Screwing The Test Prod In Place - Dehn PHE III Gebrauchsanleitung

Note :
When assembling PHE3... voltage detectors, only use the single parts shown on the rating plate of the re-
levant PHE... voltage detector (see rating plate of the PHE3..., chapter. 5, page 8).

4.1 Screwing the test prod in place

When attaching / removing test prods with rain cap, no
mechanical forces may act on them.
Ensure tight fit of the assembled elements.
Before screwing the test prod in place, check the sealing
ring (O-ring) on the screw-in element
prod for good order and condition and perfect fit.
Replace worn out sealing rings (DEHN Part No. 767
779).
4.2 Indicators
Two different types of indicators are available for
PHE3... voltage detectors.
4.2.1 Indicators with universal gear coupling
Only use insulating sticks of the same coupling type
(universal gear coupling) for indicators with universal
gear coupling!
Assembly
Plug the indicator with universal gear coupling into the
coupling element of the insulating stick and tighten the
knurled screw.
Ensure that the teeth engage with one another.
The inclination angle can be adjusted ± max. 30° (see
Fig. 4.2.1).
4.2.2 Indicators with M12 threaded pin
Only use insulating sticks of the same coupling type
(M12 threaded bushing) for indicators with M12
threaded pin!
Assembly
Place the indicator with M12 threaded pin above the
coupling element (M12 threaded bushing) of the insula-
ting stick and screw it hand-tight (see Fig. 4.2.2)
