Connecting the power supply
The power supply is connected to the X1 terminal strip and must always be via a
time-lag 1 A fuse. The device does not have a separate power switch.
Figure 6-1 Connecting the power supply
Note before connecting
Functional check
After switching on, the POWER LED must show a green light.
Warning
Only connect the device to 24 VDC power supplies that meet the requirements of
a functional extra-low voltage with safe isolation (PELV); in addition, a protective
conductor must also be connected. The cable cross-section must be matched to
the short-circuit current of the 24 VDC power supply, so that with a short-circuit,
damage is not caused by the cable. Only connect cables with a cross-section of
minimum 0.25 mm
2
(AWG23) to maximum 2.50 mm
2
(AWG13).
Notice
The 24 VDC power supply must be adapted to the input data of the device, see
Technical Data
(Section 13).
Caution
Ensure that the functional ground is connected correctly.
Make sure the polarity is correct for DC voltage.
