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 PGH186 is connected using terminals L1(+) und L2(–) to a system that is live
due to its operation, the terminal
must not be disconnected from the protec-
tive earth conductor (PE). Otherwise the terminal will be at the dangerous system
voltage!
Risk of short circuit!
When the EDS3090PV is connected with test leads without integrated fuses a
short circuit may occur due to incorrect wiring. Connect the EDS3090PV with the
accompanying test lead with integrated fuses to reduce the risk of a short circuit.
