Notes on the electrical installation
NOTICE
Device damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the device.
■
Only operate the device with safety/protective extra-low voltage (SELV/PELV).
■
The sensor is a device of protection class III.
NOTICE
Device damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the device.
•
Only operate the device with an LPS (limited power source) in accordance with IEC
60950-1 or an NEC Class 2 power supply unit.
NOTICE
Device 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.
The IP enclosure rating for the device is only achieved under the following conditions:
■
The cables plugged into the connections are screwed tight.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!
