The stainless steel enclosure may be installed in a

Zone 1. Zone 2. Zone 21 or Zone 22 hazardous area; in which

case, the trunk wiring must be implemented using suitably

protected cable. It provides excellent chemical and moisture

resistance and is suitable for use in a wide range of corrosive

environments.

The 9373-FB3 fieldbus barrier enclosure is

bus-powered and requires no additional power supply in the

field. When used with a fieldbus host control system, power

for the trunk MUST be provided only by a supply conforming to

IEC 61158-2. e.g. MTL F800 or MTL 918x range of redundant

power supplies.

The enclosure is supplied pre–drilled for all trunk and

spur cable entries and internal trunking provides adequate

separation between the trunk and spur cables. It is also fitted

with Ex eb tb certified blanking plugs and a breather.
