Decommissioning

DANGER
High electrocution
Potentially fatal voltage is applied to
the solar inverter during operation. This
potentially fatal voltage is still present
for 10 seconds after all power sources
have been disconnected.
► Always disconnect the inverter from
power before installation, open the
AC/DC isolating switch and make
sure neither can be accidentally
reconnected.
► Only the cover from the fuse section
may be removed. Never open other
parts of the inverter.
► Wait at least 10 seconds until the
capacitors have discharged.

DANGER
High electrocution
Potentially fatal voltage may be ap-
plied to the DC connections of the solar
inverter. When light is falling on solar
modules, they immediately start pro-
ducing energy. They do so, even when
the sun is not shining.
► Never disconnect the solar modules
when the solar inverter is powered.
► First switch off the grid connection
so that the solar inverter cannot
feed energy into the grid.
► Turn the AC/DC isolating switch to
position OFF.
► Make sure the DC connections can-
not be accidentally touched.
WARNING
Heavy weight
The inverter weighs about 73 kg.
► The inverter must be lifted and car-
ried by at least three people or with
an appropriate lifting equipment.
► Always use the mounting plate
delivered with the inverter.
To put the inverter out of operation, e.g. for mainte-
nance or to send it for repair, follow the instructions
below:
