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 28 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.
