CAUTION

When battery shutdown occurs, no power will be supplied to the critical load unless power is available through the bypass line from the utility source (or from an engine generator set). If you anticipate a battery shutdown (and an engine generator set is not available), either transfer the load to bypass (if available) or perform a controlled shutdown of the critical load.

If the Battery Time screen is displayed while the battery is not discharging, it will display the present Battery Charge percentage and the results of the previous discharge event.

NOTE

1. During initial UPS start-up, the Battery Charge will display 100%, even though actual state of charge may be slightly less. It will normally take three to four days of operation to completely charge the battery. After the battery is fully charged the first time, Battery Charge will be an accurate indication of battery status.

2.If Calculated Time Remaining is less than Rated Time Remaining, a battery problem may be indicated. Battery maintenance personnel should thoroughly examine the battery plant for factors that may reduce battery performance, such as:

•Age of battery

•Excessive battery discharge/recharge cycles

•Bad or weak cells

•Low acid levels in flooded cells

•Loose electrical connections

•Ambient temperature extremes

•Dirty battery jar covers.

3.If the battery plant has been thoroughly examined for proper maintenance and condition, and the Calculated value is still less than 80% of Rated value, contact Liebert Global Services.

The Series 600T records information about each discharge event. This data can be reviewed on the Battery Cycle Monitor screen, as described in 3.1.4 - Status Reports Screens.
