Special mounting hardware is available for mounting a

Model 244EH head mount transmitter to a DIN rail, or assembling a new Model 244EH to an existing threaded sensor connection head (former option code L1).

Mounting a Model 244EH to a DIN Rail

To attach a head mount transmitter to a DIN rail, assemble the appropriate rail mounting kit (part number 00644-5301-0010) to the transmitter as shown in Figure 2-3,then follow the procedure under “Rail Mount Transmitter with Integral Mount Sensor” on page 2-7.

Note: Kit includes Mounting Hardware and both types of rail kits.

Retrofitting a Model 244EH for Use in an Existing Threaded Sensor Connection Head

To mount a Model 244EH in an existing threaded sensor connection head (former option code L1), order the Model 244EH retrofit kit (part number 00644-5321-0010). The retrofit kit includes a new mounting bracket and all associated hardware necessary to facilitate the installation of the Model 244EH in the existing head.
