Electrical Installation
Electrical hookup for both 120 V and 230 V indoor scoreboards consist of a simple,
seven-step process. Begin by opening the left access panel of the module
(Refer to
Drawing A-130661
):
1.
Mount the power/signal plate in the left side of the lowest digit module in
the display. Remove both the 2" knockout and the upper 7/8" knockout from
the left end of the module. Run the power cord out of the module through
the knockout and position the plate inside, on the end. Secure the plate with
two screws, inserting them externally through the pre-drilled holes.
2.
Route the cable from the power/signal plate into the driver enclosure and
connect the 12-pin plug to the mating plug.
Note
: All the connectors are “keyed”— they can only fit into the jacks one
way.
3.
Insert 2'' bushings into the holes between modules.
4.
Pull the power/signal cable from the lower module through the 2" hole in
the top of the cabinet up into the next module and connect the 12-pin plug to
the mating connector in the driver enclosure.
5.
Repeat the connection process in Step 4 with any other modules in the
system.
6.
Connect the power cord to a 120 V AC power outlet, and connect signal to
the
1
/
4
" phone jack in the end of the bottom module.
7.
Replace cover and panels. Insert a 2" hole plug in the bottom hole of the
lowest module.
The hookup procedure for a 230 V display is identical; the only difference
between the two electrical systems is the 230 V power cord
(Refer to
Drawing
A-130676
).
3.3 Internal Cable Routing
Reference Drawing:
Internal Cable Routing ...........................................
Drawing A-130679
Section 3.1
describes signal and power connections for scoreboard digit modules
arranged vertically. Horizontal, or side-by-side, modules additionally require
installation of a power/signal interconnect cable. Only one interconnect cable is
needed for each installation
(Refer to
Drawing A-130679
).
Connect the modules by running the interconnect cable from the driver of the bottom
left module to the driver of the bottom right module. There are knockouts in the ends
of the modules through which the cable may be run. The cable is connected with
mating 12-pin plugs in each module.
