Note the sensor's maximum permissible tightening torque of 2 Nm.
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).
■
The sensor is a device of protection class III.
■
Only operate the device with an LPS (limited power source) in accordance with
■
IEC 62368-1 or an NEC Class 2 power supply unit.
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 observed 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 properly 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.
Operation in short-circuit protected network at max. 8 A.
