SAFETY REGULATIONS
INSTALLATION MANUAL v
SAFETY REGULATIONS
Electrical Safety
This product conforms to the applicable requirements contained in the following Euro-
pean Standards:
• EN 61439-1
• EN 60204-1
• EN 60950-1 +A11 +A1 +A12 +A2
•EN62368-1
Product Data Label
The Product data label is located on the outside door panel.

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 assess-
ment 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 inter-
ference in which case the user may be required to take adequate measures.

CHAPTER 1
OPERATING FEATURES
DESCRIPTION
The PWR-240B 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 through a direct
connection block. The direct connection block is 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.
OUTPUT PROTECTION
This power supply is specifically designed to power Datalogic devices and implements
output protection according to the type of overload behavior.
Light Overload
Light Overload is defined as application of a load that results in a reduction of the out-
put voltage that remains above 13V. In this case the power supply can deliver up to 14
amperes continuously, see Figure 3 Overload Behavior. Datalogic devices by their nature

OPERATING FEATURES
2 PWR-240B
cannot cause overload conditions since they are equipped with intrinsic power monitor-
ing systems. The AIR CLEANING SYSTEM fans also have this function.
Figure 3 - Overload Behavior
Heavy Overload (including short-circuit)
Heavy Overload is defined as application of a load which causes a reduction in voltage
below 13V. This causes the power supply to enter HICCUP operation where power is
supplied for 2 seconds and then shuts off for 18 seconds. This procedure is repeated
until the short-circuit or overload is resolved, see Figure 4 Short-Circuit Protection HIC-
CUP Mode. For this condition, the maximum length of the power cables between the
power supply and the powered devices guarantees the behavior of a short-circuit down-
stream of this cable.
Figure 4 – Short-Circuit Protection HICCUP Mode

CHAPTER 2
PRE-INSTALLATION CHECKLIST
This chapter can be used as a checklist to verify all the steps necessary to complete
installation of the PWR power supply.
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 bolts provided in the
package. See "Cabinet Mounting" on page 5.
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 instruc-
tions for backbone and branch wiring. See "Laser Barcode Scanners" on page 8 and
your scanner manual for details.
All cables must pass through the cable entry plate using the correct AS-I cable
grommets as described in "Cable Entry Plate" on page 6 and "AS-I Cable Insertion"
on page 7.
HIGH VOLTAGE: 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.

PRE-INSTALLATION CHECKLIST
4 PWR-240B
SYSTEM WIRING: AC INPUT
4. To comply with EN 60950-1:2007 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 EN 60950-1:2007 par. 3.2.3; the AC input cable must have a maxi-
mum 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
"AC Line Input Voltage" on page 12.
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-240B installation is now complete.
