2.4.2 Power Wiring
Reference Drawings: Connector Plate, CH-1436H ............. Drawing A-63501
Power&Signal Entrance,CH-1436 .... Drawing A-63923
The CH-1436H display requires a 120/240 VAC, 40 amp circuit per line. When
equipped with 30W, 30R20 reflector lamps, the maximum current draw is 54 amps.
Route power wires into the display and connect to TB41 in the entrance enclosure as
shown in Drawing A-63923.
Connect the ground wire to E41 and to a ground rod near the display according to
local codes and Section 2.5.
2.5 Grounding
Displays MUST be grounded according to the provisions outlined in Article 250 of the
National Electrical Code.
The display must be connected to earth-ground. Proper grounding is necessary for reliable
equipment operation. It also protects the equipment from damaging electrical disturbances
and lightning. The display must be grounded as follows or the warranty will be void.
The support structure of the display cannot be used as grounding. The support is generally
embedded in concrete, and if in earth, the steel is either primed or it corrodes, making it a poor
ground. Use one ground rod at each display support column.
The National Electrical Code requires the use of a lockable power disconnect near the display.
Provide a lockable disconnect switch (knife switch) at the display location so that all power
lines can b completely disconnected. Use a 3-conductor disconnect so that both hot lines and
the neutral can all be disconnected.
There are two considerations for power installation: New Power Installation and Existing
Power Installation. These two power installations differ slightly, as described in the following
sections.
