Figure 19. Connecting Hazardous Voltage Inputs


  1. Power off the RM-26999 and the system you are connecting to the RM-26999 for measurement.
    Caution You must de-energize the system before you connect it to the RM-26999 for measurement. Follow all workplace safety requirements for powering down hazardous voltage systems based on the applicable codes and standards in your location.
    Attention Vous devez mettre le système hors tension avant de le connecter au RM-26999 pour prendre des mesures. Respectez toutes les exigences de sécurité sur le lieu de travail concernant la mise hors tension des systèmes à tension dangereuse en fonction des normes et des codes locaux en vigueur.
  2. Connect one of the functional earth terminals to the drain wire on the twisted, shielded cable pair.
  3. Connect the twisted, shielded cable pair to the pair of hazardous voltage ports.
  4. Power on the RM-26999 and the system you are connecting to the RM-26999.
  5. Verify the corresponding hazardous voltage input status LED is on, if applicable.
    Note The hazardous voltage input status LED lights if a hazardous voltage above 50 V DC or 40 V AC 60 Hz has been applied to the corresponding input channel.
