Protection of the device and the cable
Fuses must be installed to protect this device and the cables against overload and possible
damage/destruction through the electrical power supply. For data on the required fuses, see

PE connection and RCD compatibility
Depending on the functional principle, leakage current >3.5 mA
AC
or >10 mA
DC
can flow
through the protective ground conductor. Consequently, a stationary ground conductor connec-
tion in accordance with EN 61800-5-1 is required.
DANGER!
Risk of fatal injury from electrical current!
This product can cause direct and/or alternating current in the protective ground con-
ductor.
The leakage current, due to the functional principle of the device, can lead to prema-
ture triggering of the fault current protective device or generally prevent triggering of
it.
Therefore:
m
Wherever a differential current device (RCD) is used for protection in case of direct
or indirect contact, only an RCD of the type B is permitted on the power supply side
of the device.
m
Otherwise a different protective measure must be utilized, such as separation from
the surroundings by means of double or enhanced isolation, or separation from the
power supply system by means of an isolating transformer, for example.

Installation requirements with regard to EMC
NOTE!
The emission of radio frequency interference (RFI) is to a great extent dependent on
the wiring, spatial expansiveness and the arrangement of the components in the sys-
tem. Ensuring electromagnetic compatibility compliance in accordance with legal re-
quirements is therefore only possible on the completely assembled system and is
thus the responsibility of the system manufacturer or proprietor (re Art. 6, Par. 9 of
the EMVG; European EMC law).
