NOTE
To be able to unambiguously differentiate between the host device and the guest
device in an EFI system, one safety laser scanner must be configured as the guest.
b
To define the guest device, wire a jumper between terminals 7 (ERR) and 10 (A1).
The jumper always defines the guest device. This jumper must not be fitted on the host
device.

Unassembled system plug
Important information
NOTE
Experience has shown that 20 to 30 cm of cable reserve on the safety laser scanner is
ideal. This prevents the system plug from accidentally being plugged into an adjacent
safety laser scanner and putting a safety laser scanner with an incorrect configuration
into operation. You can easily exchange the safety laser scanner with the cable reserve
if needed.
b
Keep the cable reserve short enough that the system plug cannot accidentally be
plugged into an adjacent safety laser scanner.
NOTE
You can also purchase the safety laser scanner with pre-assembled system plugs with
various lengths of cable.
System plug
The system plug has holes on the top and rear. Suitable cable entries for these holes
are included with the device. The number of cable entries differs depending on the vari‐
ant.
SX0A-A0000B system plug:
•
1 cable entry without M12 cable gland (blind plug)
•
1 cable entry with M20 cable gland
•
2 blind plugs for the second exit side
