Mounting and wiring
Connections:
X940 power connection:
OUT:
• Earth
• 0V
• +24V
A control panel or a monitor can be connected here. The Port supplies external devices with max. 48 W. Use
a corresponding fuse to secure the connected devices.
SIG:
• 0V
• FAIL
FAIL is set to "1" in the event of a power failure. Technically the output is set to 24 V. 0 V is the reference
potential for this. It can be wired, for example, to the digital channel of an input terminal and thus additionally
evaluated.
BAT:
• Earth
• -BAT
• +BAT
The Smart Battery is connected here. Earth, -BAT and +BAT are fed accordingly to the connections on the
battery pack. The battery is charged or, in the case of a power failure, the CX system is supplied with power
via these cables.
X941 Battery:
The control cable is connected to the Smart Battery via this connection. An RJ45 patch cable (CAT6) is used
for the connection. The upper LED (LINK) lights up when the battery and the power supply unit are
connected. The lower LED lights up when the battery is being charged.
Note
Confusion with the network connection
A serial protocol is processed via this port for communication between the power supply
unit and the Smart Battery. Exclusively the Smart Battery may be connected here!
