1. General description
The SM 111 is used for the collection and transfer of
sensor data. The SM 111 works together with the
IO 111* as shown below.
Fig. 1 IO 111 and SM 111
* Only IO 111 versions with communication module,
part number 96177804.
The SM 111 can collect data from
• 2 current sensors, 4-20 mA
• 1 water-in-oil sensor
• 3 Pt100 thermal sensors
• 1 Pt1000 thermal sensor
• 1 PTC thermal sensor
(maximum 3 PTC sensors in series)
(According to DIN 44081/44082)
• 1 digital input.

3. Installation
The SM 111 must only be installed by Grundfos or an
authorized service workshop.
3.1 Electrical connection
Before installation, check that the SM 111 has not
been damaged during transportation.
3.2 EMC-correct installation
It is especially important to ensure an EMC-correct
installation of pumps with frequency converter.
The following rules must be observed:
• Connect the cable screen to earth.
• Do not twist screen ends, as this will destroy the
screen effect at high frequencies. Use cable
clamps as shown in fig. 2.
• It is important to ensure a good electric contact
from the mounting plate through the mounting
screws to the metal cabinet of the frequency
converter.
• Use toothed washers and a galvanically
conducting mounting plate.
