Connecting Power Supply

The external wiring consists of the connection of the power supply, the
battery pack (optional) and the connection of customized components for
shutting down the PC.

Cable Cross Sections

For the connection of the power supply, wiring with a cable-cross-section of

1.5 mm2 must be used.
With bigger distances between voltage source and PC, you take the

voltage drop as a function of the cable-cross-section as well as voltage
fluctuations of your distribution voltage into account, so that is secured that
the voltage doesn't fall under 22 V at the power supply.

The power supply must be protected with maximum 16 A.

Configuration for shutting down the PC

The connections for shutting down the Industrial PCs are established via
the PC_ON input and the Power Status output.

PC_ON and Power Status functions

• If the PC_ON input is connected to 24 V via a switch, the PC shuts

down according to the rules. The PC_ON signal is inverted, i.e. the
PC shuts down if the 24 V connection is live.

• If the PC_ON input is NOT connected by the user, the PC can be

booted in the familiar way by connecting the supply voltage and
shut down via the battery by switching off the supply voltage.

This procedure significantly reduces the service life of the
rechargeable battery and should therefore not be used.

• Once the PC has shut down, the Power Status output is switched

from 24 V to 0 V. Via this output a signal lamp can be connected or
a contactor for de-energizing the whole system. The maximum
load for the Power Status output is 0.5 A and a suitable fuse
should be provided.

UPS output

In order to maintain a screen display for the PC in the event of a power
failure, the power supply unit is equipped with a UPS output for connecting
a Control Panel. The maximum load for the output is 1.4 A (max. 2.5 A
from 2016 and later).

UPS output function

• The 24 V DC connection at the UPS output is live even after a

power failure. The maximum load is 1.4 A (max. 2.5 A from 2016
and later).

• Once the PC has been de-energized via the UPS software, the

UPS output is switched to 0 V. Any connected panel is thus
switched off, and total discharge of the rechargeable battery is
prevented.

With compact 100-240 VAC 50/60 Hz power supply:

1. Check that the mains voltage is correct.

2. Insert the power supply cable that you have assembled (see the

section on Fitting the Power Supply Cable) into the Industrial PC's
power supply socket. Then connect it to a power socket with a
grounded earth connection.

When fitted with the (optional) 24 VDC power supply unit:

1. Check that the external power supply is providing the correct

voltage.

2. Insert the power supply cable that you have assembled (see the

section on Fitting the Power Supply Cable) into the Industrial PC's
power supply socket. Then connect it to your external 24 V power
supply.

Operating Instructions

Switching the Industrial PC on and off

Switch on

The Industrial PC does not have its own mains switch. The Industrial PC
will start when the equipment is switched on, or when it is connected to the
power supply.

Shutting down and
switching off

When the plant is switched off, or when it is disconnected from its power
supply, the Industrial PC will be switched off.

Control software such as is typically used on Industrial PCs permits various
users to be given different rights. A user who may not close software may
also not switch the Industrial PC off, since data can be lost from the hard
disk by switching off while software is running.

Warning

First shut down, then switch off the PC!

If the Industrial PC is switched off as the software is writing a file to the
hard disk, the file will be destroyed. Control software typically writes
something to the hard disk every few seconds, so that the probability of
causing damage by switching off while the software is running is very high.

Warning

When you have shut down the Industrial PC, you have to switch off power
supply for at least 10 seconds before rebooting the system.
After resetting power supply the PC will start booting automatically.

First switching on and driver installation

When you switch on the Industrial PC for the first time, the pre-installed
operating system (optional) will be started. In this case, all the required
drivers for any additional, optional hardware components ordered with the
PC will already have been installed.

If the PC was ordered without operating system, you have to install the
operating system and the driver software for any auxiliary hardware
yourself. Please follow the instructions in the documentation for the
operating system and the additional devices.
