Installation and Operating Instructions V04 24
5.4.5 Overvoltage category
The inverter can be deployed in grids of installation category III or lower, as defined
under IEC 60664-1. This means that it can be permanently connected at the
grid-connection point in a building. In installations involving long outdoor cable routing,
additional overvoltage-reducing measures must be taken so that the overvoltage
category is reduced from IV to III.
5.4.6 Rating of AC circuit breaker
No consumer load should be applied between AC circuit breaker and the inverter.
Use dedicated AC circuitbreakerwith load switch functionality for load switching.
The selection of the AC circuit breaker rating depends on the wiring design (wire
cross-section area), cable type, wiring method, ambient temperature, inverter current
rating etc. Derating of the circuit breaker rating may be necessary due to self-heating
or if exposed to heat.
The maximum output current of the inverters and recommended AC circuit breaker
can be found in the following table.

Danger to life due to fire
You must safeguard each inverter with an individual AC circuit breaker
in order that the inverter can be disconnected safely.
