WARNING
CAUTION
E KE A1 A2
Injury, fire and damage to property due to a short circuit
in isoHV1685D-425 and isoHR1685D-925
According to DIN VDE 0100-430, protective devices (fuses)
used to protect against short circuits when terminals L1/+
and L2/- are coupled to the IT system to be monitored can be
omitted if the wiring is designed in such a manner that the
risk of a short circuit is kept to a minimum. Ensure short-cir-
cuit-proof and earth-fault-proof wiring.
Make sure that the operating voltage is correct!
Prior to insulation and voltage tests, the ISOMETER® must be
disconnected from the IT system for the duration of the test. In
order to check the correct connection of the device, a function-
al test has to be carried out before starting the system.
