Original instructions
5.1.1 Pin assignments of the I/O modules
5.2 System connector assembly
The system plug has holes on the top and rear. Suitable cable glands for
these holes are included with the device.
• One cable gland with M20 cable fitting
• Two blanking plugs for the unused outlets
Note: You can also purchase the SafeZone multizone safety laser scanner
with pre-assembled system connectors (see Section 5.3 “Pre-assembled
system connector” on page 33 and Section 12 “Ordering information” on
page 52).

ATTENTION The length of the spare cable should be such
that the system plug cannot inadvertently be
plugged into a neighboring SafeZone safety
laser scanner.
From experience 20 to 30 cm spare cable at the
scanner have proven to adequate. In this way
you avoid the inadvertent connection of the
system connector to an adjacent SafeZone
safety laser scanner and operation of a SafeZone
safety laser scanner with an incorrect
configuration. The spare cable enables you to
easily change out the SafeZone safety laser
scanner.
