Degree of protection
IP
Standard: IP65 according to EN 60529 (housing closed and all cable
bushings sealed)
Pollution class
2 in accordance with IEC 60664-1
Overvoltage category
III in accordance with IEC 60664-1
Installation altitude
h
Up to h ≤ 1000 m: without restrictions
The following restrictions apply to altitudes > 1000 m:
•
From 1000 m to max. 3800 m: I
N
reduction by 1% per 100 m
•
From 2000 m to max. 3800 m: To maintain protective separation
and the air gaps, and to adhere to creepage distances according
to EN 61800‑5‑1, an overvoltage protection device must be con-
nected upstream to reduce the overvoltages from category III to
category II.
