SICK Lector85x Operating Instructions

•
To avoid interference, always use EMC-compliant cables and layouts. This applies,
for example, to cables for switched-mode power supplies, motors, clocked drives,
and contactors.
•
Do not lay cables over long distances in parallel with voltage supply cables and
motor cables in cable ducts.
Voltage supply
•
Configure the circuits connected to the device as ES1 circuits or as SELV circuits
(SELV = Safety Extra Low Voltage). The voltage source meets the requirements of
ES1 (EN62368-1) or SELV (EN60950-1).
•
The device must be supplied with an energy-limited source as per UL61010-1, 3rd
ed. cl. 9.4 or a limited current source as per UL62368-1 or Class 2 as per NEC.
•
Required power output of the voltage source: at least 48W
•
For a supply voltage of DC 24V ±20%, protect the cables with a separate fuse.
The type of fuse required depends on the cable used (typically e.g. cable M12
17-pin with 2A fuse, cable M12 5-pin with 4A fuse). Install the fuse in the supply
circuit at the start of the supply cable.
•
To ensure protection against short-circuits/overload in the customer’s supply
cables, choose and implement wire cross-sections in accordance with the appli‐
cable standards.
