EN 60529 IP 20
NEMA 250 Protection against contact in
accordance with type 1
EN 61800−5−1 Overvoltage category III
from 2000 m amsl: external measures for complying with
the overvoltage category II are required, e.g.
l connecting isolating transformer upstream
l connecting overvoltage protection system upstream
EN 61800−5−1 up to 2000 m amsl:
Safe mains isolation by double/reinforced insulation for
mains with neutral earthing with a rated voltage for the
external conductor/star point up to 300 V.
from 2000 m amsl:
If an overvoltage protection system is connected upstream,
additional external separating measures are required for
maintaining the safe mains isolation.
EN 61800−5−1 DC−bus connection: Not short−circuit−proof
