GUIDE TO INSTALLATION
The following can be used as a checklist to verify all the steps necessary to complete
installation of the PWR power Supply.
CAUTION
Before wiring the device make sure the power is disconnected to avoid
electrical shock.
1) Read all information in the section “Safety Precautions” at the beginning of this manual.
2) Mount the PWR near the Reading Station.
3) With AC line voltage OFF, wire the AC Line input to the PWR AC Terminal Block see
par. 1.2.1.
4) System Wiring:
Directly to Scanners
Provide correct and complete system cabling to the PWR according to the signals
necessary for the layout of your application. (See par. 1.2.2 and your scanner manual
for details. All system cables must pass through the glands.
With SC8000
Connect the SC8000 Controller to the PWR by means of the appropriate cables (see
par. 1.2.3 and the SC8000 manual for details). All cables must pass through the glands.
5) Close and lock the PWR enclosure.
6) Apply the AC line voltage from the building installation and check that the PWR powers
up correctly.
The installation is now complete.

1.2 ELECTRICAL CONNECTIONS
The PWR-240/PWR-480 power unit provides a terminal block through which AC Line voltage
enters and 24 Vdc Low Voltage output is provided.
The terminal block also allows various system wiring terminals so that all system wiring (i.e.
host communication, P.S., Encoder, etc.) can be provided through a single cable when
connecting directly to the scanners.
For connection to the SC8000 Controller, only the 24 V DC low voltage output is necessary.

1.2.1 Input Line Voltage
Wire according to the following points:
Primary wiring: Overcurrent protection should be provided by a 12 to 15 A building
installation circuit breaker. Wiring methods from the branch circuit breaker to the PWR-240/
PWR-480 power supply shall comply with the National Electric Code ANSI\NFPA.
For primary wiring use a 3-conductor cable with minimum size 13 AWG for every conductor.
Choose the overall cable diameter and UL Listed conduits accordingly. These conductors
have to be inserted into the dedicated terminal blocks on the DIN rail (see diagram) which
are marked Line (L) neutral (N) and Protection Earth (PE).
The terminal block marked with the ground symbol is a special block which allows direct
connection of the Protection Earth with the enclosure of the PWR-240/PWR-480.
The AC input cable must be inserted through one of the Glands and the individual wires
installed into the AC terminal block.
Replace the protection cover over the spring clamp connector after correctly installing the
wires.
The AC plug can only be used temporarily during installation or maintenance procedures.

1.2.2 Supply Capacity When Wiring Directly to Scanners
A general rule to consider is that each scanner requires both peak power and steady state
power.
For direct wiring, power distribution is performed simultaneously for all the scanners. This
means that the PWR must bear the peak power draw of all the scanner motors starting up
together. See the specific scanner manual for consumption data.
PWR-240:
The maximum peak power propagated is 24 V x 15 A = 360 W, while the steady state
(normal) power is 24 V x 10 A = 240 W.
PWR-480:
The maximum peak power propagated is 24 V x 26 A = 624 W, while the steady state
(normal) power is 24 V x 20 A = 480 W.
Due to these limits, the maximum number of scanners to be supplied for direct wiring is:
