Operating conditions
The operation of the assembly group can take place only on condition of observing the required voltage and the
ambient conditions. The operating position of the device is irrelevant. The device is meant to be used in dry
areas free of dust.
Should condensed water build up within the sensor, an acclimatization period of at least 2 hours must be met.
The components can be operated only under the supervision of an electrically skilled person. Assembly groups
and components do not belong into the hands of children.
In industrial facilities, the accident prevention regulations of the federation of industrial professional associations
for electrical installations and equipment must be observed.
Do not operate the components in an environment with inflammable gases, vapors or dusts or in an environment
where such gases, vapors or dusts may occur.
13
Assembly
The mounting place must be protected against moisture. The module may only be used in dry indoor rooms or in
protected outside areas. The device is designed for fixed installation within a switching cabinet.
14
Disposal Note
Do not dispose of this device in the household waste. Electronic devices must be disposed
in accordance with directives for disposing of waste electrical and electronic equipment at
local collection points for electronic waste material.
15
Safety Instructions
When using products that come into contact with electrical voltage, the valid VDE regulations must be
observed, especially VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860
All final or wiring work must be carried out with the power turned off.
Before opening the device, always unplug or make sure that the unit is disconnected from the mains.
Components, modules or devices may only be put into service if they are mounted in a contact proof housing. During
installation they must not have power applied.
Tools may only be used on devices, components or assemblies when it is certain that the devices are disconnected
from the power supply and electrical charges stored in the components inside the device have been discharged.
Live cables or wires to which the device or an assembly is connected, must always be tested for insulation faults or
breaks.
If an error is detected in the supply line, the device must be immediately taken out of operation until the faulty cable
has been replaced.
When using components or modules it is absolutely necessary to comply with the requirements set out in the
accompanying description specifications for electrical quantities.
If the available description is not clear to the non-commercial end-user what the applicable electrical characteristics
for a part or assembly are, how to connect an external circuit, which external components or additional devices can
be connected or which values these external components may have, a qualified electrician must be consulted.
It must be examined generally before the commissioning of a device, whether this device or module is basically
suitable for the application in which it is to be used.
In case of doubt, consultation with experts or the manufacturer of the components used is absolutely necessary.
For operational and connection errors outside of our control, we assume no liability of any kind for any resulting
damage.
Kits should be returned without their housing when not functional with an exact error description and the
accompanying instructions. Without an error description it is not possible to repair. For time-consuming assembly or
disassembly of cases charges will be invoiced.
During installation and handling of components which later have mains potential on their parts, the relevant VDE
regulations must be observed.
Devices that are to be operated at a voltage greater than 35 VDC / 12mA, may only be connected by a qualified
electrician and put into operation.
Commissioning may only be realized if the circuit is built into a contact proof housing.
If measurements with an open housing are unavoidable, for safety reasons an isolating transformer must be installed
upstream or a suitable power supply can be used.
After installing the required tests according to BGV A3 / Betriebssicherheitsverordnung must be performed.
