Connecting the (24 V) DC power supply
Note before connecting the device
WARNING
Only connect the device to 24 V DC power supply systems which meet the requirements of
a safe extra-low voltage (SELV); in addition, a protective conductor must be connected.
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).
NOTICE
The 24 V DC power source must be adapted to the input data of the device (see
specifications).
