Power is terminated internally to the power termination board in all displays except the 8-
pixel high displays. Included in this section are the instructions for both 120 VAC and 240
VAC power sources, including:
• terminating single-phase power
• terminating three-phase power
• terminating power to the J-box (single-phase, 8-pixel high displays only).
Schematic Drawing B-277048 may also be referenced, if necessary.
Terminating single-phase power to the internal power termination panel:
1. Open the display as explained in Section 6.1 and locate the power termination panel.
2. Route the cable through conduit to the back of the display. Use one of the knockouts
for access, being careful not to damage internal components.
3. For 120/240 (3 wire + ground), connect the neutral wire to the neutral lug and the
live wires to Line 1 and Line 2. Refer to Figure 14.
For 240 VAC, (2 wires + ground), connect the neutral wire to the neutral lug and the
live wire to Line 1 lug. Refer to Figure 15.
4. The ground wire connects to the grounding bus bar.
