2.0 BATTERY INSTALLATION
2.1 Safety
Special care should be taken when working with the batteries associated with the Liebert EXM
Battery System equipment. When all the cells are connected together, the battery terminal
voltage will exceed 288VDC and is potentially lethal. A primary safety consideration is to install
the battery equipment in an isolated area, accessible only to properly trained and qualified
maintenance personnel.
Lead-acid batteries can present a risk of fire because they generate hydrogen gas. In addition, the
electrical connections must be protected against accidental short circuits which can cause
sparks. The following procedures should be followed:
• DO NOT SMOKE when near batteries.
• DO NOT cause flame or spark in battery area.
• Discharge static electricity from body before touching batteries by first touching a grounded metal
surface.
• After replacing battery jars in a battery cabinet, replace the retaining straps that hold the jars in place on
the shelves. This will limit accidental movement of the jars and connectors should the cabinet ever need
to be repositioned or relocated.
Regular maintenance of the battery module is an absolute necessity. Periodic inspections of
battery and terminal voltages, specific gravity and connection resistance should be made. Strictly
follow the procedures outlined in the battery manufacturer’s manual, available on the
manufacturer’s Web site.
Valve-regulated lead-acid (sealed-cell) batteries do require periodic maintenance. Although
maintenance of electrolyte levels is not required, visual inspections and checks of battery voltage
and connection resistance should be made.
NOTICE
Risk of equipment damage. Batteries should be cleaned with a dry cloth or a cloth lightly moistened with
water. Do not use cleaners on the batteries. Solvents can make the battery cases brittle.
WARNING
Risk of electrical shock and fire. Can cause equipment damage, personal injury or death.
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batteries.
AVERTISSEMENT
Risque de décharge électrique et d’incendie. Pouvant entraîner des dommages matériels,
des blessures et même la mort.
Le remplacement des batteries doit être effectué ou supervisé par des membres du
personnel dotés des compétences requises et connaissant les précautions à prendre. Le
personnel non autorisé ne doit pas avoir accès aux batteries.
