360 Switch/CLB Panel Backlight Installation:
The backlight board is designed to snap into place behind the label windows.
Removal of the front bezel is not necessary.
1. Orient the backlight board so the LEDs face the label windows and the “+12” text is upright.
2. From the back of the panel, position the right edge of the board between the plastic tabs under the CLBs.
3. Press against the right edge of the board until the right edge snaps into place.
4. Press down on the left side of the board until the left edge snaps into place.
5. Repeat for each switch/CLB module.
6. If using a 12VDC power source, connect all “+12” quick-connect tabs to 12VDC positive (+).
If using a 24VDC power source, connect all “+24” quick-connect tabs to 24VDC positive (+).
7. Connect all “-NEG” quick-connect tabs to DC negative (-).
