Icons

  • Notice—Take precautions to avoid data loss, loss of signal integrity, degradation of performance, or damage to the model.
  • Caution—Take precautions to avoid injury. Consult the model documentation for cautionary statements when you see this icon printed on the model. Cautionary statements are localized into French for compliance with Canadian requirements.
  • Shock Warning—Take precautions to avoid electrical shock.
  • Protective Conductor Terminal (PE)—Indicates a terminal that connects to accessible dead metal parts of the model. Connect the PE terminal(s) to an earth ground system (protective conductor) for safety.
  • Functional Earth Terminal (FE)—Indicates a terminal that connects to a measurement or control circuit. Connect FE terminals to an earth ground system for any functional purpose other than safety.

    • Protective Earth Ground

    Caution You must connect the RM-26999 to protective earth ground before powering on the system and taking measurements.
    • The facility installation shall provide a means for connection to protective earth; and
    • Qualified personnel shall install a protective earthing conductor from both protective earth terminals on the front panel of the RM-26999 to the protective conductor in the facility.
    Attention Vous devez connecter le RM-26999 à la terre avant de mettre le système sous tension et de prendre des mesures.
    • L'installation du site doit fournir un moyen de connexion à la terre ; et
    • Du personnel qualifié doit installer un conducteur de mise à la terre allant de la borne de mise à la terre située sur la face avant du RM-26999 jusqu'au câble de mise à la terre du site.

    Safety Guidelines for Hazardous Voltages

    A hazardous voltage is a voltage greater than 42.4 V peak voltage or 60 V DC in DRY LOCATIONS. If hazardous voltages are or will be connected to the device, take the following precautions.

    The hazardous voltage input status LEDs on the RM-26999 will turn on (YELLOW) when a voltage is applied to the input channel(s) above 50 V DC or 40 V AC, 60 Hz. If the LED is off, a voltage above 50 V DC or 40 V AC, 60 Hz, has not been applied to the input channel and/or the terminal block is not powered on.

    Caution Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local electrical standards.
    Attention S'assurer que le câblage à tension dangereuse est effectué par du personnel qualifié respectant les normes électriques locales.
    Caution Do not mix hazardous voltage circuits and human-accessible circuits on the same module.
    Attention Ne pas combiner des circuits de tension dangereuse et des circuits accessibles aux personnes sur le même module.
    Caution When module terminals are hazardous voltage LIVE, you must ensure that devices and circuits connected to the module are properly insulated from human contact.
    Attention Lorsqu'une haute tension dangereuse est appliquée aux bornes de l'appareil, s'assurer que les appareils et les circuits connectés au module sont correctement isolés de tout contact humain.
    Caution All wiring must be insulated for the highest voltage used.
    Attention Tout le câblage doit être isolé pour la plus haute tension utilisée.
    Warning Do not connect the RM-26999 to signals or use for measurements within Measurement Categories III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category III, or IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.
    Mise en garde Ne connectez pas le RM-26999 à des signaux dans les catégories de mesure III ou IV et ne l'utilisez pas pour des mesures dans ces catégories, ou des mesures sur secteur ou sur des circuits dérivés de surtensions de catégorie III ou IV pouvant présenter des surtensions transitoires supérieures à ce que le produit peut supporter. Le produit ne doit pas être raccordé à des circuits ayant une tension maximale supérieure à la tension de fonctionnement continu, par rapport à la terre ou à d'autres voies, sous risque d'endommager et de compromettre l'isolation. Le produit risque de tomber en panne et son isolation risque d'être endommagée si les tensions transitoires dépassent la surtension transitoire nominale. Une analyse des tensions de fonctionnement, des impédances de boucle, des surtensions temporaires et des surtensions transitoires dans le système doit être effectuée avant de procéder à des mesures.
