(4) Fit and connect the field wiring.
See the subsequent tables and diagram for wiring details. Use either:
Conduit - using one or both of the ¾ NPT conduit entries. Ensure that a conduit sealing fitting
is installed within 18" of the enclosure on all conduit runs.
Cable - using any suitable flameproof cable entry device certified as Equipment to Directive
94/9/EC (ATEX).
Notes:
1. All unused cable/conduit entries must be sealed with a certified sealing plug (one plug is
supplied fitted).
2. For a multi-sensor system using a network loop, both cable/conduit entries are used, one
bringing the loop connections in and the other taking them out of the box. Remove the fitted
certified sealing plug from the spare cable/conduit entry.
