2. Abbreviations and definitions 3. General information
These installation and operating instructions apply to the
Grundfos TPE, TPED, NKE, NKGE, NBE and NBGE pumps.
The pumps are fitted with frequency-controlled
permanent-magnet motors for single-phase or three-phase mains
connection.
3.1 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 39.
This product can communicate with the Grundfos GO Remote
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.
3.2 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.
4. Mechanical installation
4.1 Mounting
The pump must be secured to a solid foundation by bolts through
the holes in the flange or the base plate.
4.2 Cable entries
The motor has four M20 screwed cable entries fitted with blind
plugs from factory.
The following cable glands are included:
• 2 x M20 cable gland, cable diameter ∅5 mm
• 1 x M20 cable gland, cable diameter ∅7-14 mm.
AI Analog input.
AL Alarm, out of range at lower limit.
AO Analog output.
AU Alarm, out of range at upper limit.
Current sinking
The ability to draw current into the terminal and
guide it towards GND in the internal circuitry.
Current
sourcing
The ability to push current out of the terminal
and into an external load which must return it
to GND.

Note
Some variants of these products and all products
sold in China and Korea have no possibility of
radio communication according to local
legislation.
Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Note
In order to maintain the UL mark, additional
installation procedures must be followed.
