in transmit-
ters (
)
DB). The IMC should be installed protected against weather conditions and bigger cli-
matic fluctuations.
The dimensions for assembly and further installation dimensions can be taken from the Techni-
cal Data Sheet (
)
DB). The wall mounted housing can be opened by means of a usual two cam
lock key.
The IMC itself may not be installed in hazardous areas. The air change via ventilation of the
housing is that designed that in case of a leakage in the internal hosing the measured gas is
always that much diluted that a hazardous gas mixture cannot occur inside the housing. Due to
the rotary speed monitoring of the two fans the function of the so called "inner explosion pro-
tection" is ensured.
