4.1.5 Installation altitude
The installation altitude is the height above sea
level of the installation site.
Products installed up to 3280 ft (1000 m) above
sea level can be loaded 100 %.
The motors can be installed up to 11,482 ft (3500
m) above sea level.
Products installed more than 3280
(1000 m) above sea level must not be
fully loaded due to the low density and
consequent low cooling effect of the
air.
The motor output power (P2) in relation to the
altitude above sea level is shown in the graph.

To maintain the galvanic isolation and ensure
correct clearance according to EN60664-1:2007,
adapt the supply voltage to the altitude.
The supply voltage for a single-phase motor in
relation to the altitude is shown in the graph.
