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 re-
sult 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 Ope-
rating 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 regulations
Using fastening screws, always screw the inverter firmly to the mounting bracket to the torque specified
in the Operating Instructions.
Ensure that the fastening screws are tight before starting the inverter!
NOTE! Degree of protection IP 66 is only applicable if:
- The inverter is placed in the mounting bracket and permanently attached using screws
- The cover for the data communication area is permanently attached to the inverter with screws
Protection class IP20 applies to the mounting bracket with no inverter and venting duct!
NOTE! The solar modules connected to the inverter must comply with the IEC 61730 Class A stan-
dard.
NOTE! When photovoltaic modules are exposed to light they supply current to the inverter.
NOTE!
- Ensure that the grid neutral conductor is grounded. This may not be the case for IT grids (insula-
ted grids with no grounding); it will then not be possible to use the inverter.
- In order to use the inverter, the neutral conductor must be connected.
A neutral conductor that is too small may adversely affect the inverter feeding energy into the grid.
The neutral conductor must therefore be the same size as the other live conductors.
Observe the manufacturer's connection, Installation and Operating Instructions at all times. To reduce the ha-
zard potential to a minimum, perform all installation and connection work carefully according 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.
