4.4.2Torque Requirements

All electrical connections must be tight. Table 15 provides the torque values for the connections in the UPS. Use these values unless the equipment is labeled otherwise.

NOTE

Refer to the battery manufacturer’s manual, available on the manufacturer’s Web site, for the proper torque values required for the battery.

4.5Detection of Trouble

It is important that the operator check the instrument readings if abnormal equipment performance is suspected. Any metered value that differs appreciably from normal could mean an impending mal- function and should be investigated.

Items to check include:

•Output voltage of all phases should be within 2% of normal voltage. Output currents on each phase should not normally differ by more than 20%. If a greater difference is noted, the load is unbalanced and corrective action should be taken to redistribute the load, if possible.

•If the UPS has not operated on battery power during the last 10 hours, the batteries should require little charging current. Battery mimic should indicate normal DC voltage with the battery charge current no more than 31 Amperes.

•Input current on each phase should be within 10% of the average input current.

•Alarm messages indicate malfunction or impending malfunction. A daily check of the Operator Control Panel will help to provide an early detection of problems. Refer to Table 9 and Table 10 to interpret alarm messages.

•Tracing a problem to a particular section is facilitated by alarm messages and the metered parameter indications. These are stored in the Status Reports and can be displayed at the Opera- tor Control Panel or at an optional terminal. A Liebert Global Services engineer will be familiar with test points inside the unit.

NOTE

If the UPS system has a blown fuse, determine the cause should be determined before replacing the fuse. Contact Liebert Global Services for assistance.
