7.7. Connecting AC devices to the power supply
An integrated, electrically isolated AC power supply unit is available exclusively for the
DLT-V8315 (optional).
The power is connected to the AC power supply unit on the underside of the device using an
angled power connector for non-heating apparatus.
The cable of the angled power connector is equipped with an On/Off-switch for the power grid.
DANGER
Danger to life due to hazardous voltage, electric shock on the DLT-V83 with AC power
supply unit.

Do not put the device into operation if it is damaged.

Do not open or modify the device.

There is a danger to life if the device is opened while it is connected to the power supply!

Only connect or disconnect electrical connections when the device is in a de-energized
state (electrically dead).

When using the AC adapter, make sure that the sum of the current consumption of the
system, including the consumers connected via I/O (e.g. scanner) does not exceed the
maximum current of the AC adapter, including its supply lines.
7.7.1. Electrical installation of AC devices
When the DLT-V8315 is installed with an AC power supply unit, the electrical potentials must be
taken into account.
The DLT-V8315 is connected to protective ground by means of the power connector for non-
heating apparatus.
In the DLT-V8315, protective ground, logic ground and shield ground are permanently
interconnected.
Logic ground is the ground (GND) used to supply the internal parts and components such as the
display or CPU.
All cable shields and the housing are connected to shield ground.
If the terminal is connected to other devices or machines via the existing interfaces (USB, serial,
Ethernet, etc.), ensure that the potential of the relevant protective ground is as equal as possible
(equipotential bonding strip).
Leakage currents (compensating currents) can occur here that may cause random restarts,
malfunctions or even the destruction of the device or peripheral devices.
If you want to connect devices fed by other power sources to the DLT-V8315 (e.g. printers), be
sure to power up the peripheral devices at the same time or after the DLT-V8315; otherwise, you
may encounter start-up problems or malfunctions and there may even be irreparable damage to
the device.
