Even when the solar inverter has been disconnected from mains and solar panels, wait until the con-
trol panel switches off. After this, it is recommended that you wait at least 5 minutes before opening,
and /or making any kind of alteration or connection to, the device.
Check that there is no voltage present before handling and performing any kind of work on the de-
vice. To verify the absence of voltage, type III measurement elements (1000 volts) must be used.
Do not perform any measurement or test when the VACON 8000 SOLAR is connected to mains or so-
lar panels.
Do not perform any kind of dielectric strength test on the VACON 8000 SOLAR. Unless the appropri-
ate process is followed, performing this test may damage the inverter module.
Appropriate personal protective equipment (PPEs) must be used:
Helmet
Safety goggles for electrical risk
Safety footwear
Electrically resistant gloves adequate for the voltage
Protective gloves against mechanical risk
Access to the photo-voltaic field is strictly prohibited!

Earthing and earth fault protection
CAUTION!
The Vacon 8000 Solar inverter must always be earthed with an earthing conductor connected to the
earthing terminal marked with
.
The touch current of Vacon 8000 Solar exceeds 3.5mA AC. According to EN62109-1, one or more of
the following conditions for the associated protective circuit shall be satisfied:
A fixed connection and
a)
the
protective earthing conductor
shall have a cross-sectional area of at least 10 mm
2
Cu or
16 mm
2
Al.
or
b)
an automatic disconnection of the supply in case of discontinuity of the
protective earthing
conductor
. See chapter 4.
or
c)
provision of an additional terminal for a second
protective earthing conductor
of the same
cross-sectional area as the original
protective earthing conductor
.
