6.12 Practical usage
6.12.1 Insulation fault location in a system without a permanently installed EDS system
The EDS309… is primarily used as a portable insulation fault location system in unearthed IT sys-
tems. Once all the instructions in chapter “Considerations prior to use” on page 19 have been fol-
lowed, insulation fault location can be started. Proceed as follows during this process:
1. Check whether the system voltage is within the permissible limits.
The permissible voltages are stated in the user interface on the PGH18….
2. Connect the locating current injector PGH18… close to the feed, see connection diagram on
page 28. During this process follow the general guidelines for working with electrically live sys-
tems!
– First connect the PE socket on the PGH18… to the system's PE using the green-yellow wire.
– Then connect the PGH18… to the system to be checked using the connection wires pro-
vided.

Risk of electric shock!
On touching live uninsulated conductors, death or serious injury may be caused.
For this reason avoid any contact whatsoever with active conductors on con-
necting the PGH and positioning the measuring clamp.
