External power supply for the control unit (XPOW)
The control unit is powered from a 24 V DC, 2 A supply through terminal block XPOW.
Using an external supply is recommended if
•
the control unit needs to be kept operational during input power breaks, for example,
because of continuous fieldbus communication
•
immediate restart is needed after a power break (that is, no control unit power-up delay
is allowed).

DI6 as a PTC sensor input
PTC sensors can be connected to this input for motor temperature measurement as follows.
The sensor can alternatively be connected to FEN-xx encoder interface module. At the
sensor end of the cable, leave the shields unconnected or ground them indirectly via a
high-frequency capacitor with a few nanofarads, for example 3.3 nF / 630 V. The shield can
also be grounded directly at both ends if they are in the same ground line with no significant
voltage drop between the end points. See the firmware manual of the inverter unit for
parameter settings.

WARNING!
As the inputs pictured above are not insulated according to IEC 60664, the
connection of the motor temperature sensor requires double or reinforced insulation
between motor live parts and the sensor. If the assembly does not fulfill the
requirement, the I/O board terminals must be protected against contact and must
not be connected to other equipment or the temperature sensor must be isolated
from the I/O terminals.

AI1 or AI2 as a Pt100, Pt1000, PTC or KTY84 sensor input
Sensors for motor temperature measurement can be connected between an analog input
and output, an example connection is shown below. (Alternatively, you can connect the
KTY to an FIO-11 or FAIO-01 analog I/O extension module or FEN-xx encoder interface
module.) At the sensor end of the cable, leave the shields unconnected or ground them
indirectly via a high-frequency capacitor with a few nanofarads, for example 3.3 nF / 630 V.
The shield can also be grounded directly at both ends if they are in the same ground line
with no significant voltage drop between the end points.
