Installation And Connection; Setting The Output Voltage - BASETech 1599558 Mode D'emploi

• Maintenance, adjustment and repair work should only be carried out
by an expert or a specialist workshop.
• If you have any questions that are not answered in these operating
instructions, please contact our technical customer service or other
technicians.
b) Installation/connection
• The construction of the product corresponds to the protection-class
II (double or reinforced isolation). Ensure that the insulation of the
housing is neither damaged nor destroyed.
• During installation, all poles must be disconnected from the mains
voltage, e.g., via RCD. There must be an appropriately dimensioned
fuse or circuit breaker between the RCD and the product.
• The device must be voltage-free during installation and connection.
Furthermore, turn off the automatic circuit breaker and the earth leak-
age circuit breaker to disconnect all the poles from the mains voltage.
Secure it against unauthorised reconnection, e.g., with a warning
sign. Check to make sure there is no voltage with a suitable measur-
ing instrument (e.g., a digital multimeter).
• Never connect the product to the power supply immediately after it
has been transferred from a cold room into a warm one (e.g., dur-
ing transport). The condensation that forms might destroy the device.
Moreover, there is danger of electric shock!
Allow the product to reach room temperature. Wait until the conden-
sation has evaporated. This might take several hours. Only after this,
should it be installed, connected to the mains supply and put into use.
• Do not use the product in rooms with adverse environmental condi-
tions, where combustible gases, vapours or dust are or may be pre-
sent! There is a danger of explosion!
c) Operation
• Use the product only when it is firmly and steadily mounted.
• Make sure you use a suitable electric shock protection for the con-
necting terminals and the power cables.
• Use the product only in a temperate climate, never in a tropical cli-
mate.
• Do not use the product if it is damaged. There is a risk of a life-threat-
ening electric shock!
• If it can be assumed that safe operation is no longer possible, the
product must be turned off and precautions are to be taken to ensure
that it is not used unintentionally. Do not touch the product.
First switch off the mains voltage to all poles (switch off the connected
circuit breaker or remove the fuse and then switch off the connected
RCD).
After this, arrange for a skilled electrician to check the product.
• Safe operation can no longer be assumed if:
- the product shows visible signs of damage
- the product does not work at all or well (flickering light, leaking
smoke or a smell of burning, the light flickers, audible cracking
noises, discolouration to the product or the adjacent surfaces.)
- the product was stored under unfavourable conditions

Installation and connection

It is important that you read these operating instructions, including the
safety instructions thoroughly and carefully before first use to ensure
that you will launch the relay board properly! If in doubt, let a specialist
do the installation and connection.
Only connect boards when they are disconnected from voltage/current.
Otherwise, there is a risk of a life-threatening electric shock!
If the product is to be installed in an electrical control cabinet, or similar,
where dangerous voltages are present, do not carry out the connection
and installation yourself; rather, have it done by a qualified specialist
(e.g., electrician) who is familiar with the regulations and safety precau-
tions. Otherwise, there is a risk of a life-threatening electric shock!
• Place the power supply unit on the top hat rail. To do this, you have to mount the
power supply unit on the top side of the top hat rail and to fold it down until the
clamping bolt engages.
The clamping bolt on the backside of the power supply unit must point
downwards.
When removing the power supply from the top hat rail, move the tie bar down us-
ing a suitable flat screw driver. The power supply can then be folded upwards and
removed from the top hat rail.
The top hat rail must comply with EN55022 (total width 3.5 cm, total
height 0.75 or 1.5 cm; TS 35/7.5 or TS 35/15). The power supply cannot
be installed on any other top hat rails!
Only one installation position is permissi-
ble: the inscriptions on the front must not be
turned upside down (the clamping bolt on the
backside of the power supply unit points down-
wards, see arrow in the picture on the right)
Ensure sufficient distance to other devices
(5 mm left/right, 40 mm above and 20 mm be-
low the power adapter) to ensure optimal heat
dissipation.
• Connect the direct current output of the power supply to the respective devices.
In so doing, always pay attention to the correct polarity (observe plus/+ and
minus/-; see label on the power supply). Strip approx. 7 mm from the end of
the cables.
• Finally, connect the power cable (N = neutral wire, L = phase, see inscription
"AC N" and "AC L" on the power supply). Strip approx. 7 mm from the end of
both cables.
• Before switching on the power supply, the electric shock protection must be es-
tablished (e.g. re-attach covers in the control cabinet, etc. so that the screw
clamps are covered and only the small rectangular front of the power supply is
accessible).
• After switching on the power supply, the control LED lights up to indicate its
function.

Setting the output voltage

The power supply unit is factory set to the nominal output voltage (12 V/DC resp.
24 V/DC, depending on the version).
If the cable between the power supply and the consumer is very long, the voltage
may drop. The consumer does not receive the nominal output voltage.
In this case, you can set the output voltage with a rotary potentiometer. Use a VDE-
tested screwdriver to adjust the setup.
For item no. 1599558, 1628895
Turning to the left in a counter-clockwise direction will increase the output voltage,
while turning to the right in a clockwise direction will decrease the output voltage.
