Section 3 INSTALLATION
3.1 PREPARING FOR INSTALLATION
To begin the installation, unpack all the equipment for installation. Ensure you have all the
tools and materials required to complete the installation. The tools are listed in paragraph
2.2 Tools.
The cabinet does not have to be in flash, and the DA-400™ is designed to be
installed while the intersection is running if the user takes all appropriate IMSA and MUTCD
recommended safety precautions. Follow all applicable and appropriate State DOT/local
agency rules and procedures for working in an operational Traffic Control Cabinet, with the
potential of creating a fault condition that could cause a flash condition in the cabinet.
Different administrative agencies will have different guidelines and requirements up to and
including having a Law Enforcement Officer on-site for traffic control in the event of a traffic
signal cabinet service interruption. Preparations should be made to correctly identify and
note the locations of all field wiring terminations, before the DA-400™ wiring harnesses
installation begins.
CAUTION:
Care should be taken to make sure that critical 24 VDC and 120 VAC are
not disturbed or disrupted, or the cabinet may potentially go into a flash, failure or
fault condition.
3.2 PLACING THE DA-400™ INTO THE CABINET
Determine where the DA-400™ will be placed in the cabinet. It may be located anywhere in
the cabinet there is space available for the unit. The floor of the cabinet should be avoided
due to the potential for water intrusion. The unit should be placed in a location allowing air
to circulate freely around it. The leads for all wire harnesses are 8 feet (2.4 meters) in
length so the position of the DA-400™ should be located such that all required connections
can be terminated based on its position inside the traffic control cabinet. Once a location is
established, the DA-400™ can be placed on the shelf, or mounted on the side rail of the
rack assembly. A mounting ear is supplied. Screw the mounting ear onto the DA-400™
and
attach the device to the side of the equipment rack.
3.3 CONNECTING THE DA-400™ HARNESSES
Once the DA-400™ is placed into the cabinet, the next step will be to wire in the two (2)
connection harnesses. Each harness has a different sized connector pin-out and wire color
code to prevent cross wiring. Each wire is also marked with printed lettering to indicate the
specific function of the wire and its associated monitoring termination point. These marks
provide information to where the wires need to be terminated within the cabinet. The
harnesses are labeled: H5 and H7. The following is the wiring information for each harness.
Not all the connections on each harness will be connected on every installation. For
example, if there is no Battery Backup System (BBS) in the cabinet, none of these wires
will have a place to be connected. All unused wires should be looped and tied back.
CAUTION: DO NOT CUT BACK HARNESS WIRES. Leave wiring intact for possible
future installation.
CAUTION: Do not plug the harnesses into the DA-400™ until all terminations are
completed. It is also good practice to make sure the correct voltages are on each
wire before connecting the harness to the DA-400™. All AC voltages are for 120 VAC
connections.
