6.8 Outdoor installation
When you install the motor outdoors, provide the motor with a
suitable cover to avoid condensation on the electronic
components. See fig.
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 enable the built-in standstill heating
function.

Examples of covers
7. Electrical installation
Carry out the electrical connection according to local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
7.1 Protection against electric shock (indirect contact)
Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.
7.1.1 Protection against mains voltage transients
The motor is protected against mains voltage transients in
accordance with EN 61800-3.
7.1.2 Motor protection
The motor requires no external motor protection. The motor
incorporates thermal protection against slow overloading and
blocking.
Note
In order to ensure sufficient cooling of the motor, the
distance (D) between the end of the fan cover and a
wall or other fixed objects must always be at least 50
mm (irrespective of motor size). See fig.

supply cannot be accidentally switched on.
Connect the motor to an external all-pole mains
switch according to local regulations.
Earth and protect the motor against indirect contact
in accordance with local regulations.
If the power supply cable is damaged, it must be
replaced by the manufacturer, the manufacturer's
service partner or a similarly qualified person.
Note
The user or the installer is responsible for the
installation of correct earthing and protection
according to local regulations. All operations must be
carried out by a qualified electrician.
