Insulation measurement
fault
Upon entry into the
ACTIVATION phase, the
acknowledge signal of the
REFU insulation measuring
instrument (at digital input
X17 pin 8) must at LOW
level. If this is not the case,
the inverter emits the “Insu-
lation 1” error.
Check the insulation of the

Insulation measurement
fault
Insulation measurements
are taken in the ACTIVA-
TION phase.
If the ISO measuring in-
strument (at digital input
X17 pin 8) fails to give posi-
tive feedback after the
maximum measuring time
has elapsed, there is an
insulation fault.
Where the LSPV 500K +
630K is concerned, the in-
sulation measuring instru-
ment is polled even during
ongoing operation.
Check the insulation of the
system.
