Maintenance

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 mainte- nance of electrolyte levels is not required, visual inspections and checks of battery voltage and connec- tion resistance should be made.

NOTE

Do not use cleaners on the batteries. Solvents can make the battery cases brittle. Use only a dry cloth or a cloth moistened in water.

Since individual battery characteristics are not identical and may change over time, the UPS module is equipped with circuitry to equalize battery cell voltages. This circuit increases charging voltage to maintain flooded type battery cells at full capacity.

NOTE

Do not use equalize charging with valve-regulated lead-acid batteries. Consult the battery manufacturer’s manual, available on the manufacturer’s Web site, for specific information about equalize charging.

The equalizing charge time period is adjustable from zero to 72 hours and can be initiated automati- cally or manually. Refer to 3.0 - Operation.

Matching Battery Cabinets (Optional)

Although the individual battery cells are sealed (valve-regulated) and require only minimal mainte- nance, the Battery Cabinets should be given a periodic inspection and electrical check. Checks should be performed at least annually to ensure years of trouble-free service.

Voltage Records: With the Battery Cabinet DC circuit breaker closed and the connected UPS oper- ating, measure and record battery float voltage. With the DC circuit breaker open, measure and record the nominal (open circuit) voltage. Both these measurements should be made across the final positive and negative terminal lugs. Compare these values with those shown below. The recorded nominal voltage should be no less than the value shown, while the recorded float voltage should be within the range shown. If a discrepancy is found, contact Liebert Global Services.

Power Connections: Check for corrosion and connection integrity. Visually inspect wiring for discol- ored or cracked insulation. Clean and/or retighten as required. Refer to torque specifications in Table 15.

Battery Cell Terminals: Check for discoloration, corrosion and connection integrity. Clean and tighten if necessary. Note that when installing a new battery, the initial torque value is 5 lb.-in. more than the retorque value. Table 13 shows battery retorque values.
