Main Disconnect
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 be completely disconnected. Use a 3-conductor
disconnect so that both hot lines and the neutral can all be disconnected. The main
disconnect should be mounted at or near the point of power supply connection to the
display. A main disconnect is to be provided for each supply circuit to the display.
The disconnecting means must be located in a direct line of sight from the display or
outline lighting that it controls. This requirement provides protection by enabling a
worker to keep the disconnecting means within view while working on the display.
Exception: Disconnecting means that are capable of being locked in the open
position may be located elsewhere.
3.7 Signal Termination from Computer to Display
The AF-3160 is designed for quicker connection to other displays and other
additional equipment. Connection of the first display to the control equipment needs
to be wired to the controller, modem, fiberboard, or surge suppression card in that
display. Depending on the display type ordered the following cables may be
provided with the display:
