Introduction
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.
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 mes-
sages. 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 and simultaneously you increase the contrast, and by
pressing and simultaneously you decrease the contrast.
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 read-
outs of parameters / alarm messages.
Note:
The display accuracy is
±1%, ±1 digit.

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 system off mode
and from here back into normal operation via the “safe” push buttons.

4.0 Programming parameters
4.1 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.

6.0 Alarms - What to do
6.1 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 arise.
6.2 The alarm stack
The alarm stack can be displayed by:
Action Description
1. Press Access to the alarm stack
2. Press or Scroll up or down through the alarm stack messages.
Last message is “No (further) alarm”.
3. Press Exits the alarm stack. If not operated the system
will exit the alarm stack automatically
after 30 seconds.
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.
2. Check the local mains power supply. One or more fuses may be blown or some-
body could by accident have switched off the supply.
3. Check if the cooling air intake on your UPS has been blocked.
4. Check if somebody has switched more load on the UPS - the max. output capac-
ity may be exceeded.
5. 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.

6.4 The events logger
The events logger is a memory stack, in which the last 250 events are stored in the
same succession as they arose. (Showing the latest at first).

7.2.3 Isolating one UPS for service/maintenance
In a redundant system one UPS can be isolated for service/maintenance without
affecting the other parallel UPS(s).
1. Check that the remaining UPS(s) will be able to carry the load when one UPS is
isolated.
2. Switch off the system to be isolated for maintenance by pushing both the green
“ON” and the red “OFF” key simultaneously.
3. Disconnect battery, mains, and output by opening battery MCCB/fuse and
turning input switch (Q001) and output switch (Q002) to position “0”.
When Q002 is in position “0” the UPS can be operated and tested as a single
system without affecting the other parallel UPS(s).
Switching back the UPS to normal parallel/redundant operation
1. Turn the input switch (Q001) and the output switch (Q002) to position “1”.
2. Charge capacitors, connect battery and start up the UPS as described in chapter
5.0.
The UPS will automatically switch to normal operation and start load sharing
with the other parallelled UPS(s).
Warning!
The system will discharge built-
in capacitors. However, before
working on the system check
with a multimeter that there is
no dangerous voltage on the
terminals .

8.0 Preventive maintenance
8.1 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 Fan
It is recommended to replace the fans every 3rd year.
8.3 Battery
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:
Preventive maintenance

20 User Guide DP300E
7OA0001 GB rev.09
Warning:
The UPS must at least be in
operation for min. 16 hours
in a 3 month period to
ensure that the battery is
sufficiently charged. If not
the battery might be dam-
aged.
