Devices with 230 V connection In accordance with DIN VDE 0100 part 410, section 411.1.3 attention must be paid to ensuring a safe sepa- ration between system lines and the mains voltage; i.e. system and mains cores must not be permitted to touch! The system line cable (extra-low safety voltage) must be stripped back by the minimum possible.Electrostatic chargingAs a result of electrostatic charging, direct contact with the circuit board can result in destruction of the device. Direct contact with the circuit board must therefore be avoided.
