After locating the power termination panel and display controller on the shop drawing, complete the
following steps to ready the display for power and signal hook-up.
1. Remove the necessary lens/reflector assemblies to gain access to the termination panel and display
controller. Lens/reflector removal is addressed in Lens/Reflector Assemblies in Section 4.3.
Venus 1500 systems need only access the fan control enclosure if installing two displays together
in a 2V cabinet configuration. Venus 4600 systems do not need access to the fan control enclosure
regardless of cabinet configuration.
2. Remove the covers from the power termination panel, the display controller and, if needed, the fan
control enclosure.
Daktronics completes all internal power and signal wire routing and connecting prior to shipment.

Only qualified individuals should perform power routing and termination to the display. It is
the responsibility of the installer to ensure the installation will adequately meet local codes and
standards.
! Run power from the power distribution point to the termination panel of each display face.
! Run power separately to each display face.
! This power is run through conduit according to national and local electrical codes.
! Use the knockouts in the back sheet located near the termination panel for the conduit entrance
point. This area is marked with a label (“Recommended Pwr & Sig Entrance Location”).
! Power cannot route through the display. Do not use the support conduit, located inside the
display, for power routing.
