3.3 Cable Entries
3.3.1 Typical Cable Entries and Connections
A typical XN3 enclosure is supplied with entries and connectors as shown in Figure
3.
• Connections A-D are INTRINSICALLY SAFE outputs providing galvanically
isolated RF signals (see Section 3.10 for details), carried on conventional 50Ω
impedance N-type female connections. The N-type connections are the front
part of the bulkhead which transit through the enclosure and are approved as
part of the XN3 ATEX/IECEx certification.
• Apply suitably assessed glands to cable entries (marked E and F) as appropriate
with at least 5 threads engaged.
o
Thread maximum size is M25x1.5 or 3/4 ” NPT depending on customer
specification.
o
Up to one threaded adaptor per entry.
o
If a threaded NPT adaptor is fitted, for example a CMP 737DRM2T15,
then review this component’s datasheet for any specific instructions.
• The position and configuration of cable entries and connections can vary
depending on the XN3 ordered. Mark off connections inside the junction box.
