WARNING
Electric shock, fire due to incorrect cable routing or insufficient grounding.
Use only original Advantech power cables; these meet the specific requirements for low-
temperature flexibility, UV resistance, oil resistance, etc.
Make sure that the power supply cables are run without kinks and are protected (securely
protected against crushing and abrading).
The DLT-V72 may only be connected to a SELV circuit (Safety Extra Low Voltage). The
SELV circuit is a secondary circuit that is designed and protected so that its voltages will
not exceed a safe value both when operating correctly or if a single error occurs.
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 cables are fused correctly.
Read 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.
