Electrical connection
CAUTION
Safety notices!
Ä
The bar code reader is completely sealed and must not be opened.
Ä
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
Ä
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
Ä
The power supply unit for the generation of the supply voltage for the bar code reader and
the corresponding connection units must have a secure electrical insulation according to
IEC 60742 (PELV).
Ä
If faults cannot be rectified, take the device out of operation and protect it from accidentally
being started.
CAUTION
UL applications!
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC (Na-
tional Electric Code).
NOTICE
Laying cables!
Ä
Lay all connection cables and signal lines within the electrical installation space or perma-
nently in cable ducts.
Ä
Lay the cables and lines so that they are protected against external damages.
Ä
For further information: see EN ISO 13849-2, Table D.4.
• 6-wire connection cable with open cable end
• Pigtail with M12 connector, 8-pin
The bar code reader is provided with the following interfaces:
• Voltage supply
• 1 switching input
• 1 switching output
• Process and service interface RS 232

5.1
Operating voltage
The bar code reader is designed for an operating voltage of 5 V. The operating voltage is fed in via the con-
nection cable (see chapter 5.3 "Pin assignment").
• +5 VDC: pin 1 of the 8-pin M12 connector plug or red wire of the connection cable with open cable end
• GND: pin 3 of the 8-pin M12 connector plug or violet wire of the connection cable with open cable end
5.2
Housing ground
To avoid electromagnetic interference, a low-impedance connection is necessary from the housing to the
machine ground.
