Safety

2.1 Proper usage

The inverter may only be used in grid-connected photovoltaic systems within the
permitted power range and in the permitted ambient conditions. Protection func-
tions may be impaired if the device is used improperly.

2.2 Improper usage

The inverter must not be operated in the following environments:
• in extremely warm environments with temperatures over +60 °C (output der-
ating from +50 °C),
• in dusty environments,
• in an environment where highly flammable gas mixtures can occur (potential-
ly explosive atmosphere).

2.3 Dangers during installation and commissioning

The following dangers exist during installation / commissioning of the inverter
and during operation (in case of installation errors):
• Risk of death by electrocution (both DC and AC)
• Risk of fire due to short-circuit
• Damage to any of the constructional fire safety measures present in the build-
ing due to incorrectly installed cables
• Damage to the inverter and connected devices or components if used in am-
bient conditions other than those permitted, if an inappropriate power sup-
ply is used (on either the direct or alternating current sides) and if devices or
components which are not permitted are connected.

2.4 Notes on installation

The following instructions must be observed during installation and operation:
• All safety regulations apply when working on the mains supply. The inverter
may not be opened.
• When laying cables, ensure that no damage occurs to any of the
constructional fire safety measures in the building.
• Make sure that the permissible ambient conditions at the installation site are
not exceeded.
• Factory labels and markings may not be altered, removed or rendered
unreadable.
• Before connecting the device, make sure that the power supply (both DC and
AC) matches the specifications on the type plate.
• Make sure that all devices which are connected to the inverter conform to the
technical data of the inverter.
• Secure the device against unintentional start-up.
• Installation work on the inverter may only be carried out when it is discon-
nected from the grid and the photovoltaic generator.
• Protect the inverter against overloading and short-circuiting.

2.5 Dangers during operation

Warning
Danger, hot surface!
The surface temperature of the casing can exceed +70 °C.
