2.9 Electromagnetic compatibility

Note
Enabling button not effective
The enabling button is only effective if the HMI device is logged onto the effective range and
the "RNG" LED on the HMI device lights up.
If the operator leaves the effective range, the enabling button is deactivated after 5 seconds.
After 30 seconds the "Effective range exited without logoff" dialog box opens. The
LED "RNG" only goes out when the operator has confirmed this dialog box.
Risk from improper use
To avoid the danger of unauthorized use of the enabling button due to impermissible hold-
down, on each project start the enabling button must be pressed all the way down, and then
released.
2.9 Electromagnetic compatibility
Introduction
The HMI device, the charging station, the transponder, and the power supply satisfy, among
other things, the requirements of the EMC laws pertaining to the European domestic market.
The enhanced testing and limit value levels defined by CDV 61326-3-1/Ed. 1 have been
taken into account during the type test
EMC-compliant installation
Conditions for fault-free operation include EMC-compatible assembly of the charging station
and the use of interference-proof cables. The "Directives for interference-proof installation of
PLCs" and the "SIMATIC NET, Fundamentals of Industrial WLAN" manual also apply to the
assembly of the charging station.
