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 Appendix.

4.3 Cable entries
See the size of the cable entries in section
data.
4.4 Ensuring motor cooling
Leave at least 2 inches (50 mm) between the end of the fan cover
and a wall or other fixed objects. See fig. 1.

4.5 Outdoor installation
If you install the motor outdoors, provide the motor with a cover
and open the drain holes to avoid condensation on the electronic
components. See figures
2
and 3.
When fitting a cover to the motor, observe the
guidelines in section
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

4.6 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 °.

5. Electrical installation
DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply to the motor and to the
signal relays. Wait at least 5 minutes before you
make any connections in the terminal box. Make
sure that the power supply cannot be accidentally
switched on.
DANGER
Electric shock
Death or serious personal injury
- Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
If the power supply cable is damaged, it must be replaced by the
manufacturer, the manufacturer's service partner or a similarly
qualified person.
The user or the installer is responsible for the installation of
correct grounding (earthing) and protection according to local
regulations. All operations must be carried out by a qualified
electrician.
Carry out the electrical connection according to local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
