Introduction
General
Congratulations on your choice of UPS (Uninterruptible Power Supply). This UPS has been designed and produced for reliable and troublefree long-term use. 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 8 of this manual.
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. A background light is activated in case of an alarm or if one of the keys are pressed. No activity or no alarm for 5 minutes will automatically switch of the light. By pressing pressing and and simultaneously you increase the contrast, and by simultaneously you decrease the contrast.
Note: The display accuracy is ±1%, ±1 digit.
The alarm LED is together with an acoustic signal the indicator for unusual operating situations. The light changes from green to red in case of alarm. The keyboard is used for programming of operating parameters and for calling readouts of parameters / alarm messages.

Stop start
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 system off mode and from here back into normal operation via the "safe" push buttons.
2.2 Warning: Please read maintenance section, if UPS has to be stopped for more than one week.

Programming parameters
General
Some operating parameters can be programmed directly from the keyboard, but this has already been done during the commissioning. Unless you are quite sure of the consequence of changing the following parameters, then let it be a task for your local dealer, if needed. Parameters are programmed as shown in the example 4.2.3.

6.1
Alarms - What to do
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 arise.
6.2
The alarm stack
Description Access to the alarm stack
The alarm stack can be displayed by: Action 1. Press
2. Press
or
Scroll up or down through the alarm stack messages. Last message is "No (further) alarm". Exits the alarm stack. If not operated the system will exit the alarm stack automatically after 30 seconds.
3. Press
6.3
Alarm messages
The alarm messages are together with the events logger (described in section 7.0) part of a diagnostic system for the UPS service specialist. Before calling for assistance you may take one or more of the following actions. 1. "Battery defective" means no back-up capacity any longer. Call for assistance. "Battery Week" means reduced back-up capacity. Reset the "Battery week" alarm signal according to point 4.2 and start up a battery capacity test according to point 8.4. 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 16 hours, and with the same load as before start up 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. Check the local mains power supply. One or more fuses may be blown or somebody could by accident have switched off the supply. Check if the cooling air intake 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 bypass the UPS as described in the following section by means of the external service bypass switch if present.
NOTE: A battery monitor test can not be performed unless the battery is fully charged.

Preventive maintenance
General
The maintenance of the UPS systems should be carried out by trained service engineers. We recommend that you sign a service and maintenance contract.
8.2 8.3
Fan Battery
It is recommended to replace the fans every 3rd year.
Systems with built-in batteries have as standard a battery monitoring feature (option in other systems). Every time automatic cyclic or manual check is activated, the condition of the battery is checked. The result is one of following: 1. Battery is OK - nothing will happen 2. Battery has reduced capacity - "Battery week" is given 3. Battery capacity far to low - "Battery defective" is given The battery monitoring test is performed by taking out max. 25% of the energy in the battery. But if the battery monitor is not installed or the exact present back-up time has to be checked, a battery capacity test (8.4) is recommended at least every sixth month. For safety reasons battery tests should preferably be made during uncritical periods for the loads connected. Test the battery capacity / condition from the keyboard as follows:

Economy Operation
9.0
9.1
Economy operation
General
In economy operation 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 to 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 the same as already described in this guide with the exception of the following points: When starting up, the system will at first go into normal operation to ensure a fully charged battery, but will then switch into bypass after the programmed time (8-10 hours).
Note: When using economy mode there is NO power factor correction on the input, cabling dimensions should therefore be checked.
