1.0 INTRODUCTION
1.1 General Congratulations on your choice of UPS (Uninterruptible Power Supply). This UPS has been designed and produced for reliable and troublefree long-term use as the major parameters. For you it means that once installed and commissioned, you can forget it. You only have to arrange a preventive maintenance as described in section 7 of this manual. For the user, who wants to get more familiar with the UPS - not needed for the daily use - the following information is useful.
1.2
The display unit The display unit - placed on the front of the UPS - is the link between user and UPS. It consists of a display, an alarm LED, and a keyboard. The display is used for showing parameters, measured values, and alarm messages. The alarm LED is together with an acoustic signal the indicator for unusual operating situations. The keyboard is used for programming of operating parameters and for calling read outs of parameters / alarm messages.
2.0 STOP - START
2.1 General This guide contains the information necessary for the operation of the system after installation and commissioning.
2.2
Stop Open the right front door and activate the red "OFF" push button. Alarm LED lights. Acoustic alarm sounds for 30 seconds.

3.0 PROGRAMMING PARAMETERS
3.1 General Some operating parameters can be programmed directly from the keyboard, but this has already been done during the commissioning. Unless you are not quite sure of the consequence of changing the following parameters, then let it be a task for your local dealer, if needed. Parameters Std. factory setting English OFF OFF Comments Language of text in display Automatic restart by mains return if the battery has been discharged due to a long mains failure ON will switch the system into by-pass mode NOTE: The system must not run in bypass mode for longer periods of time as the batteries will not be recharged ON results in boost charge Aut. boost charge after battery operation Check of back-up time (See section 7.3) Check of battery condition by 25% discharging Press key after selecting this parameter to reset the battery monitor alarms and flush corresponding messages in the alarm section. OFF used in case of very unstable mains frequency

5.0 ALARMS - WHAT TO DO
5.1 General Alarms are indicated by the red lamp (above the upper left corner of the keyboard) and by a 30 secs. acoustic signal. An alarm is registered in an alarm stack as long as it is present, and if more in the same succession as they arose. The alarm stack can be displayed by: 1. Press 2. Press 3. Press
7LA0002GB rev 05
5.2
to access the alarm stack. or to move inside the alarm stack. (Last message is "No further alarms").
to leave or wait 20 seconds.

5.3
The alarm messages are together with the events logger (described in section 6) parts of a diagnostic system for the UPS service specialist. Most of the messages are therefore probably "black talk" to you. But before calling for assistance you can take one or more of the following actions: 1. 2. 3. 3. 4. If the massages "Battery monitor warning"* of "Battery monitor alarm"* pop up go to point 5.3.6. Check the local mains power supply. One or more fuses may be blown or somebody could by an accident have switched off the supply. Check if the cooling air intake bottom front or exhaust on the top cover on your UPS has been blocked. Check if somebody has switched more load on the UPS - the max. output capacity may be exceeded. If there is no output voltage from the UPS - the mains supply is present and atempt to restart gives no result - by-pass the UPS by means of the external service by-pass switch if present else open the front door and turn the by-pass handle form "OFF" og "On". Then call for assistance. If there is no output voltage from the UPS - the mains supply is present and atempt to restart gives no result - by-pass the UPS by means of the external service by-pass switch if present else open the front door and turn the by-pass handle from "Off" to "ON". Then call for assistance. "Battery monitor alarm"* means no back-up capacity any longer. Call for assistance. "Battery monitor warning"* means reduced back-up capacity. Reset the "Battery monitor warning" alarm signal according to point 3.2 and start-up a battery capacity test according to point 7.3. When finished - record the obtained back-up time and reset an eventual new alarm from the battery monitor. Let the UPS recharge the battery for at least 8 hours, and with the same load as before start-up again a second battery capacity test. If this results in improved back-up time continue with further capacity tests until none or insignificant improvements take place. Above might "wake-up" the battery - else call for assistance

6.0 THE EVENTS LOGGER
6.1 General The events logger is a memory stack, in which the last 100 events are stored in the same succession as they arose. (Showing the latest at first). Events stored are the alarms and the following operational modes: MODE MPU is reset Stand-by Normal operation Battery operation By-pass operation COMMENTS UPS has been totally switched off UPS has been in stand-by mode UPS has been in normal operation UPS has been in battery operation UPS has been in by-pass operation
6.2
The events stack can be displayed by:
1. Press 2. Press 3. Press
and or
simultaneously to get access to the events stack. to move inside the events stack. (Last message is "No events").
to display the time where the event happend (Time is UTC = Universal Time Coordination = GMT) to leave the events stack, or wait 20 seconds for automatic reset.

7.0 PREVENTIVE MAINTENANCE
7.1 General The maintenance of the UPS systems should be carried out by trained service engineers. We recommend that you enter into a service and maintenance contract. *Only for systems with Battery Monitor.

Fan It is recommended to replace the fans every 3rd year. Battery Every half year it is recommended to check, whether the battery has still a capacity to ensure sufficient back-up time by performing a battery capacity test. Test the battery capacity from the keyboard as follows: 1. Press

instead of
Please notice that after a battery capacity test it last about 8 hours before the battery is recharged and full back-up time again is available. Battery tests should preferably be made during uncritical periods of computer operation for reasons of safety! If the UPS has to be taken out of operation for some time it is recommended to disconnect the battery in order to prevent it from being totally discharged. The information how to do this can be found in the installation guide. But the UPS must at least be in operation for min. 12 hours in a 3 month period to ensure that the battery is sufficient charged. Otherwise the battery also might be damaged.
8.0 ECONOMY MODE
The load is in economy mode supplied directly from the mains, however the UPS is monitoring the mains and the output voltages and will in case of mains failure switch into battery operation without interruptions. The system will in order to keep the battery fully charged at all times switch into normal operation in a pre-programmed sequence. When starting up, the system will first go into normal operation to ensure a fully charged battery but will then switch into by-pass after the pre-programmed time (typically 8 - 10 hours).
*Only for systems with Battery Monitor.
