2.4. Hazards from electric power
Installing easily accessible disconnecting device
DLT-V83 industrial PCs are not equipped with disconnecting devices that are
accessible from the outside; they do not have switches. To enable the devices to
be quickly disconnected from the power supply in emergency situations:
 Install an easily accessible disconnecting device,
such as a switch or circuit breaker close to the device.
 Make sure that the disconnecting device disconnects all power supply lines.
Important:
− For DLT-V83 devices with integrated UPS the device may be in operation
despite the disconnecting device being actuated, since it is supplied with
power by the UPS.
− Likewise, the peripherals that are supplied by the device are also not
currentless as long as the DLT-V83 is being provided with power by the UPS.
Disconnecting the DLT-V83 with integrated UPS (optional) from the electric
power source
DLT-V83 industrial PCs with integrated UPS are equipped with lithium-ion
batteries in the cable cover of the device. The internal UPS may still carry current
even if the DLT-V83 itself is switched off.
Reason: If the the DLT-V83 has been configured to also start without <Power>
button and ignition in the "DLoG Config" program, this setting will need to be
changed first. Otherwise, the DLT-V83 will restart after a short pause as long as
there is available battery capacity.
 Shut down the DLT-V83 via the operating system function.
 Disconnect from the power source.
 Open the cable cover.
 Unplug the UPS battery.
Disconnecting the DLT-V83 without UPS from the electric power source
 Shut down the DLT-V83 via the operating system function.
 Disconnect from the power source.
