Figure 3.22 DM8W Cable
(Connection to Density Detector)
Remove the cover of the terminal box, using the spanner in accessories, and insert the special cable
into the cable inlet. Connect each conductor to the respective terminals.
A fl exible fi tting is used at the inlet of the density detector (note) and the cable from the detector runs
though metal conduit to the duct. For Model VD6DF explosionproof detector, wiring should be made
complying with the Recommended Practice.
The explosionproof fl exible fi tting for wiring should be used at the cable inlet (G3/4 female) of the
detector.
(Note) The fl exible fi tting is not inevitable. The Detector not moved for usual check or maintenance
does not require the fl exible tube.
