Please note the following:
Electric shock and risk of fire
Voltages that exceed an extra-low voltage can cause electric shock or fire. Death or serious bodily injury can result.
• The device may only be connected to a 24 V DC power supply which meets the requirements of a safe extra-low voltage
(SELV/PELV) in accordance with the standard IEC/EN/DIN EN/UL 61010-2-201.
-low voltage (SELV)
The device may only be connected to a 24 V DC power supply which meets the requirements of safe extra-low voltage
(SELV) according to IEC/EN/DIN EN/UL 61010-2-201. A protective conductor must also be used.
The cable cross-section must withstand the short-circuit current of the 24 V DC current source so that a short-circuit will
not damage the cable.
• Only connect cables with a cross-section of ≥ 0.5 mm².
Requirements
• The device is installed.
• The protective conductor is connected.
• The connection terminal is wired.
