Note

The power supply unit must only be used in conjunction with Beckhoff
Industrial PCs!

Switch off the power supply of the system during installation!

Attention

During assembly, removal and electrical wiring of the power supply unit,
the power supply of the system must be switched off in order to prevent
damage on the power supply unit and the Industrial PC.

Items of equipment that have been switched off must be secured against
being switched on again.

Do not open the power supply unit while voltage is applied!

WARNING

The supply voltage must be switched off before the power supply unit
housing is opened.

Operator's obligation to exercise diligence

Product Description

Appropriate Use

The C9900-P223 and C9900-P224 power supply unit provide the power

supply for Beckhoff Industrial PCs.
The C9900-P224 power supply in conjunction with a C9900-U330 b attery

pack allows the construction of an uninterruptible power supply (UPS).

Beckhoff power supply technology

Innovative solution for
shutting down Industrial
PCs

C9900-P223 / C9900-P224 5

Industrial PCs equipped with a UPS are in actual use frequently switched
off by simply turning off the supply voltage. In this case the PC shuts down
via the battery. However, over time this reduces the service life of the
battery.

The new Beckhoff power supply technology approach addresses this
problem and now offers the user the option of switching the PC off without
the need for using the battery, thereby reducing the load on the battery.

In addition to the main switch this innovative solution uses an ON/OFF
switch for the machine. Basically, the main switch remains switched on and
provides the power supply for the PC during shutdown. Via the PC ON­input of the power supply the PC gets the command to shut down the
operating system.

Once the PC has shut down, the PC power supply unit sets the Power
Status-output (P-S) to 0, what indicates that the process is complete and
that the main voltage can be switched off. This can be done manually via a
signal lamp connection or via a contactor. With this solution the main

Product Description

switch generally only has to be switched off if the control cabinet has to be
opened. The battery will only be used in the event of a power failure.

In order to maintain a screen display for the Industrial PC in the event of a

power failure, the C9900-P224 power supply unit is equipped with a UPS
output 27 V / 1.4 A for connecting a Control Panel with a display dimension
up to 19 inches. This enables a power failure to be visualized and
displayed to the user. Once the PC has shut down, the UPS output is
switched off.

For a detailed functional description please refer to section External wiring.

battery pack (only C9900-P224) and the connection of customized
components for shutting down the PC.

The external wiring occurs according to the wiring diagram, see chapter

Wiring diagram.

Cable Cross Sections

Note cable cross sections,
avoid voltage drop!

For the connection of the power supply, wiring with a cable-cross-section
of 1.5 mm

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.

Insert fuse

must be used.

Attention

The power supply must be protected with 16 A.

PC_ON and Power Status functions

Attention

 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.

Service life of the rechargeable battery

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.

Installation Instructions

UPS output, C9900-P224 only

In order to maintain a screen display for the PC in the event of a power
failure, the C9900-P224 power supply unit is equipped with a UPS output
for connecting a Control Panel. The maximum load for the output is 1.4 A.

The UPS output is located on the power supply unit adjacent to the mains
plug (see also section Product Description.

UPS output function

 The 27 V DC connection at the UPS output is live even after a power

failure. The maximum load is 1.4 A (C9900-P224 only).

 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.
