Note: Displays with a 2-position term panel (refer to Layout Drawings in
Appendix A ) are equipped with supplemental protection devices that carry a
UL1077 (IEC 60947, VDE 660) rating. These devices are only intended to protect
the components within the display. Suitable devices must be used for the equipment
and feeders supplying power to the display.
3. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code.
4. Display power will terminate directly to the power panel within the display.
Some of the monochrome displays will have a J-box for termination of
power.
5. Connect the grounding electrode conductor, at the grounding lug, to the
display at this time.
6. You may also route the signal cable and connect the grounding electrode
conductor to the signal termination enclosure (when required) at this time.
7. Signal into the enclosures must be routed through conduit. The size of the
knockouts in the enclosures requires the use of 3/4" conduit.
8. The quick connect cable from the enclosure to the display can be routed
through conduit or the display pole.
