Fire prevention
CAUTION! Risk of damage to inverters and other live photovoltaic system components due
to poor or unprofessional installation.
Poor or unprofessional installation can cause overheating of cables and terminal connections
and result in arcs. These can cause heat damage, which in turn may lead to fires.
Observe the following when connecting AC and DC cables:
- Tighten all terminals to the torque specified in the Operating Instructions
- Tighten all grounding terminals (PE / GND), including free ones, to the torque specified
in the Operating Instructions
- Do not overload cables
- Check cables for damage and verify that they are laid correctly
- Take note of the safety instructions, Operating Instructions and any local connection re-
gulations
Using fastening screws, always screw the inverter firmly to the mounting bracket to the tor-
que specified in the Operating Instructions.
Ensure that the fastening screws are tight before starting the inverter!
NOTE! Protection class IP65 is only applicable if the inverter is permanently attached to the
mounting bracket with screws.
Protection class IP20 applies to the mounting bracket with no inverter or venting duct.
NOTE! The solar modules connected to the inverter must comply with the IEC 61730 Class
A standard.
NOTE! When photovoltaic modules are exposed to light they supply current to the inverter.
NOTE! If the cable insulation of the AC cable is not designed for a maximum of 1000 V, AC
and DC cables must not be crossed when connecting in the inverter.
If crossing the cables during connection is unavoidable, the AC cable must be laid in one pi-
ece of the protective hose supplied with the inverter.
AC and DC cables can only be laid together if the insulation on both cables is designed for
the max. possible voltage of 1000 V.
Observe the manufacturer's connection, Installation and Operating Instructions at all times. To re-
duce the hazard potential to a minimum, perform all installation and connection work carefully ac-
cording to the instructions and regulations.
Refer to the device Operating Instructions / Installation Instructions for the tightening torques to
be used at the relevant terminal connections.
