3.2.1 Power supply
The power supply for the ZK-MasterIV (HW V 1.4) is connected to the Datafox device power supply unit
12 V 3 A DC via the 8 pole strip terminal, position (
4
) in figure
. From HW V 2.0 on the terminal is
supplied with power (24 V 300 mA power supply unit) via the Molex connector (
8
) in figure
Caution:
In principle, only one voltage source may be connected to the ZK-MasterIV. Only
a 12 V/3 A DC voltage source may be connected to the ZK-MasterIV with HW
V 1.4. The terminal and the entire access control-net (16 modules at most) can
be energized by this voltage source. You have to connect a 24 V/300 mA AC/DC
power supply unit to the ZK-MasterIV from HW V 2.0 on. By this power supply
unit one external reader at most may be powered via the RS285 B interface. Please
note the information in figure
