PELV Circuits

All signal and control voltages must be designed as PELV (Protective Extra Low Voltage) circuits. In particular, this implies protective measures against direct and indirect contact with hazardous voltage by:

  • Ensuring that the voltage with respect to PE (Protective earth ground) remains below 30 Vdc.

  • Ensuring separation between PELV circuits and other circuits implemented in the cabinet.

Connect GND / 0 V to PE at least at one point in the control cabinet.

Separate high and low voltage wiring and respect the standard IEC 61800-5-1, Adjustable speed electrical power drive systems - safety requirements.

 DANGER
ELECTRIC SHOCK DUE TO INADEQUATE PROTECTIVE SEPARATION
Only connect devices, electrical components, or lines to the signal voltage connectors of these products that feature a sufficient, protective separation from the connected circuits in accordance with the standards (IEC 61800-5-1: Adjustable speed electrical power drive systems - safety requirements).
Failure to follow these instructions will result in death or serious injury.
