CAUTION
Safety notices!
Ä
The bar code reader is completely sealed and must not be opened.
Ä
Do not try to open the device under any circumstances, as this avoids both degree of pro-
tection IP 54 and the warranty.
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 (SELV).
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 LPS/Class 2 circuits in accordance with the NEC
(National 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 ISO 13849-2, Table D.4.
• Connection cable with Sub-D connector, 15-pin
• Connection cable with M12 connector, 12-pin
NOTICE
