per Phase (2 x 185 mm² per phase are also admissible).
■ ■
The inverter is not fitted with potential separation. This is provided by the medium-
voltage transformer.
■ ■
The maximum cable length between the inverter and the medium-voltage trans-
former must not exceed 30 meters.
■ ■
The AC connection (280V / 320V) of the inverter must meet the requirements of the
overvoltage category II. The AC-side overvoltage protection must be correspondingly
dimensioned.
■ ■
The AC connection of the inverter must be protected by an AC circuit breaker or an NH
fuse switch disconnector (see chapter 5.6).
■ ■
If you use external residual current devices (RCDs), use the type A RCDs with a
nominal fault current of at least 10 A per inverter. For PV plants with large stray cur-
rent capacities, the RCDs to be used should have a nominal fault current capacity of
at least 30 A per inverter.
