Special care must be taken when working with the batteries associated with this equipment.
When they are connected together, the battery terminal voltage will exceed 400VDC and is
potentially lethal.
AVERTISSEMENT

Risque de décharge électrique pouvant causer des blessures graves, voire mortelles.
Des précautions particulières doivent être prises lors de travaux touchant les batteries
associées à cet équipement.
Lorsque les batteries sont branchées ensemble, la tension à la borne d'une batterie dépasse

• Verify that the correct equipment is being installed. The equipment supplied has an identification
tag on the interior doors reporting the type, size and main calibration parameters of the UPS.
• Verify that the UPS room satisfies the environmental conditions stipulated in the equipment
specification, paying particular attention to the ambient temperature and air exchange system.
