Connecting the locating current injector

28

EDS309x_D00012_03_M_XXEN/11.2014

5.3   Connection to a live IT system

Connect the locating current injector PGH18… as follows:

Risk of electric shock!

On touching live uninsulated conductors, death or serious injury may be caused.
For this reason prevent any physical contact with active conductors and follow
the rules for working on electrical systems.

Risk of electric shock!

If the PGH18… is connected using terminals L1, L2, L3 (or L1, L2) to a system that
is live due to its operation, the terminal 

must not be disconnected from the

protective earth conductor (PE). Otherwise the terminal will be at the dangerous
system voltage!
