Information about this manual
Read this manual carefully before starting to use the device. Keep the manual
so you can refer to it at a later date if you need to. If you hand over the
device to other persons for use, please hand over this manual as well.
Symbols used:
Attention! This indicates a hazard.
Please note: This section contains important additional information.
Hazard information
Do not open the device. It does not contain any parts that can be maintained
by the user. If you have any doubts, have the device checked by an expert.
For safety and licensing reasons (CE), unauthorized change and/or modification
of the device is not permitted. Do not use the device if there are signs of
damage to the housing, control elements or connecting sockets, for example. If
you have any doubts, have the device checked by an expert.
The device may only be operated in dry and dust-free environment and must be
protected from the effects of moisture, vibrations, solar or other methods of
heat radiation, cold and mechanical loads.
The device is not a toy; do not allow children to play with it. Do not leave
packaging material lying around. Plastic films/bags, pieces of polystyrene,
etc. can be dangerous in the hands of a child.
We do not assume any liability for damage to property or personal injury
caused by improper use or the failure to observe the hazard information. In
such cases, any claim under warranty is extinguished! For consequential
damages, we assume no liability!
The device may only be used for fixed installations. The device must be
securely attached within a fixed installation.
The device is part of the building installation. The relevant national
standards and directives must be taken into consideration during planning and
set-up. The device has been designed solely for operation on a 230 V/50 Hz AC
supply. Only qualified electricians (to VDE 0100) are permitted to carry out
work on the 230 V mains. Applicable accident prevention regulations must be
complied with whilst such work is being carried out. To avoid electric shocks
from the device, please disconnect the mains voltage (trip the miniature
circuit-breaker). Non-compliance with the installation instructions can cause
fire or introduce other hazards.
Exceeding this capacity could lead to the destruction of the device, fires or
electric shocks. Please take the technical data (in particular the maximum
permissible capacity and the type of load to be connected) into account before
connecting a load. All load data relates to ohmic loads. Do not exceed the
capacity specified for the device.
The device may only be operated within residential buildings.
Using the device for any purpose other than that described in this operating
manual does not fall within the scope of intended use and shall invalidate any
warranty or liability.
Function
Devices with electronic power supply units (e.g. TV or high voltage LED light
sources) as well as loads (e.g. fluorescent lamps or energy-saving lamps) can
generate inrush currents with more than 100 A. If these loads are switched via
a relay, for example via the relay of a switch actuator, it can lead to
premature wear of the device. Under unfavourable conditions, high inrush
currents can cause the relay contacts to stick together and lead to failure of
the circuit.
Via an integrated resistor, the inrush current limiter ESB1 reduces
potentially occurring high inrush currents so far that the relay contacts of
e.g. actuators are effectively protected.
If the inrush current limiter is for example used in connection with
conventional incandescent lamps, the lifetime of an incandescent lamp can be
extended while at the same time the switching relay of an actuator is
protected.
The inrush current limiter is not suitable for fast periodic switching. The
pause time between a switching operation should be longer than 30 seconds in
any case. In case of shorter switching periods there is the danger that the
inrush current limiter is not working.
Start-up
Please read this entire section before starting to install the device.
Please note! Only to be installed by persons with the relevant electro-
technical knowledge and experience!*
Important note!
When selecting a mounting location, make sure that a touch protection is
guaranteed. The circuit must be installed in a closed system.
Incorrect installation can put
- your own life at risk;
- and the lives of other users of the electrical system.
Incorrect installation also means that you are running the risk of serious
damage to property, e.g. because of a fire.
You may be personally liable in the event of injuries or damage to property.
Contact an electrical installer!
*Specialist knowledge required for installation:
The following specialist knowledge is particularly important during
installation:
-
The “5 safety rules” to be used:
Disconnect from mains; Safeguard from switching on again; Check that system is deenergised; Earth and short circuit; Cover or cordon off neighbouring live parts; -
Select suitable tool, measuring equipment and, if necessary, personal safety equipment;
-
Evaluation of measuring results;
-
Selection of electrical installation material for safeguarding shut-off conditions;
-
IP protection types;
-
Installation of electrical installation material;
-
Type of supply network (TN system, IT system, TT system) and the resulting connecting conditions (classical zero balancing, protective earthing, required additional measures etc.).
Installation may only take place in normal commercial switch boxes (device
boxes) in accordance with DIN 49073-1 or surface-mounting boxes in accordance
with DIN 60670-1 (e.g. Abox 025 or Abox 040).
Please note that the inrush current limiter may only be switched in series to
a load and not parallel to the power supply.
To install the inrush current limiter, please proceed as follows:
- Switch off the fuse of the power circuit.
- Remove the actuator from the flush-mounted or surface-mounted box.
- Loosen the output terminal of the actuator (connecting terminal for L’) and then pull the wire out of the terminal.
- Connect one of the two wires of the inrush current limiter to the connecting terminal for L’.
- Connect the other wire of the inrush current limiter using a suitable terminal with the phase conductor from the connecting terminal for L’ of the actuator.
- Reinsert the inrush current limiter and the actuator back into the flush-mounted or surface-mounted box.
- Close the flush-mounting or surface-mount box using an appropriate cover.
- Switch the fuse of the power circuit back on again.
Here disconnect the phase conductor, that provides power supply for the load,
at a suitable place. Then connect the wire to the actuator with a wire of the
inrush current limiter and the wire to the consumers with the other wire of
the inrush current limiter.
When exceeding the maximum permissible connected load of 200 W or in case of a
short-circuit of the load, the integrated safety fuse of the inrush current
limiter is tripped and the inrush current limiter must be replaced.
Maintenance and cleaning
The product does not require any maintenance.
Enlist the help of an expert to carry out any maintenance or repairs.
