A
Danger
to internal
components1
Voltage sources from external
circuitry must conform to the recommenda-
tions in VDE 0160, 5.88 for low-voltage
electrical separation.
Connect induc-
tive loads only with a quenching
diode parallel to the inductance.
Use only shielded
cable!
Connect the shield to the connector
housing
