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 According to electrical regulations only the local authorized electrical installer is normally allowed to perform a complete switching in and out of the UPS, as it involves operation of the battery supply breaker, where touch of high voltage parts is possible. For above reasons the normal user can only switch the UPS into stand-by mode and from here back into normal operation. Stop Open the front door and activate the red "OFF" push-button Alarm LED lights. Acoustic alarm sounds for 10 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 8 hours continous boost charge Aut. boost charge for 8 hours after battery operation Special use Check of back-up time by 100% discharging* Check of battery condition by 25% discharging* Pressing key after selecting this parameter reset the battery monitor alarms and flush corresponding messages in the alarm section.

If not pressed, automatic switch back will be performed after 20 seconds. Year, month, day Hour, minute, second UTC = Universal Time Coordination (Same as GMT)
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, registering the latest at first. The alarm stack can be displayed by: 1. Press 2. Press to access the alarm stack. or to move inside the alarm stack. (Last message is "No alarms").
5.2
3. Press

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. 4. 5. If the messages "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 down on the front door 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 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 250 events are stored in the same succession as they arose, storing the latest at first. Events stored are the alarms and the following operational modes: MODE MPU is reset Stand-by Normal operation By-pass operation 6.2 COMMENTS UPS has been totally switched off UPS has been in stand-by mode UPS has been in normal operation UPS has been switched into by-pass operation
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. Fan The fan is recommended to be replaced every 3rd year. Battery Every three months it is recommended to check, whether the battery has still a capacity / condition to ensure sufficient back-up time by performing a battery capacity /condition test.

where "xxx" is the actual back-up time in minutes. 6. Press or wait 20 secs. until display shows Normal operation load power xx%
To interrupt a running test - perform point 1-3 but press key
instead of
in point 3.
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 has to be switched off from the mains supply to prevent a total discharge and damage of the battery. 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
In economy mode the load is 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 batteries fully charged at all times switch to normal operation in a pre-programmed sequence. The operation of the system is described in this guide with the exceptations of the following points: 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).
