SM15 Rev. 4.00
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be
easily installed. Note that the hood is a "clamshell" hood and is installed after the wiring
is complete.
All wiring should be at least 24 AWG, except power and ground connections which
should be 20 AWG. Ensure that the ground connection is clean and well secured. To
prevent system failure or inadequate equipment protection, power to each component of
this system must be supplied from a separate breaker or fuse and not bundled to any
other source.
2.3.3
External Switches and Lamps
2.3.3.1
Transfer Switch
The transfer switch should be a positive action (SPST or SPDT) toggle or pushbutton
type, labeled as required. This switch is mandatory.
2.3.3.2
Lamp Dimmer Switch
The lamp dimmer switch should be a positive action, SPDT, toggle switch labeled DIM
on one side and BRIGHT on the other. This switch is not mandatory but is highly
recommended.
2.3.3.3
Lamp Test Switch
The lamp test switch should be a momentary action, DPDT, toggle or pushbutton switch
labeled LT TEST. This switch is not mandatory but is highly recommended.
2.3.3.4
Annunciators
Annunciators should be selected to suit the application. Note that a single switch/lamp
assembly can replace the transfer switch and annunciators. This should be a lighted
pushbutton switch (SPST/SPDT) with positive action (i.e., push on, push off), and two
legends to match the desired NAV functions. NAT P/N PB08-001 is recommended.
2.3.4
Post-Installation Checks
2.3.4.1
Voltage/resistance checks
Do not attach the RS08 until these conditions are met.
With the RS08 disconnected from its mating connector, check on pin 1 for +14/28 VDC
relative to ground and check pin 20 for continuity to ground (below 0.5 ohms).
