6.8 EMC (Electromagnetic compatibility)
This is a class A unit and can cause radio interference in residential areas; if it does, the
owner/managing operator may be required to implement suitable measures and pay for
loss or damage.
Only shielded conductors may be used as connecting conductors. This applies both to
the data line and to all other conductors too.
The data lines must be stranded in pairs. Example 2 x 2 x 0.75 mm² LIYCY TP.
As far as possible, separate conductors should be used for power supply and data
6.8.1 Voltage supply (DC variants)
A regulated mains adapter with an output of at least 2 A must be used as power supply. It
is not permitted to fall below or exceed the power supply of DC 24 V ± 10 % at the
installation site. The voltage drop on the supply line must be observed and corrected
where necessary. The voltage drop in the DC variant of the supply line is calculated with
the following formula:
∆U
Voltage drop on the supply line at power supply
voltage of DC 24 V
Max. 2.4 V
∆U
Voltage drop on the supply line with maximum
permissible mains adapter overvoltage
DC 24 V +10 % (26.4 V)
Max. 4.8 V
(until 10 % unde
rvoltage is
achieved)

If the voltage drop cannot be balanced out or the calculation produces excessive cable
cross-sections, a separate mains adapter must be installed near the installation site.
Example: pressure-tight encapsulation or ex-free area on the outside of the building.
As a result of the connection of the power supply to the POLARIS, the earth for the
power supply is connected to the PE. It is essential to ensure that the earth for the
power supply on the POLARIS, if this is no
t electrically isolated, indicates no potential
difference to the PE/PA.
