the bracket breaks (e.g. because of a
stress fracture).
 Alternatively please put appropriate

Important information for electrical
installation
WARNING
Electrical shock due to lack of
disconnecting device.
DLT-V4108 industrial PCs are not equipped
with disconnecting devices that are
accessible from the outside; they do not have
switches. To enable the device to be quickly
disconnected from the power supply in
emergency situations:
 Install an easily accessible
disconnecting device close to the
device.
 Make sure that the disconnecting
device disconnects all power supply
lines.
Electrical shock due to insufficient
EMERGENCY shut-off mechanism
If the application site’s EMERGENCY-OFF of
does not switch off DLT-V4108, there is a risk
of causing electrical shock.
 Install the application site’s
EMERGENCY-OFF switch and the
DLT-V4108 so that DLT-V4108 is
switched off as well when the
EMERGENCY-OFF switch is operated.
Power supply cable and grounding
WARNING
Electrical shock, fire due to incorrect cable
routing or insufficient grounding.
 Use only original Advantech-DLoG
power supply cables; these meet the
specific requirements for low-
temperature flexibility, UV resistance,
oil resistance, etc.
 Make sure that the power supply
cables are running without kinks and
securely protected against crushing
and abrading.
 DLT-V4108 may only be connected to
a SELV circuit (Safety Extra Low
Voltage).
 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 range.
 Ensure that the power supply cables
are fused correctly.
 Read the label on the cable and
connect the power supply cable with
correct polarity.
 Cut the power supply cable to the
minimum length. This avoids cables
getting tangled and improves the
quality of 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.
