14 DCX 250 Installation Guide
Powering Up/Adjusting the Controller
Both the DCX 250 inside the Infinity CX 9000 and the DCX 250 in its
own cabinet have a battery you need to connect.
Connecting the Battery
Lift off the front display panel on the DCX 250. Inside, on the back of
the display screen, find the AA battery on the upper left of the board.
Figure 8 shows the location of the battery. Remove the plastic tab
below the clip on the battery to activate the battery.
The battery is a 850 mA-hr 3.6 V primary lithium battery that maintains
RAM when AC power goes out.
Powering Up
The DCX 250 inside the Infinity CX 9000 runs off the power supply of
the Infinity CX and begins operating when you connect AC power to the
Infinity CX 9000.
For the DCX 250 in its own cabinet, you must check to be sure the fol-
lowing are correct:
1. Be sure the AC power is wired properly. Check to be sure all three
wires have been connected.
2. Be sure the controller has a true earth ground.
3. Be sure you have used the proper cables and correct lengths.
4. Be sure the battery is connected.
If you have completed all appropriate sections in this manual and in-
stalled all Infinet controllers, you are now ready to power up the
controller.
