Creating Combination Fixtures in the Field
The Federal Signal Global Series Ex de products can be connected
together in the eld using interchangeable E-box end caps and a
proprietary coupling system.
The proprietary coupling system allows for simple and cost effective,
wiring from product to product often eliminating the need for
expensive Ex wiring practices and Ex rated glands. The E-box is
available only when factory installed on an Ex d unit or when used
as a E-box spacer adjoining an existing E-box. Please refer to the
accessories listed on page 25 for available options. When creating
certain xture combinations, it is necessary to replace E-box end caps
before mounting the product. If you are creating combination xtures,
refer to instruction manual 25500259 for specic instructions and
details.
A note about combination xtures: If the product is Ex db marked
only, it is for use in gas atmospheres. If the product is Ex db e marked,
it uses the increased-safety terminal enclosures and is only for gas
atmospheres. If the product is Ex tb marked, it is for installation in
dust atmospheres.
