However the measurement on the DC disconnector must be carried out at the screws and
not at the contacts.

Measurement should only be carried out once the insulation resistance test has been
passed.
-
Mount the inverter lid again.
-
Only successful measurement between the lid and mounting bracket guarantees that
the ground conductor function of the inverter is working.
-
Ensure the device to be checked has been securely disconnected from the AC grid
(grid power line [L and N] must not be connected). If the AC grid cannot be disconnect-
ed from the mounting bracket, the appropriate safety precautions must be taken.
-
Re-insert the inverter in the mounting bracket.

WARNING!
An electric shock can be fatal. Capacitors may become charged
during the insulation resistance measurement. After the insulation resistance test,
all tested potentials must be checked to ensure it is de-energized before the safe-
ty inspection can be continued. Alternatively, the capacitors can be discharged by
short-circuiting the tested potentials or using the discharge function on the insu-
lation tester.
CAUTION!
Take safety precautions. Observe the safety rules – DC voltage pres-
ent!
WARNING!
Set DC disconnector of the inverter to level 0 and insert the inverter
in the mounting bracket. Installing the inverter means that voltage is now also
present at the inverter.
