Electrical Installation
3-7
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-3300 is designed for quicker signal and power connection to the display and
between displays.
•
Signal will terminate to a watertight enclosure, which connects to the
primary display using a quick connect cable
•
Mounting the temperature sensor to the display structure and at least one
foot away from the display is preferred – terminate it to the primary display
with a quick connect cable (
Do Not
mount the temperature sensor between
display, or anywhere that the airflow is restricted)
•
The primary display will connect to the mirror display (2V installations)
with a 6-foot, quick connect, inter-connect cable. In the case of those cables
that have right-angle connector, make sure the cable extends to the side or
down (never up) to prevent stress on the cable
A separate manual is provided for explaining the connection to the signal termination
enclosure. There are seven different methods of communication; your manual will be
one of these types:
