Connecting DC devices to the power supply
DLT-V83 is available with a galvanically separated, integrated DC power supply. Power is connected to
the back of the device using a Phoenix contact connector. There is no power switch for the mains
voltage.
WARNING
Hazardous voltage, electric shock on the DLT-V83 with DC power supply unit.
Do not put the DLT-V83 into operation if it is damaged.
Do not open or modify the DLT-V83.
Only connect or disconnect electrical connections when the device is in a de-energized
state (electrically dead).
Use only original power supply cables from Advantech. Advantech power cables meet the
specific requirements for low-temperature flexibility, UV resistance, oil resistance, etc.
If other power supply cables are used: The user/operator of the DLT-V83 is solely
responsible for the resulting damage.
Make sure that the power supply cables are run without kinks and are mechanically
protected (securely protected against crushing and abrading).
The DC+ connecting cable must be protected by a fuse (30 AT max.).
The ignition connecting cable must be protected by a fuse of the following type:
5x20 mm T 125 mA L / 250 V, for example, a Wickmann 195-125 mA / 250 V.
Observe correct voltage ranges.
Ensure that power supply cable is fused correctly.
Observe the labeling on the cable and connect the power supply cable with the correct
polarity.
Cut the supply cable to the minimum length. This avoids tangled cables and improves the
quality of the power supply.
Connect the power supply cable to a suitable place. Ensure that the connecting cable has
an adequate cross section and ampacity at the connection point.
DLT-V83 Industrial Computers with DC power supply unit may only be connected to a
SELV circuit (Safety Extra Low Voltage).
