This section deals with mounting the individual MTL 9493-PS-XXX power supplies on DIN rail, for backplane mounting see Section 4. WARNING ! If this module is to be connected to intrinsically safe apparatus, it must be installed, operated and maintained only be trained competent personnel and in accordance with all appropriate international, national and local standard codes of practice and site regulation and in accordance with the instructions contained here.
3 .2 . 1 Mounting power supplies on DIN rail Clip power supplies onto type T35 DIN rail as shown in Figure 3.2, with the blue signal plugs facing towards the hazardous-area wiring. To remove an power supply from the rail, insert a screwdriver blade into the clip as shown and lever the clip gently outwards;...
Finishing Wire up individual power supplies in accordance with wiring schedules. Daisy-chain power supply connections between individual power plugs or use the power bus (see section 4.1). Segregate hazardous- and safe-area wiring into separate trunking or looms wherever possible to avoid errors and maintain a tidy installation.
3 .4 Earth rail and tagging accessories This section explains how to specify and assemble earth rail and tagging strip accessories for the MTL 9493-PS-XXX power supplies. The accessories consist of mounting brackets, earth rails, tagging strips and associated parts. They provide facilities for earthing, terminating cable screens and tagging (identifying) the positions of individual units.

3 .5 Assembly 3 .5 . 1 Fitting earth rails a) In upper position Before fitting insulating mounting blocks IMB57 , check that the swing nuts in the base of each unit are turned back into the moulding. Locate the mounting blocks on the DIN rail in the chosen position and tighten the screws (see figure 3.11).
3 .5 .3 Completed assemblies Figure 3.12 illustrates a complete assembly of MTL 9493-PS-XXX power supplies using the accessories mentioned above. The broken-line boxes either side of the assembly represent cable trunking, and the accompanying dimensions represent the minimum spacing between trunking and assemblies.
