Introduction 1.0 Introduction This UPS system is designed to offer reliable and problem-free power supply for several years. The system requires only a minimum of maintenance, but we recommend you follow the maintenance guidelines described in the “Maintenance & Testing” section of this User Guide. 1.1 Display Unit The display unit (located on the front of the UPS) is the link between the user and the UPS and consists of a display, an alarm LED indicator and a keyboard.
UPS Stop/Start 2.0 UPS Stop/Start WARNING! AC voltage generated either from batteries or utility may be present at UPS output. Always disconnect AC input supply source, switch off UPS, AND switch off DC. TEST BEFORE YOU TOUCH! Some UPS systems have a factory-set auto-start feature, which automatically switches on the UPS whenever utility supply is switched on (AC line). See the “Parameter Settings” section in this User Guide for instructions on how to de-activate this function.
Operation 3.0 Operation The keyboard is used to program and control parameters and to display alarm messages and measured values.
Operation 3.1 Operation Modes The display automatically indicates which mode the unit is operating in. See Table 1 below for sample display messages and an explanation of each. Table 1: Operating Modes Sample Display Mode Operation Mode Description Normal Operation load power ##% The UPS is in the normal operation mode. During normal operation, utility (AC line) passes through the UPS and to the load. The inverter regulates the output and charges the batteries.

Alarms and Events 5.0 Alarms and Events Alarms are indicated by a red light (above the left-hand corner of the display) and a 30-second acoustic signal. An alarm is registered in the alarm log as long as it is present. All alarms are also registered in an event logger and remain there in a stack with room for 250 events. The events are stored in order of occurance, with the latest event appearing first. 5.
Alarms and Events 5.3 Alarm Messages Table 5: Possible Alarms Alarm Message Description Action Battery MCB is off The battery breaker is open. If bypass voltage is within tolerance, the unit transfers to static bypass operation. If not, the unit transfers to stand-by and does not supply output voltage. At the battery breaker, set the precharge/discharge switch to the precharge position and hold it in this position until the LED turns off.
Alarms and Events Table 5: Possible Alarms Charge reg. error (reg. = regulator) Failure in charge regulation. The unit transfers to battery until the “Low DC shutdown” alarm occurs; then, it transfers to stand-by and does not supply output voltage. Call APC Global Service. External service switch activated The external service bypass switch is in the line position. The unit is in stand-by and does not supply output voltage. However, the loads may be receiving power from the external manual bypass.
Alarms and Events Table 5: Possible Alarms High output voltage (This alarm is usually only listed in the events log) The output voltage is higher than the alarm setting. The unit stays in the normal operation mode. If the alarm is not cleared, the unit will transfer to static bypass operation if bypass is within tolerance. If bypass is not within tolerance, the unit will transfer to stand-by and will not supply output voltage.
Alarms and Events Table 5: Possible Alarms Low DC shutdown (This alarm is normal when the UPS has run on battery for a long time) The UPS has been running on battery power because of a power outage or problems in the AC input. Battery voltage has dropped below the shutdown setting, and the UPS has shut down. If bypass is within tolerance, the unit will transfer to static bypass operation. If not, the unit will transfer to stand-by and will not supply output voltage.
Alarms and Events Table 5: Possible Alarms Mains is out of tolerance (This alarm occurs during a power outage) The utility (AC input) voltage is too high or too low, so the unit transfers to battery operation. If AC input returns to normal, the unit transfers back to normal operation. If not, the unit continues to run on battery until the “Low DC shutdown” alarm occurs. Then, if bypass voltage is within the range programmed into the UPS, the unit transfers to bypass.
Alarms and Events Table 5: Possible Alarms Output is out of tolerance The output voltage is too high or too low (out of tolerance). If the alarm was caused by high output voltage, the unit transfers to static bypass operation if bypass is within tolerance. If bypass is not within tolerance, the unit transfers to stand-by and does not supply output voltage. If the alarm was caused by low output voltage, the unit transfers to static bypass operation if bypass is within tolerance.
Alarms and Events Table 5: Possible Alarms Static switch 1 temp. warning The temperature on the heat-sink for the main static switch is higher than the warning setting. The unit’s status does not change. However, if the temperature continues to rise, the unit will sound a “Static switch 1 temp. shutdown” alarm. Find the vents for the UPS fans and check to see if the fans are operating. Do not try to open the unit, and do not insert anything into a fan vent.
Alarms and Events Table 5: Possible Alarms TSM 1 temp. shutdown Inverter module 1 has shut down because the temperature on the heat-sink is higher than the shutdown level. If bypass is within tolerance, the unit transfers to static bypass operation. If not, the unit transfers to stand-by mode and does not supply output voltage. Find the vents for the UPS fans and check to see if the fans are operating. Do not try to open the unit, and do not insert anything into a fan vent.
Alarms and Events Table 5: Possible Alarms TSM 3 temp. shutdown Inverter module 3 has shut down because the temperature on the heat-sink is higher than the shutdown level. If bypass is within tolerance, the unit transfers to static bypass operation. If not, the unit transfers to standby and does not supply output voltage. Find the vents for the UPS fans and check to see if the fans are operating. Do not try to open the unit, and do not insert anything into a fan vent.
Alarms and Events 5.4 Displaying the Events Log The events log is a list of the last 250 alarms and operational modes. This log includes the time and date of each event. Most entries in this log will be alarms (see the “Alarms and Events” section in this User Guide for a description of alarms). Other entries describe operating modes (see the “Operation Modes” section in this User Guide for details); the table below lists and describes these Event Log messages. 1.
