Plug-In Coupling System; Notes On Safe Operation - Dehn PHE III Gebrauchsanleitung

4.3 Plug-in coupling system
The insulating sticks of PHE3... voltage detectors feature a plug-in coupling system that allows to
extend the handle of the voltage detector. The plastic plug-in coupling is self-guiding and protected
against twisting. Simply push the yellow pushbutton for assembly and disassembly and check the
assembled coupling elements for tight fit before using them. The yellow pushbutton must completely
snap into the longitudinal hole of the bushing in a form-fitting manner (see Fig. 4.3), (for the maximum
total length of the PHE3... voltage detector, please refer to chapter 5.).

4.4 Types of electrodes and test probes
The PHE3... voltage detector features an integrated test electrode with a tooth profile that allows
safe contact. The M8 female thread integrated in the tooth profile of the test electrode allows to use dif-
ferent detachable electrodes and test probes.
The electrode / test probe required for the relevant part of the installation is firmly screwed into the
upper end of the test prod. The relevant electrode / test probe must have the same nominal voltage
(nominal voltage range) as the installation to be tested.
When using test probes, check the indication of the PHE3... voltage detector under operating voltage
conditions prior to each use. Only use original DEHN test probes (see 11.1, page 17).

Only one person may operate the PHE... voltage detector during testing.
Handle / insulating stick
During testing, only contact the handle section of the PHE... voltage detector, namely the section under-
neath the hand guard
