cAutIoN
Take care not to cut the cable too short. Once cut, additional lengths of cable
cannot be added as this will invalidate the intrinsically safe certification. It is
also recommend that a loop of cable is made at the junction box to allow slack
for any future re-termination.
The enclosure of the remotely mounted sensor contains aluminum. Care must
be taken to avoid ignition hazards due to impact or friction when installed in the
Zone 1 location.
All cable entry devices and blanking elements shall be certified in type of explosion
protection flameproof enclosure "Ex e", suitable for the conditions of use and
correctly installed.
6. Mount the remote sensor junction box ensuring enough room below to fit
the sensor and weatherproof cover.
7. Attach the cable to the remote terminal box via the gland provided.
8. Make the wiring connections as shown in Figure 13.
9. Fit the terminal box lid.
10. Plug the sensor into the socket at the bottom of the terminal box.
11. Fit the sensor retainer, tighten the locking screw and fit the weatherproof cover.
