7. Operating conditions

7.1 Ambient temperature

7.1.1 Ambient temperature during storage and
transportation
-30 to +60 °C.

7.1.2 Ambient temperature during operation

-20 to +50 °C.
The motor can operate with the rated power output
(P2) at 50 °C, but continuous operation at higher
temperatures will reduce the expected product life.
If the motor is to operate at ambient temperatures
between 50 and 60 °C, an oversized motor must be
selected. Contact Grundfos for further information.

7.2 Installation altitude

The motor must not be installed more than
Caution
2000 metres above sea level.
Installation altitude is the height above sea level of
the installation site.
• Motors installed up to 1000 metres above sea
level can be loaded 100 %.
• Motors installed more than 1000 metres above
sea level must not be fully loaded due to the low
density and consequent low cooling effect of the
air. See fig. 3.

Warning
Before fitting add-on modules, making
connections in the terminal box or breaker
cabinet or starting fault finding, make sure
that the power supply has been switched
off for at least 5 minutes. Make sure that
the power supply cannot be accidentally
switched on.
Megging of an installation incorporating
MGE motors is not allowed, as the built-in
electronics may be damaged.
