The CompuMaster is an Uninterruptible Power Supply
(UPS) for essential loads like PC’s, IT systems and
similar device, consisting of
- a rectifier (battery charging)
- a battery as energy storage device during mains failure
(input supply for the inverter)
- an inverter to supply the connected loads when a
mains failure occurs
- a static stitch-over circuit to change AC-power supply
from mains to inverter as long as mains is not available
and
- a filter circuit, situated on the mains input

Bloc diagram of a UPS
The UPS has to be connected between mains distribution
and the load via standard mains socket.
Under normal operating conditions, i.e. the Compu-
Master is supplied by mains, the battery will be fully
charged by the rectifier. Loads connected to the Compu-
Master will be supplied with filtered mains voltage.
36

pm-.-
--
When mains is not available or in case of decreased mains
voltage to 85% of nominal value or less the inverter will take
over the supply of the connected loads.
The CompuMaster w-ill supply the load for a time according to the
battery capacity. This autarky time depends in general on the
load power. In case of restored mains supply the UPS will switch
over the load from inverter to mains operation, i.e. the load will
be supplied by mains again and the battery will be recharged.
In case of a mains blackout the mains input will be automatically
disconnected by a two-pole-switch to fulfil1 safety requirements of
german standards (VDE) and to avoid backfeeding from the inver-
ter to the mains.
The availability of the following three protecting functions is
guaranteed:
+ Protection against mains blackout
Due to the type of CompuMaster the UPS will provide automati-
cally output power up to 3OOVA, 600VA oder IZOOVA for a time
being sufficient to shut down and switch off the system accor-
dingly via shut-down software. The effective autarky time differs
individually and depends in general on the power consumption of
your connected system load.
+ Protection against mains disturbance
In case of an input voltage change to less than 85% or more than
110% of nominal value, the CompuMaster initialises the change-
over to battery operation automatically and supplies the load with
AC-voltage to minimize the risk of data loss or damage.
+ Protection against electromagnetical disturbance
Disturbanc.es and problems caused by HF will be reduced by the
use of an EMI filter network

subject to the CompuMaster as well as the battery
concerning erection, operation and maintenance to be
complied with.
The UPS is connected to hazardous voltage. Opening of
the unit is only allowed to qualified and authorized
personnel. Repairs are only allowed to qualified service
personnel !
Hazardous voltage may be applied to the output termi-
nals as well as mains is not connected, because the UPS
will be still running on it’s internal power supply
(battery) !

Is
Duly earthing of the unit is a must regarding the pro-
tection of the personnel !
It is only allowed to connect to and operate the Compu-
Master at AC-voltage 230V of a mains distribution with
protective earth by using a VDE-tested or equivalent
mains connection cable with protective earth contact
(enclosed).
Attention regarding burn (personnel) and fire !
The ability of potential high short-circuit currents may
lead to melting connectors and firing with the result of
severe skin burns !
The unit is provided with an acoustic signalling device to
warn in case of low battery voltage as well as if the UPS
does work in an abnormal state (see chapter 4.6, danger
signals).

teries:
Lay aside wrist-watches, rings and other metal objects !
Use insulated tools only !
41

For daily use of PC’s or other device the mains switch
should remain in the on-position. It should be avoided
to switch on or off the Computer by using the mains
switch.
For longer periods without necessity of using the UPS
the mains switch should be set to the off-position. In the
case that the mains distribution will be disconnected
each evening, the CompuMaster should be switched off
too to avoid discharging of the battery, because the in-
verter will start automatically after mains break down.
To protect the battery aginst damage you never should
close the mains switch with disconnected UPS from the
mains !
The battery will not be charged when the UPS has been
switched off. Please note chapter 5.1.

4.4 Initial start-up
Marking of the mains switch (item 3 of pict. on page 46):
,,I“ for ,ON” and ,,O” for ,,OFF“
1) Make sure, that the mains switch of UPS is in the
OFF-position (item 3 of picture on page 46)
2) Connect the input of UPS (item 12 of pict. on page 46)
with the connection cable (female contact) enclosed
and plug the connector to a suitable wall plug with
earthing contact.
3) Connect the output of the UPS (item 11 of picture on
page 46) to the load. Please use the enclosed second
connection cable only. The load (e.g. PC) should still
be switched off.
4) Set the mains switch of UPS to the ON-position.
5) The UPS will start with a self test changing automati-
cally to normal operation afterwards. In the case that
the UPS will be remaining in testing mode, please fol-
low the instructions in chapter 4.6 ,,Danger signals“
(page 49ff)-
0
If you can’t find any solution concerning the problem
occured, please switch off the equipment completely and
contact your dealer.
6) When the UPS is running in normal operation, please
switch on your load (e.g. PC).
Afterwards the UPS should remain in the ON-position for
battery charging for two days. Thus the battery capacity
will be increased to a normal state.
47

4.5 Operation
At first the UPS must be connected to a suitable mains
wall plug. Then set the mains switch to the ON-position.
Following to that procedure output voltage will be
available. The green LED ,,NORMAL” will be illuminated
or blinking when mains voltage is within nominal range;
if not, another LED will be illuminated in connection
with a sounding danger signal.
In normal operation, i.e. mains voltage is available, the
integrated battery charger will float the battery and the
inverter will be set to the stand-by mode by the
monitoring. In case of mains blackout as well as with de-
creasing mains voltage to 85% or increasing mains volta-
ge to 110% the inverter w-ill be set to the stand-alone mo-
de supplying the load with AC voltage.
In case of battery undervoltage a danger signal of the
UPS will sound for approx. 1 to 3 minutes. Afterwards
the battery will be disconnected by the UPS.
In this case please switch off the UPS by the mains
switch asap !
After mains has been restored, the UPS must be switched
on manually by the mains switch for battery charging to
overcome the next mains failure.
