13.1.2. Power cables and fuses

WARNING
DLT-V72 Series User Manual V2.70
Electric shock, fire due to incorrect cable routing or
insufficient grounding.
1. Use only original Advantech power cables; these meet the
specific requirements for low-temperature flexibility, UV
resistance, oil resistance, etc.
2. Make sure that the power supply cables are run without kinks
and are protected (securely protected against crushing and
abrading).
3. 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.
4. The DC+ connecting cable must be protected by a fuse (30 AT
max.).
5. 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.
6. Observe correct voltage ranges.
7. Ensure that power supply cables are fused correctly.
8. Read the labeling on the cable and connect the power supply
cable with the correct polarity.
9. Cut the supply cable to the minimum length. This avoids
tangled cables and improves the quality of the power supply.
10. 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.
