CE COMPLIANCE
CE marking states the compliance of the product with essential requirements listed in the
applicable European directive. Since the directives and applicable standards are subject to
continuous updates, and since Datalogic promptly adopts these updates, therefore the EU
declaration of conformity is a living document. The EU declaration of conformity is available
for competent authorities and customers through Datalogic commercial reference contacts.
Since April 20th, 2016 the main European directives applicable to Datalogic products require
inclusion of an adequate analysis and assessment of the risk(s). This evaluation was carried
out in relation to the applicable points of the standards listed in the Declaration of Conformity.
Datalogic products are mainly designed for integration purposes into more complex systems.
For this reason it is under the responsibility of the system integrator to do a new risk
assessment regarding the final installation.
Warning
This is a Class A product. In a domestic environment this product may cause radio interference
in which case the user may be required to take adequate measures.

1 OPERATING FEATURES
1.1 DESCRIPTION
The PWR-120 is an electrical cabinet housing a 24 Vdc power supply which is used to power
up a varying number of reading devices (depending on the product), along with their relative
accessory devices. See chapter 4 for details.
As shown in the Electrical Diagram in Appendix A, the AC Input Line passes through a
protective thermo-magnetic circuit breaker and connects to the monophase switching power
supply.
The 24 Vdc output power is connected to the output terminal blocks which are protected by
the internal power supply features.
Two output power supply status monitoring signals (DC-OK) are provided to connect to an
optional digital alarm. If for some reason the output voltage is reduced by less than 90% of
nominal) these lines open.
1.2 OUTPUT PROTECTION
The power supply implements an overload protection.
1.2.1 Overload Protection
In the event of sustained output current overloading, overload protection is provided where
overload power is supplied as explained in the examples below:
Example 1: Up to 120% power overload
The overload is supplied for approximately 12 seconds and then is reduced (Voltage and
Current) to about 104% power continuously. In this case output voltage is reduced but remains
above 20 Vdc.
Figure 3 –Overload Protection up to 120%

Example 2: 125% power overload
The overload is supplied for approximately 10 seconds and then is reduced (Voltage and
Current) to about 95% power for another 10 seconds. In this case the output voltage falls below
20 Vdc and therefore the power supply shuts down for a recovery time of 17 seconds. This
procedure is repeated until the excessive current overload is resolved.
Figure 4 –Overload Protection at 125%
Example 3: 150% power overload
The overload is supplied for approximately 4 seconds and then is reduced (Voltage and
Current) to about 48% power for another 2 seconds. In this case the output voltage falls below
20 Vdc and therefore the power supply shuts down for a recovery time of 17 seconds. This
procedure is repeated until the excessive current overload is resolved.

2 PRE-INSTALLATION CHECKLIST
This chapter can be usedas a checklist to verify all the steps necessary to complete installation
of the PWR power Supply.
CAUTION: Opening the cabinet requires a key that should be used by a
person adequately advised or supervised by an electrically skilled person
to enable him or her to perceive risks and avoid hazards which electricity
can create. Internal components guarantee an IP20 degree of protection
against direct contact.
1) Read all information in this manual before installation, paying particular attention to all
Caution and Warning notes.
2) Mount the PWR to the Station frame using the brackets and boltsprovided in the package.
See par. 3.1.
SYSTEM WIRING: DC OUTPUT
3) Connect your devices to the PWR according to your application.
Barcode Scanners
Correctly connect the AS-I cabling to the PWR using the AS-I cable wiring instructions for
backbone and branch wiring. See par. 4.3.1 and your scanner manual fordetails. All cables
must pass through the compression connector as described in par. 4.1.
Image Based ID Readers
Connect your specific product as described in the sub-paragraph under 4.4 and the reader
manual. All cables must pass through the compression connector as described in par. 4.1.
SYSTEM WIRING: AC INPUT
4) To comply with EN60950-1:2007 par.1.7.2.2, par. 2.7.1, par 2.7.4, par. 3.4.6, and to
protect the AC input connection to the device; a disconnecting device with built in
overcurrent and earth protection shall be installed external to the equipment according to
local regulations.
According to EN60950-1:2007 par. 3.2.3; the AC input cable must have a maximum
diameter of 14mm and the conduit a max diameter of 16mm.
5) With AC line voltage OFF, wire the AC Line to the AC Line Input Terminal Block see par.
5.1.

SYSTEM WIRING: TEST
6) Apply the AC line voltage from the building installation or the DWS-SWITCH and check
that the PWR powers up correctly. The green DC-OK light should be on steady and the
overload light (red) should off.
7) Close and lock the PWR enclosure and check that it does not open (lock functions
correctly).
The PWR-120 installation is now complete.
