This manual describes the installation and use of the
•
MTL SUM5 range of MTL4 universal IO modules
The MTL4 range products are intended not only for protection of hazardous
areas in process plants that apply Intrinsic Safety techniques, but are also for use
in safe-area applications.
The two application types are distinguished by the colour of the module base:
•
Blue – is used for intrinsic safety applications
•
Grey – is used for safe area applications
To ensure both the segregation of equipment and the requisite separation of wiring,
operation and maintenance activities, these two types of module base MUST NOT be
mounted on the same backplane.
The use of separate backplanes for I.S. and non-I.S. signals when installing the
different application types ensures the segregation of I.S. and non-I.S circuits.
