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
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-240 REDs is an electrical cabinet housing two 24 Vdc power supplies which
operate in parallel to provide Redundant power to a varying number of reading devices
(depending on the product), along with their relative accessory devices. It is specifically
designed for use in Baggage Handling Reading Stations. See chapter 4 for details.
As shown in the Electrical Diagram in Appendix A, the AC Input Line passes through two
sets of protective thermo-magnetic circuit breakers and connects to the two mono-
phase switching power supplies.
The 24 Vdc outputs are connected through a Decoupling Module and then routed
through a protective current limiting Miniature circuit breaker (MCB), 10 A, 1p, C-Char
before arriving at the output terminal blocks.
Two output power supply status monitoring signals (DC-OK) for each power supply 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.
The major advantage to the PWR-240 REDs redundant power supply is that if a single
power supply fails, it can be replaced by qualified personnel without shutting down the
system, (hot-swap).
OUTPUT PROTECTION
The two 24 Vdc 10 A nominal supplies operate in parallel. Output short-circuit and over-
load protection is mainly provided through the current limiting MCB.

OPERATING FEATURES
2 PWR-240 REDS
Short-Circuit Protection
If a short-circuit occurs on the output lines (electrical event), the MCB opens within less
than 1 second (t) interrupting supplied power. Refer to the diagram below.
Figure 3 – Short-Circuit Protection
The short-circuit must be resolved and the MCB must be manually re-armed to restore
normal operation.
Overload Protection
Overload is a condition in which, due to a malfunction, current above the nominal max
value is required to maintain output device functioning. This condition can be sustained
for short periods but causes a thermal event which over time could ultimately damage
wiring and/or devices.
Since the PWR-240 REDs utilizes two 24 Vdc 10 A power supplies in parallel, they divide
the required current evenly and so can provide up to a combined 20 A without going
into an overload condition.
Overload protection is instead provided by the 10 A MCB as described in the figure
below.

INSTALLATION MANUAL 3
After time (t) in seconds, the MCB opens, interrupting supplied power according to the
following table:
The overload condition must be resolved and the MCB must be manually re-armed to
restore normal operation.

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 6.
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 10
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 7 and "AS-I Cable Insertion"
on page 8.
24 Vdc Industrial Ethernet Switch
Mount the Industrial Ethernet Switch inside the cabinet and connect the 24 Vdc
wires to power it as described in "Installing Accessory Industrial Ethernet Switch" on
page 12. All Ethernet Cables must pass through the grommets of the Cable Entry
plate.
Optional 12 Vdc Power Block for RFID Applications
Mount the 12 Vdc Power Block inside the cabinet, prepare the AC cord and con-
nect it to the AC input terminals as described in "12 Vdc Power Block Installation
(Optional)" on page 14.
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.
