INSTALLATION MANUAL 1
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

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.

CONNECTIONS
DC LOW VOLTAGE CABLE INSERTION
The Cable Entry Plate has several sealing grommets that must be inserted to provide
IP65 protection capability. This includes AS-I cable sealing grommets.
Cable Entry Plate
Follow these instructions to correctly insert the cables:
1. Determine the number and size of the cables coming into and leaving the PWR-
240B.
2. Unmount the Cable Entry Plate and select all the necessary grommets for your
application.
3. Insert the correct size sealing grommets and positions relative to these cables.
Unused positions must mount the closed grommets with their flat closed surface
facing the outside of the PWR.
4. Remount the Cable Entry Plate.
5. Press the cable end through the proper grommet so that it seals around the cable.
The Cable Entry Plate has 10 cable entry points with the following grommet kit supplied:

DC OK Monitoring
The DC voltage terminal block provides two wiring terminals (13-14), which monitor the
status of the switching power supply (DC OK feature). When the power supply module
runs correctly, lines 13 and 14 form a normally closed contact. If the power module
experiences problems (i.e. output overload causing output voltage to be reduced by less
than 90% of nominal) these lines open. Lines 13 and 14 are decoupled from the power
output lines and can be connected to a free digital input to signal this alarm condition.
DC Direct Output
The 24 volt DC Output terminals are direct. Connect the output devices according to
your application requirements.
LASER BARCODE SCANNERS
Supply Capacity When Wiring Directly to AS-I Compatible Scanners
For direct wiring, power distribution is performed simultaneously for all the scanners.
However all the scanner motors start up slowly so that there is no significant peak cur-
rent draw. See the specific scanner manual for consumption data.
The maximum number of same type scanners to be supplied for direct wiring the PWR-
240B is shown in the table below and depends on the wiring topology:
The following products are also AS-I compatible: DS5100, DM3610, SC5000. In case of
networks using a mix of products, you must calculate the total power consumption so as
not to exceed the limits for the specific topology used. See the specific product refer-
ence manual in the Technical Features chapter for consumption data.
The power supply unit is connected directly to the scanners via AS-I cabling.

AC LINE INPUT VOLTAGE
Wire according to the following points:
• Primary wiring: Overcurrent protection should be provided by a 16 A building
installation circuit breaker. PWR-240B input components are rated for an Icp of 10
kA max.
• Wiring methods from the branch circuit breaker to the PWR-240B power supply
shall comply with the National Electric Code ANSI\NFPA. The Datalogic DWS-
SWITCH is an AC Power Disconnector and Distributor cabinet which provides this
protection.
• For primary wiring use a 3-conductor cable (between 2.5 mm2 - 4 mm2 (13 AWG –
11 AWG), for every conductor. Choose the overall cable diameter and UL Listed
conduits accordingly. The AC input cable must be inserted through the AC Input
Cable Compression Connector.
• The individual conductors must be inserted into the dedicated terminal blocks on
the DIN rail (see figure below) which are marked Line (L) neutral (N) and Protec-
tion Earth (PE).
• Replace the protection cover over the spring clamp connector after correctly
installing the wires.
