2. Abbreviations and definitions 3. General information
These installation and operating instructions are a
supplement to the installation and operating
instructions for the corresponding standard pumps
TP, TPD, NB, NBG, NK and NKG. For instructions not
mentioned specifically in this manual, see the
installation and operating instructions for the
standard pump.
4. General description
The pumps are fitted with frequency-controlled
permanent-magnet motors for single-phase or
three-phase mains connection.
4.1 Radio communication
This product incorporates a radio module for remote
control which is a class 1 device and can be used
anywhere in the EU member states without
restrictions.
For use in USA and Canada, see page 71.
Some variants of the product and products sold in
China and Korea have no radio module.
This product can communicate with Grundfos GO
and other products of the same type via the built-in
radio module.
In some cases, an external antenna may be
required. Only Grundfos-approved external antennas
may be connected to this product, and only by a
Grundfos-approved installer.
4.2 Battery
Pumps fitted with the advanced functional module,
FM 300, incorporate a Li-ion battery. The Li-ion
battery complies with the Battery Directive
(2006/66/EC). The battery does not contain mercury,
lead and cadmium.
