5.3 Accessories in enclosures
Apart from mounting, there are some other installation details which should be considered before
adding the appropriate interface modules and making the necessary cabling connections.
A range of accessories is available to accompany the MTL5500 units (see section 4) and the
following points should be observed.
5.3.1 Insulating mounting block (IMB57)
A pair of these can be attached to the DIN rail, at either end of the modules, to provide a mounting
for earth rails. Use of mounting blocks will reduce the space available for isolator modules.
5.3.2 Earth rails (ERL7)
Earth rail is produced in 1 metre lengths and will require cutting to length before mounting. ERL7
earth rails can be mounted either side of the modules but are typically mounted on the hazardous
side of the DIN rail.
5.3.3 Tagging strip (TAG57 and TGL57)
Tagging strip is produced in 1 metre lengths and will require cutting to length before mounting.
Similarly, the labels will require cutting to fit the tagging strip.
5.4 IS warning label
A 'Take Care' IS warning label is provided inside each enclosure. This should be attached to the inside
of the transparent lid when its orientation has been established.
