Connecting the 24 VDC power supply
Note before connecting the device
WARNING
Safety extra-low voltage (SELV)
The device should 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 60950-1. A
protective conductor must also be used. The conductors must withstand the short-circuit
current of the 24 V DC power source, so that a short-circuit will not damage the cable. Only
connect cables with a minimum cross-section of 1.3 mm
2
(AWG16) and a maximum cross-
section of 3.3 mm
2
(AWG12).
Note
The 24 V DC power source must be adapted to the input data of the device (see
specifications).
