GEHydran* M2 Transformer Gas Monitoring System Installation Guide

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, and could lead to property damage, 

personal injury and/or death. 

• Installation and maintenance of the Hydran M2 must be carried out by qualified 

personnel only. Please advise station operator prior to maintenance. Working 

inside the Hydran M2 may trigger unwanted alarms due to parameter changes, 

power shutdown, system rebooting or electrostatic discharge. 

• For a maximum distance of 15 m (50 ft) from the power source, use a 2.08 mm2 

(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, et pourrait entraîner des dommages 

à la propriété, des blessures corporelles et/ou la mort. 

• L'installation et l'entretien du Hydran M2 doivent être effectués par du personnel 

qualifié seulement. Veuillez aviser l'opérateur du poste avant l'entretien. Travailler 

à l'intérieur du Hydran M2 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 (14-AWG) et une protection contre les surintensités. 

[ES] (in Spanish) ADVERTENCIA:

• Se debe c

 Cualquier desviación al respecto puede causar daños irreparables al 

transformador que está bajo monitoreo y/o al Hydran M2, asimismo puede ser 

causa de daños materiales, lesiones corporales y/o muerte. 

• La instalación y mantenimiento del equipo Hydran M2 se reserva únicamente al 

personal perfectamente cualificado. Aconseje por favor a operador de la estación 

antes del mantenimiento. El trabajo dentro del Hydran M2 puede accionar alarmas 

indeseadas debido a los cambios del parámetro, parada de la energía, sistema 

que reanuda o descarga electrostática. 

• Para una distancia máxima de 15 m (50 pies) de la fuente de alimentación, utilice 

un cable de 2,08 mm2 (14-AWG) y una protección contra las sobrecargas de 

corriente. 

[DE] (in German) WARNUNG:

• Alle Abläufe in diesem Handbuch müssen strengstens befolgt werden. 

• Jede Abweichung davon könnte dem zu überwachenden Transformator und/oder 

dem Hydran M2 unwiderrufliche Schäden zufügen, und könnte zu Sachschaden, 

Personenverletzung und/oder Tod führen. 

• Installation und Wartung des Hydran M2 dürfen daher nur von qualifiziertem 

Personal durchgeführt werden. Verständigen Sie bitte den Bediener der 

Schaltanlage vor der Wartung. Das Arbeiten innerhalb des Hydran M2 kann 

aufgrund von Parameteränderungen, Spannungsabschaltung, Neubooten des 

Systems oder elektrostatischer Entladung unerwartete Alarme auslösen. 

• Für eine maximale Entfernung von 15 m von der Spannungsquelle, verwenden 

Sie ein 2,08 mm2 Kabel (14 AWG) und ein Überstromschutz.

[IT] (in Italian) ATTENZIONE:

• Tutte le procedure del presente manuale dovranno essere eseguite in totale 

conformità.

• Qualsiasi deviazione dallo stesso manuale potrebbe causare danni irreversibili al 

trasformatore sotto monitoraggio e/o all’ Hydran M2, e potrebbe causare danni 

alla proprietà, lesioni personali e/o alla morte.

• L’installazione e la manutenzione del Hydran M2 devono essere eseguite solo ed 

esclusivamente da personale qualificato. Avissare l’operatore della stazione prima 

di manutenzione. Funzionando all’interno del Hydran M2 può fare scattare degli 

alarmi indesiderabili e cambiamenti dei parametri, arresto dell’alimentazione, un 

“reboot” del sistema o scarico elettrostatico. 

• A una distanza massima di 15 m dalla fonte di energia usare un cavo 2.08 mm2

(14-AWG) e una protezione di sovracorrente.

[SV] (in Swedish) VARNING:

• Alla procedurer i manualen måste följas noggrant. 

• Varje avvikelse från dessa procedurer kan orsaka oåterkalleliga skador på den 

övervakade transformatorn och/eller på Hydran M2 samt leda till 

egendomsförlust, personskada och/eller livsfara. 

• Installation och underhåll av Hydran M2 måste utföras av behörig personal. Råd 

var god posterar operatören före underhåll. Funktionsduglig insida Hydran M2 kan 

starta oönskade parameterändringar för larm tack vare, driver avstängning, 

systemomstart eller elektrostatisk urladdning. 

• För ett maximalt avstånd på 15 m från kraftuttaget, använd 2,08 mm2 kabel (14-

AWG) och ett överströmsskydd.

For a typical transformer, the four most common locations to install the Hydran 

M2 are shown in Figure 10. For details, refer to Table 1 overleaf.

If these typical locations cannot be used, contact the GE 

Energy Customer Service for help to determine an 

acceptable alternative location.

• ELECTRICAL SHOCK HAZARD! Turn off the electric power at 

the fuse box or service panel before making any electrical 

connections, and ensure a proper ground connection is 

made before connecting line voltage. Failure to do so can 

result in property damage, personal injury and/or death.
