Always use ‘star’ washers with fasteners, Use nuts and bolts whenever possible.
Apply even torque to fasteners to avoid distorting the Mounting Plate.
Re e ber to leave enough space around the front of the NiTRO Syste so the door can be easily
installed, accessed, locked, and that the co rad™ can slide out freely.
When bolting the Mounting Plate through a sheet etal surface, use ‘fender’ washers on the back of
the sheet etal to help spread the torque load.
Route the power harness, ca era harness(es), and accessory harness(es) through the Rear Door to
the installation destination(s).
Leave enough cable slack at the Rear End Cap,12 inches.
Check for:
Safety
Not blocking passenger or driver access
Not obstructing driver’s view
Will not snag loose clothing or carry-on ite s
Accessibility
To the NiTRO 900 front panel for configuring & downloading
For easy co rad™ re oval and insertion

Generally at the front of the Bus beside the front ca era, as close to the center as possible.
 Be sure to stagger the IR relevant to the front ca era so as to allow easier access to the ca era
do e screws and IR Illu inator screws.
 Avoid areas where artificial light ay cause “confusion” for the IR Illu inator which will affect the
proper function of the Illu inator.
 Position the IR Illu inator so that there is an unobstructed view to the back of the bus. Illu inator
should be ai ed towards the E ergency Exit sign at the back of the bus.
Bracket ust be securely fastened to the ceiling or bulkhead.
Power connector should be inside bulkhead or pushed into ceiling cavity.

Constant Power connection MUST ALWAYS be ade directly to battery.
NOTE:
NOTE:NOTE:
NOTE: On rear engine buses, an alternative 12V source in the power distribution panel can be utilized.
However, connection will vary fro installation to installation.
Always use gro ets when running the harness through sheet etal holes.
Avoid excessively tight bends especially around etal surfaces.
Use fuse holder and the 15 A p fuse provided on the 12V+ connection (do not exceed 15 A p fuse).
Connect fuse as close to power source as possible.
Use cable ties to secure harness and fuse holder.
Use correct ter inal size for wire gauge.
10-12 AWG = Yellow
14-16 AWG = Blue
18-22 AWG = Red
Use ratcheting cri pers for ter inal installation.

-16-
If grounding to a painted surface, scrape off paint and use ‘star’ washer between ter inal and
etal surface.
DO NOT use painted or anodized fasteners.
Before connecting constant power, cut off excess slack.
Before connecting power directly at battery, verify that the syste aintains a ini u of
10Volts during engine cranking. Testing requires starting the bus, with a ulti eter connected to
battery. Confir voltage does not drop below 10V during cranking. If voltage drops, advise
echanic at bus garage that the batteries ay need to be replaced.

absorb vibration and aid in eli ination of wind noise fro the roof of the
bus. Deter ine seat position for ca era harness and insert ca era
