Important Note - Eaton Crouse-Hinds Series Instruction Manual

This manual describes the installation and use of:
• MTL4500 range of isolating interfaces for Intrinsic Safety
• MTL4600 range of signal conditioners
The MTL4500 range of products are intended for protection of hazardous areas in process
plants that apply Intrinsic Safety techniques.
Although functionally similar to the MTL4500 range, the MTL4600 range of isolator
modules are NOT certified or approved for connection to hazardous area circuits.
To ensure both the segregation of equipment and the requisite separation of wiring,
operation and maintenance activities, it is recommended that the MTL4500 and the
MTL4600 range of modules are NOT mounted on the same backplane.
The use of separate backplanes for I.S. and non-I.S. signals reduces the possibility of
confusion over 'safe operating practice' and is strongly recommended.
ATEX
If the country of installation is governed by the Essential Health and Safety
Requirements (Annex II) of the EU Directive 2014/34/EU [the ATEX Directive - safety of
