Protection devices

• Manufacturer's declaration: The devices are equipped with an integrated protection device against short circuit. The switch-off times of the inverters are max. 100 ms and are therefore well below the switch-off times required by the standards.
• The power contactor of the supply system cable must be realized through external overload devices.
• The relevant standards must be observed concerning the cable cross section, the voltage drop, and the type of routing that is used.
