2. Safety instructions
2.1 Maintenance free / pressure relief valves
The sealed battery blocks require no maintenance. Topping up with water is not allowed. Pressure relief valves are used
as stoppers. Opening them results in the destruction of the battery.
However, the battery requires regular inspection and maintenance (see Section 7).
2.2 Prohibitions, requirements and disposal instructions

Pb
1 Observe the Instructions for Use.
2. When working on batteries wear protective glasses and clothing as
specified in the Accident Prevention Instructions and DIN/EN
50272-2 (VDE 0510).
3. Smoking is forbidden, no naked flames, embers or sparks are
allowed in the vicinity of the battery.
4. There is a danger of explosion and fire so avoid short circuits. Metal
parts of the poles are always live, therefore do not put tools or other
items on the battery.
5. The electrolyte, sulphuric acid, is very corrosive. There is no possi-
bility of contact with the electrolyte unless the battery is damaged
If the casing is defective the electrolyte retained in the
fleece behaves like liquid electrolyte.
6. Any droplets of acid that gets into the eye or on the skin
must be rinsed out or washed off immediately with a
copious supply of water. Then get to a doctor without
delay. If clothing is polluted wash it immediately with
water.
7. Block batteries are heavy. Take care to put them on a
safe base. Only use suitable transport equipment.
8. Old batteries with this sign can be recycled and must be
put through the recycling process. Old batteries, which
are not put through the recycling process should be
disposed of in accordance with all the regulations as
special waste products.
3. Storage
All battery blocks are delivered in the charged condition. If they are not to be put into service immediately but are to be put in store
for a long time they should be stored in a dry, clean and frost free place. Sealed lead acid batteries are best given a trickle charge
when stored. If this is not the case, they must be given an equalisation charge (see Section 6.1.4) at the latest when they sink to
12.5 V open circuit voltage, or every 6 months depending on which occurs first.
4. Commissioning
The ideal operating temperature is 200C. Higher temperatures shorten the life of the battery, lower temperatures reduce
the available capacity. The battery blocks must be so set up, that within the same blocks temperature differences of >30 C cannot
occur. Before commissioning, the batteries should be examined for damage, correct pole connection, solid fit of the connectors (for
torques see table above) and secure contacts. If necessary, pole covers should be fitted. After the charging device and loads are
switched off the correct poles of the battery should be connected to the d.c. supply. Switch on the charging device and charge the
battery as specified in Section 6.1.
The regulations in DIN/VDE 0107, DIN/VDE 0108, DIN/EN 50272-2 (VDE 0510-2) or DIN/VDE 0510-7 as well as IEC 896-2
(DIN/EN 60896-2) should be observed if necessary.

Emergency power lamp Dr. Mach
Lamps and Engineering
59520002_e Edition 13 22.02.2013 / Bak Page 4/25
5. Operation
The regulations of DIN/VDE 0107, DIN/VDE 0108, DIN/EN 50272-2 (VDE 0510-2) or DIN/VDE 0510-7 as well as IEC 896-2
(DIN/EN 60896-2) should be observed when operating static sealed batteries.
6 Charging, discharging
6.1 Charging
Any of the charging procedures with their limits as specified in DIN 41773 (IU-characteristic), DIN 41774 (W-characteristic) or DIN
41776 (I-characteristic) can be used. Depending on the equipment the batteries in this equipment are charged with the IU-
characteristic.
6.1.1 Maintaining the full load condition (maintenance charge)
Equipment with the properties specified in DIN 41773 (IU-characteristic) should be used. The equipment should be so set up, that
the cell voltage(20°C) = 2.3 V/cell (permissible deviation: 1%). If the battery temperature is continuously higher or lower due to
higher or lower environmental temperature, the charging voltage must be adjusted to:
Charging voltage (more than 20°C) = 2.3 V/cell - 0.004 V T (T = Temperature difference above 20°C)
Charging voltage (less than 20°C) = 2.3V/cell + 0.004 V T (T = Temperature difference below 20°C)
Example: Temperature lies predominately at 15°C, charging voltage = 2.3 V/cell + 0.02V/cell = 2.320 V/cell. Temperature lies
predominately at 30°C, Charging voltage = 2.3V/cell - 0.040 V/cell = 2.260 V/cell.
6.2 Discharging
The correct discharging currents are obtained from the capacities as specified in I(Disch..) = Ct/t. Unless other data is available, not
more than the correct capacity can be taken out. In order to avoid a deep discharge and consequent destruction of the battery, it
must be disconnected from the loads before reaching the discharge finishing voltage that is dependent on the bridging time.
Guide values are:
Bridging time Discharge finishing voltage Bridging time Discharge finishing voltage
> 3 h 1,80 V/cell 20 min. – 1 h 1,67 V/cell
1-3 h 1,75 V/cell < 20 min. 1,60 V/cell
The connection of the loads should only be done after the power supply has been restored. After discharge, even partial dis-
charge, the battery should immediately be charged.
7. Battery maintenance, inspection of the battery equipment
7.1 Battery maintenance
The battery should be kept clean and dry in order to prevent leakage currents. The cleaning of the battery should be done in
accordance with the ZVEI-leaflet “Cleaning of batteries“. Plastic parts of the battery may only be cleaned with clean water.
7.2 Inspection of battery equipment
It is recommended that every 3 months the following work should be done and documented:
Visual inspection of the battery regarding cleanliness, damaged battery blocks and loose contacts
Measurement of charge maintaining voltage of the battery and the individual battery blocks
Measurement of the surface temperature of the battery blocks
Measurement of the temperature in the battery room.
The following work should be carried out and documented at least every 12 months (guarantee condition):
All connections should be tightened to the recommended values (see table under Item 1) by a torque spanner,
The tests for 6 months should be repeated
If possible, measure the voltage of the battery and the individual battery blocks with the charging device switched off.
Only in collaboration with the System Manufacturer or someone authorised by him:
Record the battery block voltages during the discharge of the battery (capacity test).
When tests are carried out they should be done as specified in IEC 896-2 (DIN/EN 60896-2). Instructions specified in DIN/VDE
0107 and DIN/VDE 0108 should also be observed.
8. Guarantee
Guarantee claims are only accepted if the maintenance and servicing work have been properly carried out. For guarantee claims
at least the following data/documents must be provided: the reason for the complaint, contract number and the last two mainte-
nance reports. Defective battery blocks must be sent back for defect analysis carriage paid.
If the Instructions for Use are not followed, e.g. if the room temperature is too high, the batteries are left discharged for a
long time or stored in unsuitable conditions, trickle charged at the wrong voltage or the service intervals and instructions
are not observed, the guarantee becomes invalid.

8.2.2 Adjusting the spring force
It is only possible to balance the weight when the
distance between ceiling and bearing journal ex-
ceeds 40cm. For low ceilings and consequently
short suspension tubes, the drilled nut in the articu-
lated arm described below which is required for the
balancing procedure is not visible. The procedure
for balancing the weights must in this case be car-
ried out by Dr. Mach or someone authorised by Dr.
Mach.
Spring arm for light weighted central axis
Gently spread the lateral circular surfaces 1of the
cover cap and pull the cover cap forwards (other-
wise risk of breaking the snap hook)
Take out the clamped in socket key (in the cover
cap).
Move the spring arm into a position in which the
hole nut is visible.
Notice: If the max. height of the spring arm is
limited the hole nut may in certain circumstanc-
es remain invisible. In this case consult your
dealer or Dr. Mach directly.
Place the key bolt which can be found below the
cover on the top of the spring arm in the hole nut
and turn accordingly.
Use only the enclosed key bolt since a screw-
driver could break.
Proceed as follows depending on the movement of
the light:
- Light moves down on its own - turn bolt in the
direction of the "+" mark.
- Light moves up on its own - turn bolt in the
direction of the "-" mark.
Then clamp the socket key in the cover cap and
place the cap back on the articulated arm.

9. Properties
The device is designed for supplying 24V-consumers, which have to be suitable for alternating cur-
rent AC and for direct current DC.
A safety low voltage SELV according to DIN VDE 0100, T. 410 is available for a maximum power
consumption of 170W.
In case of power failure the device has a service life of approx. 2,5 to 3 hours in conditions of maxi-
mum power consumption.
The functions of the device run automatically, for example the switch-over function between die mains
operation and battery operation and reverse.
The device is designed and built according to the regulations of the DIN VDE 0107. Due to its
size, power consumption and request for mobility it is not possible to satisfy every parameter
of the DIN VDE 0100-710. Therefore the range of use is the decision of the client.
10. Location
The device is designed according to the protection type IP 20. The device is to be used only at dry
and roofed over locations.
It is not allowed to cover the ventilation slots. It is not allowed that dirt and other foreign substances
infiltrate into the device.
The environmental temperature should be between 10°C and 25°C.

The green LED „MAINS“ is burning now. The green or yellow LED of the „LEVEL“ – marking is also
burning. The LED „BATTERY FAIL“ turns off.
The output of the unit is supplied with 24 V.
Because of safety reasons this voltage can not be switched off.
The unit must now be supplied continuously from mains. Do not turn the unit off, except special cas-
es!
13. Mains operation
As long as the unit is supplied from mains, the lamp will be supplied by the built-in transformer.
During normal operation status the green LED „MAINS“ is burning, the batteries are charged auto-
matically and they keep their full-charged-status.
14. Battery operation
If the mains voltage decreases to values under 85% of the rated voltage, the unit automatically
switches over to battery operation, and the lamp is supplied with battery current. This status is shown
as follows:
oThe green LED „MAINS“ turns off.
oThe red LED „MAINS FAIL“ is burning.
oThe yellow LED „BATTERY“ that shows battery current, is burning.
oThe acoustic signal is buzzing – this signal can be switched off by pressing touch-button
„BUZZER OFF“.
oThe battery’s state-of-charge is shown by the LED’s of the „LEVEL“ – monitor.
When the batteries are fully charged, the lighting time is approx. 3 hours.
If there is no mains voltage available until the battery is empty, the built-in low-discharge-protection
disconnects the lamp from the battery. The LED „BATTERY FAIL“ is burning.
If the mains voltage increases to values over 95% of the rated voltage, the unit automatically switches
over to mains operation and the batteries are charged. The LED „BATTERY FAIL“ turns off.
ATTENTION! After a disconnection by the low-discharge-protection the next battery operation is
possible only after several hours of mains operation and battery charging! It has to
be tested, if the unit is ready for another line failure.
After battery operation / line failure the unit must be supplied with mains voltage
and the batteries must be charged as soon as possible.

15. „TEST“-operation
Before every use (on every day) the status of the unit must be checked by pushing touch-button
„TEST“. A line failure with battery operation, as described above, will be simulated for approx. 5 sec-
onds.
During this time the green LED at the „LEVEL“ – monitor must burn continuously and the yellow or
the red LED must remain off. The batteries must be fully charged for this operation.
If the unit does not function as described above, the cause must be found and the possible damage
must be repaired. It may be necessary to replace the batteries or even to change the whole unit.
Every three months it is necessary to simulate a longer line failure (1 to 2 hours) by disconnecting the
unit from mains, in order to test the capacity and lighting time of the batteries. The „LEVEL“ – monitor
should be observed during the operation and the parameters should be kept for further comparisons.
In case the lighting time is under the minimum of 2 hours, the batteries must be replaced.
16. Remarks concerning the batteries
Avoid low discharges! The red LED „BATTERY FAIL“ should not burn.
After discharges ensure mains operation as soon as possible, so the batteries can be charged.
Avoid high operation temperatures.
Batteries are working parts. They must be replaced after their life time, even if they didn’t function.
Only use batteries of the same type and the same design. The original batteries can be ordered at the
manufacturer.
17. „BUZZER OFF“
In case of line failure or TEST- operation the acoustic signal is activated. The signal can be turned off
by pushing touch-button „BUZZER OFF“.
18. Turning OFF the unit
When the unit is turned OFF for a longer time (without mains voltage), first charge the batteries, so
they are fully charged.
Then remove the battery fuse at the back side of the battery box, turn OFF the unit at the ON/OFF
switch and unplug from mains. The batteries are no longer charged now.
The unit can be stored for max. 2 months.
After max. 2 months the unit must be reconnected to the mains and the batteries must be charged for
min. 24 hours (see also chapter “First use”).
