Danger to internal components!

The power supply of external circuits must comply with
EN 50178 requirements for low voltage electrical
separation

.

Connect inductive loads only with a quenching diode
parallel to the inductance

.

Danger to internal components!

Use only shielded cables and connect the shield to the
connector housing
