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 miniature circuit-breaker
No load should be applied between the circuit-breaker and the inverter. Use dedicated
circuit-breakers with load switch functionality for load switching. The selection of the
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 currents of the inverters can be found in the following table.

Danger to life due to fire
• You must protect each inverter with an individual miniature circuit-
breaker in order that the inverter can be disconnected safely.
