Safety Warnings In Six Languages
[EN] (in English) WARNINGS:
•All procedures in this manual must be strictly adhered to.
•Any deviation from these could cause irreversible damage to the transformer
being monitored and/or the Hydran M2-X, and could lead to property damage,
personal injury and/or death.
•Installation and maintenance of the Hydran M2-X must be carried out by qualified
personnel only. Please advise station operator prior to maintenance. Working
inside the Hydran M2-X may trigger unwanted alarms due to parameter changes,
power shutdown, and system rebooting or electrostatic discharge.
•For a maximum distance of 15 m (50 ft) from the power source, use a 2.08 mM2-X
(14-AWG) cable and an overcurrent protection.
[FR] (in French) ATTENTION:
•Toutes les procédures dans ce manuel doivent être observées rigoureusement.
•Tout écart par rapport à celles-ci pourrait causer des dommages irréversibles au
transformateur surveillé et/ou au Hydran M2-X, et pourrait entraîner des
dommages à la propriété, des blessures corporelles et/ou la mort.
•L'installation et l'entretien du Hydran M2-X doivent être effectués par du personnel
qualifié seulement. Veuillez aviser l'opérateur du poste avant l'entretien. Travailler
à l'intérieur du Hydran M2-X peut déclencher des alarmes non voulues en raison
de changements à des paramètres, d'arrêt de l'alimentation, de remise en marche
du système ou de décharge électrostatique.
•Pour une distance maximale de 15 m (50 pi) de la source d'alimentation, utiliser un
câble de 2,08 mM2-X (14-AWG) et une protection contre les surintensités.
[ES] (in Spanish) ADVERTENCIA:
•Se debe cumplir estrictamente con todos los procedimientos señalados en este
manual.
•Cualquier desviación al respecto puede causar daños irreparables al
transformador que está bajo monitoreo y/o al Hydran M2-X, asimismo puede ser
causa de daños materiales, lesiones corporales y/o muerte.
•La instalación y mantenimiento del equipo Hydran M2-X se reserva únicamente al
personal perfectamente cualificado. Aconseje por favor a operador de la estación
antes del mantenimiento. El trabajo dentro del Hydran M2-X puede accionar
