Installation

There are two particular aspects of safety that must be considered when installing the MTL4500 or

MTL5500 modules and these are:

• Functional safety

• Intrinsic safety

Reference must be made to the relevant sections within the instruction manual for MTL4500 range

(INM4500)or MTL5500 range (INM5500) which contain basic guides for the installation of the interface

equipment to meet the requirements of intrinsic safety. In many countries there are specific codes of

practice, together with industry guidelines, which must also be adhered to.

Provided that these installation requirements are followed then there are no additional factors to meet

the needs of applying the products for functional safety use.

To guard against the effects of dust and water the modules should be mounted in an enclosure providing

atlea st IP54 protection degree, or the location of mounting should provide equivalent protection such as

inside an equipment cabinet.

In applications using MTL4500 range, where the environment has a high humidity, the mounting

backplanes should be specified to include conformal coating.
