Fire prevention
CAUTION! Inverters and other current-carrying parts of a photovoltaic system may be damaged through 
faulty or improper installation.
Faulty or improper installation may cause overheating of cables and terminals as well as the formation 
of arcs. This could cause thermal damage, which in turn may lead to fires.
Please note the following when connecting the AC and DC cables:
- Securely tighten all terminals using the proper torque listed in the operating instructions.
- Securely tighten all grounding terminals (PE/GND) using the 
proper torque listed in the operating instructions, even for free 
grounding terminals.
- Do not overload cables.
- Check cables for damage and correct wiring.
- Follow all safety instructions, operating instructions, and any 
local connection regulations.
Always secure the inverter to the wall bracket with fixing screws 
using the torque specified in the operating instructions.
Only put the inverter into operation with the fixing screws securely 
tightened.
