Connecting the 24 V DC power supply
To be noted before you connect the device
Note the following in order to operate the device safely and according to regulation:
The device should only be connected to a 24 VDC power supply which satisfies the
requirements of safe extra low voltage (SELV).
If the device is used on a wall, in an open rack or other similar locations, an NEC Class 2
current source is required in order to meet the UL requirements (UL 60950-1). In all other
cases (IEC / EN / DIN EN 60950-1) either a current source of limited output (LPS = Low
Power Source), or a line-side fuse or a line-side circuit breaker is necessary. The power
needs to be limited to a value below 4.16 A. The fuse value required: Max. 4 A.
Use the special plug supplied to connect the supply voltage. Connect the protective
conductor (see Chapter PE terminal (Page 97)).
NOTICE
The permitted cable cross-section for the 24 VDC connection is 0.75 mm
NOTICE
If a CompactFlash card is used in the device, make sure that the card is seated correctly
before you connect it.
