7.3 Installation altitude

The motor must not be installed more than 6562
Caution
ft (2000 m) above sea level.
Installation altitude is the height above sea level of the installation
site.
• Motors installed up to 3281 ft (1000 m) above sea level can be
loaded 100 %.
• Motors installed more than 3281 ft (1000 m) above sea level
must not be fully loaded due to the low density and
consequent low cooling effect of the air. See fig. 13.

7.4 Air humidity

Maximum air humidity: 95 %.
If the air humidity is constantly high and above 85 %, one of the
drain holes in the drive-end flange should be open. See section
5. Mechanical installation.

7.5 Motor cooling

To ensure cooling of motor and electronics, observe the following:
• Position the motor in such a way that adequate cooling is
ensured. See section 5.3 Ensuring motor cooling.
• The temperature of the cooling air must not exceed 122 °F
(50 °C).
• Keep cooling fins and fan blades clean.
