4.1.4 Installation procedure – 1/2DIN models
For Wall Mount:
– Remove rear cover from front housing.
– Start by unscrewing the four screws located on the face of the transmitter, in each corner.
This allows the front cover to swing away from the rear housing.
– Remove the hinge-pin by squeezing the pin from each end. This allows the front housing to
be removed from the rear housing
– Drill out wall-mount breakthroughs in the rear housing. This is also a good time to drill out
cable gland holes for power, sensor and interface cables.
– Mount rear housing to wall using appropriate mounting hardware for wall surface. Be sure
it is level and securely fastened and the installation adheres to any and all clearance
dimensions required for transmitter service and maintenance.
– Insert two black protective covers (supplied with the M300 transmitter) over the fixing
hardware and into the space on the inside back cover, as shown in the drawing below.
This is necessary to maintain unit integrity.
– Replace the front housing to the rear housing. The unit is ready to be wired.
For Pipe Mount:
– Use only manufacturer-supplied components for pipe-mounting the M300 transmitter
and install per the supplied instructions. See section 15 for ordering information.
