2. Remove the bottom left two modules (AX01

and AX02) to expose the power enclosure

and signal panel. To do this, use a

" Allen

wrench to turn the latch access fasteners one-

quarter turn. Turn the top latch clockwise and

the bottom latch counter-clockwise. Lift each

module away from the display; reach behind

it and disconnect all power and signal

connections. Refer to Figure 17

3. Locate the controller and power termination

box for these displays in the Component

Layout Diagram for your sign

4. The controller receives the incoming signal

and relays it to the individual modules

5. Route power to the display through a fused

disconnect switch capable of opening all ungrounded power conductors.

Install this disconnect within the line of sight of any personnel performing

maintenance on the display. If the disconnect is located out of sight of the

display, it must be capable of being locked in the open position

Figure 17: Removing a Module

6. Power conductors from the disconnect to the display should be routed

through conduit in agreement with local code

7. You may route the signal cable from the control computer to the display at

this time – Be sure to run the power and signal cables in separate

conduit
