Preparing for Installation
Preparing for Installation
PSA components mount in various locations inside and outside the bus (consult the "System Diagram" on page 6). Use
the following information to help avoid mounting problems and harness-routing obstacles.
IMPORTANT: Vehicle-specific planning
Important aspects of a PSA installation depend on implementation details, including:
•
School bus body and cab interior configuration
• Vehicle mechanical/electrical design
• Pre-existing equipment
Before proceeding, carefully consider the following guidelines and recommendations, and discuss component
mounting locations with the customer.
System Mounting
• Allow physical space around components and account for bulky I/O harnesses, wiring, fuse holders, and connectors
• Do not block operator sight lines (windows/mirrors)
Specific component requirements are covered in the mounting procedures (see
"Installing Components" on page 9).
Harness Routing
After determining component locations, plan harness and cable routes (see the "System Diagram" on page 6 and the
• Consider routing distances and logistics, including barriers/bottlenecks.
•
Plan for efficient access to battery source/ignition, power relays, and interface panels; choose power/ground
connections and fuse placement to limit the number and bulkiness of runs, particularly where space is limited.
• Manage harnesses and channel wiring to keep runs tidy and avoid cable damage.
NOTE: Component mounting
Select the SAM controller location first
.
Important cabling decisions and component locations depend on where the SAM controller is mounted. Determine the
SAM location before planning for other components.
Place the SAM Controller, Amplifier, and Ground Loop Isolator in proximity.
The amplifier must be mounted within 10 inches of the isolator unless a cable extension is used on the isolator pigtail
(for details, see "Audio Harnesses" on page 17).
Radar modules mount on the driver’s side exterior panel (min. 10ft. from front bumper, typically under the stop arm)
.
