3 Installation and Removal
3.1 Fitting the unit onto a DIN rail
The LM Technic processor is designed to be mounted onto a standard DIN rail.
To install the unit:
1) Ensure that a suitable DIN rail (DIN EN 50 022) is available and installed
correctly (refer to Appendix).
2) Refer to Fig. 3. Rest the uppermost groove on the rear of the processor
on the top lip of the DIN rail.
3) Push the bottom of the unit so that the sliding spring catch clips onto the
DIN rail.
3.2 Removing the unit from a DIN rail
1) Refer to Fig. 4. Insert a screwdriver into the sliding spring catch via the
slot on the underside of the unit.
2) Lever the sliding spring catch downwards so that it disengages from the
DIN rail.
3) Lift the processor off the DIN rail.
3.3 Electrical connections
The LM Technic processor is designed to be used in conjunction with the Land
DPU Power Supply Unit.
To prevent damage to the equipment, ensure that the DPU (power supply)
and signal processor are fully interconnected, before switching on the mains
power supply.
The LMT to DPU wiring interconnections are given in Fig. 5 (overleaf).
The LMT wiring schedule is given in Table 1.
The DPU wiring schedule is given in Table 2.
Connections to the configuration port are given in Table 3 - Appendix B.
