Subject to change without notice
NOTICE
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
Only operate the device with safety/protective extra-low voltage (SELV/PELV).
■
Only operate the device with an LPS (limited power source) in accordance with IEC
■
60950-1 or an NEC Class 2 power supply unit.
UL: Enclosure Type 1
■
The sensor is a device of protection class III.
■
NOTICE
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
Only carry out wiring work when the power is off.
■
Only connect and disconnect electrical connections when the power is off.
■
The electrical installation must only be performed by electrically qualified person‐
■
nel.
Standard safety requirements must be met when working on electrical systems.
■
Only switch on the supply voltage for the device when the connection tasks have
■
been completed and the wiring has been thoroughly checked.
When using extension cables with open ends, ensure that bare wire ends do not
■
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
Wire cross-sections in the supply cable from the user's power system must be
■
selected in accordance with the applicable standards.
Only operate the device with an LPS (limited power source) in accordance with IEC
■
60950-1 or an NEC Class 2 power supply unit.
All circuits connected to the device must be designed as SELV/PELV circuits.
■
Operation in short-circuit protected network at max. 8 A.
■
NOTE
Layout of data cables
Use shielded data cables with twisted-pair wires.
■
Implement the shielding design correctly and completely.
■
To avoid interference, e.g., from switching power supplies, motors, clocked drives,
■
and contactors, always use cables and layouts that are suitable for EMC.
Do not lay cables over long distances in parallel with voltage supply cables and
■
motor cables in cable channels.
The IP enclosure rating for the device is only achieved under the following conditions:
The cables plugged into the connections are screwed tight.
■
Any electrical connections that are not being used must be fitted with protective
■
caps that are screwed tight (as in the delivery condition).
Any other lids present must be closed and lie flush on the device.
■
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!
