Figure 17: Making Cage Clamp Connections
The following steps will need to be done to complete internal connections:
1. Open the display as explained in Section 4.4 and locate the power
termination panel for these displays.
2. Route the cable through conduit to the back of the display. Use the 3/4"
knockout for access, being careful not to damage any internal components.
3. Disconnect the wires to the terminal block and connect the wires from the
direct cable.
4. Using a small flat screwdriver to open the cage clamps, release the jumper
wires connected to the external wires going to the external power
termination box.
5. Install the wires from the direct circuit into the cage clamps following the
directions in Figure 17.
6.
Make the following connections as shown in Figure 18.
• Hot to main lug labeled “Line 1”
• Hot to “Line 2”
• Neutral to Neutral bus bar
• Ground to Ground bar
7. Power will need to be connected to all display faces
Note: The 4, 6 and 8 circuit displays do not use cage clamps. Feeders from the main
disconnect must be connected to the main lugs of the power termination panel.
