1.2 Short description
The accumulator buffered DC supply works according to the standby parallel principle and guarantees, in con-
nection with a lead accumulator and for a certain time interval, a safe upkeep of the DC supply in case of a
mains failure. The overall output current is split up between consumer supply and lead accumulator charge.
The power supply is characterized by the following properties:
Switching power supply with I/U charging characteristic
aktiv power factor correction (PFC)
Micro-controller supported lead accumulator management
RS232 for monitoring and parameterization
Temperature adjustment of the charging voltage by an external sensor
2 Transportation and storage
The transportation of the unit may only be carried out in the original packaging. During transportation and stor-
age the environmental conditions must be observed (see section 11 Technical Data). The units must be pro-
tected against humidity and direct sunlight. If lead accumulators are included, they must be recharged at least
each half year in case of longer storage.
3 Installation and connection
3.1 Installation
The unit must be installed in a way that the necessary cooling is guaranteed. A minimum distance of ≥ 75mm
must be kept to neighbouring units or assemblies in the area of the ventilation slots.
The installation must always be performed in a way that sufficient air circulation through the unit is ensured. All
fixing points must always be used for fixing the unit.
The specific environmental temperature must not be exceeded. The maximum mounting height without load
reduction amounts to 2000 m above sea level.
The power supply features protective system IP20, but the VdS guidelines recommend protective system
IP30. To fulfill this requirement, the power supply must be installed additionally in a housing or wall housing
with the corresponding protective system.

NOTE
If swarf could fall onto or into the unit, it must be
covered during installation. (Danger of short-
circuit!)

3.2 Connection
Prior to connection, the DC voltage supply values must be checked for compliance with the values given on
the label. Connect according to the designations of the connection terminals (see terminal assignment, sec-
tion 3.7 Circuit diagram). Not used connection screws must be tightened.

NOTE
The external energy supply must be connected to a power circuit with its own, individually identi-
fied fuse (16A).
From that fusing, there must be only one more fusing up to the low voltage side supply point on
the electric mains (service entrance box).
The interruption of the power circuit to the external energy supply caused by switching off other
equipment must be excluded.

NOTE
In case of overload, the DC output current is composed of the maximum charge rectifier cur-rent
and the lead accumulator current. The DC output circuit must be fused externally in order to
avoid overload!
If the external power supply is installed as a part of a fire alarm system, the following regulations must be ob-
served in their currently valid version:
DIN 14675 “Fire detection and alarm systems - design and operation”
DIN VDE-0833, part 1 + 2 “Alarm systems for fire, intrusion and hold up“
DIN VDE-0800 “Construction and operation of telecommunication facilities including
information processing facilities”
DIN VDE-0165 “Construction of electrical systems in areas with risk of
explosion”
Guideline VdS-2095 “VdS Guidelines for automatic fire detection and alarm systems,
Planning and Installation”
VDE 0100 “Installation of power circuits
with nominal voltages up to 1000 V”
EN 60204 “Safety of machinery - Electrical equipment of
machines“
DANGER

The lead accumulators are connected to the accumulator cables of the external power supply. The lead accu-
mulators are connected to the terminals “+Bat” and ”-Bat”. If two 12 V lead accumulators are present, they
must be connected in series (plus pole of one accumulator to minus pole of the other).
If external buffer accumulators are used, accumulator safeguarding must be performed by the user! For safety
reasons, the safeguarding element (overload and short circuit protection) must be arranged in close proximity
to the accumulator set itself! If lead accumulators are used, sufficient air flow must be provided according to
VDE 0510, part 2.

NOTE
Only use VdS approved lead accumulators. Never use different lead accumulator types, nor lead
accumulators of different manufacturers, nor old and new accumulators together.
CAUTION
Protect, i. e. insulate the poles when connecting lead accumulators. In case of short-circuits
there is the danger of severe burns by arcs or hot parts.
CAUTION
Hydrogen is generated during the charge of lead accumulators, forming dangerous oxyhydro-
gen. Ensure proper ventilation.
CAUTION
The lead accumulator voltage must correspond to the rated voltage of the charge rectifier! Never
confuse the polarity of lead accumulators and never short-circuit lead accumulators!
In case of non-observance there is the danger of severe burns by arcs or hot parts.

NOTE
The lead accumulators must be fixed properly.
Never install unsecured lead accumulators into the unit; danger of short-circuits!
NOTE
If the AKKUTEC is connected in parallal (Master/Slave-operation) the 24 V accumulator lines
must be connected to each other. It is not at all permissible to connect an accumulator line at the
master and the other accumulator Iine only at the slave.
A connection from the plus to the corresponding negative pole is absolutely necessary.
NOTE
Used lead accumulators must be disposed

3.4 Connection of mains voltage
The input voltage of the external energy supply must correspond to the mains voltage at the distribution. The
mains voltage must be disconnected and secured against unintended powering up.
The voltage-free mains cable must be connected to the mains connection terminal provided for this, taking into
account the phase. Mains connection must be performed to the terminals “L1”, “N” and PE ( ).
It is obligatory to connect to operational earth.
3.5 Connection load
When connecting the load , the polarity “+” and “-” must be considered.
If the mains voltage is disconnected, and if the minimum input voltage is fallen short of, the external energy
supply changes over to buffer operation.

NOTE
In case of overload, the DC output current is composed of the maximum charge rectifier cur-
rent and the lead accumulator current. The DC output circuit must be fused externally in order
to avoid overload!
3.6 Signal contacts
The status of the external energy supply can be forwarded to a superior central
unit via signal contacts. The relay contacts are linked to the LED’s with the same
name. Thus, the illumination of an LED effects the corresponding relay.

Fuse board
Fuse boards can be plugged in directly into the power supply or separately mounted on T-rail. Each output is
separately monitored. In case of fuse blow, the corresponding LED goes out and a general error signalizes
the fuse blow to the AKKUTEC. The AKKUTEC transmits the error if it is adjusted correspondingly.
The fuse boards are modular and expandable.

4 Start-Up
The power supply is switched on by the activation of the mains voltage (230 V AC).
DANGER
Check the correctness of the connections prior to the first activation!
Establish electrical connections only in de-energized status!
In case of non-observance, touching live parts can result in death or serious injury.
Two seconds after connection to the mains the connected consumers are supplied. The charge of the lead
accumulators is carried out as well. The charging time is increased if simultanously to the charging current a
high load current is needed, too.
The first lead accumulator test is performed after 60 seconds.
4.1 Display and messages
Four LEDs are installed to indicate the the status of the unit:
Display
Significance
operation
LED green illuminates:
- as long as the output voltage is present.
mains-OK
LED green illuminates:
- at mains operation UE> UEmin
- and Tint < Tintmax
Bat-OK
LED green:
- illuminates:
at UBat > 21.6 V DC
- goes out:
- at UBat < 21.6 V DC
- if the accumulator circuit is interrupted (test interval 1 min)
- if the lead accumulators are reverse poled
- if the Ri accumulator internal resistance is too high (test interval 10 min.)
Error
LED yellow illuminates:
- at back-up operation
- if the accumulator circuit is interrupted
- if the lead accumulator is reverse poled
- if the accumulator internal resistance is too high
- in case of a fuse blow on the fuse board (if activated)
(The LED’s are coupled to the signal contacts which have the corresponding names.)
5 Operation
5.1 Mains operation
Mains operation is indicated with the illumination of the green LED Mains-OK and the green LED Operation.
5.2 Back-up operation
By removing the mains voltage respectively by the underrun of the minimum input voltage, the unit switches
over to back-up operation. The back-up operation is indicated with the illumination of the LED Operation. The
LED Mains-OK does not illuminate.
5.3 Deep discharge protection
Deeply discharged lead accumulators can cause irreversible damage. The final discharge voltage specified by
the manufacturer must never be underrun. In case of a mains failure, the external energy supply continuously
monitors the discharge of the lead accumulators. If the final discharge voltage is reached, the consumers are
automatically disconnected from the lead accumulators by load rejection.

5.4 Accumulator circuit monitoring
In order to ensure the buffer capacity of the external energy supply, the accumulator circuit is tested in cycles
of 60 seconds; the first test is performed 60 seconds after connection to the mains. This test allows the detec-
tion of a possible interruption resp. high resistivity of the accumulator circuit.
In mains operation, a defective accumulator circuit is indicated by the LED Bat-OK going out, and the illumina-
tion of the LED Error.
5.5 Accumulator test
A cyclic lead accumulator test which is performed during mains operation each 10 minutes, stresses the bat-
tery with simultaneous voltage measurement. This allows to give a statement about the internal resistance of
the accumulator.
A severely aged lead accumulator is indicated by the LED Bat-OK going out and the illumination of the
LED Error in mains operation.

NOTE
The lead accumulator test serves to detect severely aged lead accumulators. In order to be able
to make a statement about the buffering ability of the lead accumulators in the present system, a
manual check of the lead accumulators is necessary in regular intervals! (See section 7)
When the AKKUTEC 2412 VdS is delivered it is configurated for three different accumulator dimen-
sions. Herewith the limiting value for the measurement of the internal resistance is adjusted as follows:
1: 7 Ah -18 Ah 225 mΩ
2: 26 Ah -85 Ah 175 mΩ
3: >65 Ah and at Master/Slave operation 125 mΩ

NOTE
The Windows-Software paraTEC VdS is available for the configuration of AKKUTEC for special
requirements.
Special characteristics: Voltage, current, temperature monitoring, adaptation of internal re-
sistance threshold for different lead accumulator sizes, activation/deactivation for external fuse
board.
5.6 Temperature tracking (optional)
Lead accumulators have a temperature coefficient of approximately - 3 mV per °C and per cell.
For the usage without temperature sensor the final charging voltage of the external power supply is selected in
the way that charging the lead accumulators is ensured in a temperature range of 15 °C to 40 °C.
In applications with frequent and strong temperature variations, the charging voltage should be adjusted in
order to obtain maximum life duration of the lead accumulators. A temperature adjustment should be ensured
as well in particular in case of very low ambient temperatures (Tu< 15 °C) in order to ensure sufficient lead
accumulator charge. The temperature tracking is activated automatically by connecting the external tempera-
ture sensor (optional module) to terminal 1and 2of the terminal strip IO-2. Depending on the ambient temper-
ature variation of -10 to 50 °C, the deep discharge voltage (and thus, also the output voltage) varies in a range
of 28.6 V to 26.4 V DC (27.36 V at 25 °C).
A lead accumulator temperature above 45 °C is registered by the power supply and forwarded to the monitor-
ing software paraTEC. The power supply however does not monitor this condition.

NOTE
To ensure a satisfyinglife duration of the lead accumulators, the operating temperature
of the lead accumulators should not exceed 20 °C. Higher temperatures lead to a drastic
decrease of the life duration resp. service life!

NOTE
Die VdS-regulation instructs a temperature tracking. For VdS conform operation a tem-
perature sensor must be connected to the power supply!
