6.3 Cable entries
See the size of the cable entries in section 29. Other
technical data.
6.4 Cable glands
The number and size of cable glands delivered with
the pump depends on the motor size. See section
29. Other technical data.
6.5 Ensuring motor cooling
Leave at least 50 mm between the end of the fan
cover and a wall or other fixed objects. See fig. 1.

a wall or other fixed objects
6.6 Outdoor installation
If you install the motor outdoors, provide the motor
with a suitable cover and open the drain holes to
avoid condensation on the electronic components.
See figures 2 and 3.
The cover must be sufficiently large to ensure that
the motor is not exposed to direct sunlight, rain or
snow. Grundfos does not supply covers. We
therefore recommend that you have a cover built for
the specific application. In areas with high humidity,
we recommend that you connect the motor
permanently to the mains supply and activate the
built-in standstill heating function. See section
13.22 Standstill heating, page 48.

Grundfos)
6.7 Drain holes
When the motor is installed in moist surroundings or
areas with high humidity, the bottom drain hole must
be open. The enclosure class of the motor will then
be lower. This helps prevent condensation in the
motor as the motor becomes self-venting, and it
allows water and humid air to escape.
The motor has a plugged drain hole on the drive
side. You can turn the flange 90 ° to both sides or
180 °.

CAUTION
Crushing of feet
Minor or moderate personal injury
- Secure the product to a solid foundation
by bolts through the holes in the flange
or the base plate.
In order to maintain the UL mark,
additional requirements apply to the
equipment. See page 73.

When fitting a cover to the motor, observe
the guideline in section 6.5 Ensuring motor
cooling.
