7 INFORMATION ON SAFE ELECTRICAL INSTALLATION
Danger of electric shock
− Do not put the DLT-V83 into operation if it is showing damage.
− Do not open or modify the DLT-V83.
− If the DLT-V83 with AC power supply unit is opened while it is connected to the
power supply, there is a danger of death due to electric shock!
− Only connect or disconnect electrical connections when the device is in a de-
energized state.
− Use only original Advantech power supply cables; these meet the specific
requirements for low-temperature flexibility, UV resistance, oil resistance, etc.
Installing the disconnecting device
The DLT-V83 is not equipped with disconnecting devices that are accessible from the
outside; it does not have switches.
− To allow the device to be quickly disconnected from the power supply in emergency
situations, install an easily accessible disconnecting device close to the device and
ensure that the disconnecting device isolates all supply lines.
Power supply unit fuse blows repeatedly
If the fuse of the integrated power supply units blows again immediately after
replacement, there is a danger of electrical shock:
− Send in the DLT-V83 immediately for repair.
DLT-V83 with DC power supply unit
− Only connect devices with DC power supply unit to Safety Extra Low Voltage
(SELV) circuits.
− 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.
