General Description and Specications
The SHADOWRTB is designed to provide high intensity emergency scene lighting with quick
precision. As with any electromechanical device, take precautionary steps to ensure safe
operation.
e vehicle provides power for the 12 VDC circuitry. A 15 Amp breaker is recommended.
e umbilical corded control unit is powered via 12 VDC eliminating hazardous voltage
levels within the hand held control box.
The SHADOWRTB is manufactured to provide years of service with a minimum of maintenance.
Model # Description Minimum Power Requirements
SL422A 2 x LED 6 Amps, 120 VAC
SL442A 4 x LED 10 Amps, 120 VAC
Operation
Raising the light from the nested position
Using the control box, raise the lower stage. Control switches are of momentary action style and must
be held in the “on” position to actuate the stages.
The SHADOWRTB has an override system that precludes rotation of the lamp tree until the lower
stage has elevated approximately 16" from the nested position. When the lower stage is below 16" the
following conditions exist:
• Lamp Tree is prevented from rotating.
• All lights are turned off, including strobe light if equipped, regardless of light switch positions.
• Prevents the lower stage from moving down if lamp tree is not centered.
If the supply from the vehicle is marginal, position the SHADOWRTB before turning on lights.
Returning the light to the nested position
The KNIGHT2is equipped with an Autopark function as a standard feature. The “P” button on the
control box initiates the Autopark sequence. Once initiated, the “Emergency Stop” button indicator
is illuminated. Pressing the “Emergency Stop” button will cancel the Autopark sequence.

USER GUIDE
8
Autopark Sequence
Press green button on the controller once. It does not need to be held in position. The Autopark
sequence begins:
1. “Emergency Stop” light is illuminated.
2. Lamps are extinguished.
3. Upper stage begins rotation to the center position. If equipped with back light option, back light
begins oscillation and returns to the home position.
4. Once upper stage is centered, rotation stops, lower stage begins retracting.
5. After lower stage has fully retracted, upper stage begins retracting. Upon upper stage retracting fully,
“Emergency Stop” light turns off.

Installation
The SHADOWRTB must be installed by a designated installation facility or by an EVT certied Level
FA4 Technician. All safety precautions must be thoroughly understood before installation. Please
consult the factory for additional installation information assistance.
Improper installation can cause overheating of electrical power wires that could catch re and void the
warranty.
Ensure all wiring is properly protected with correct sized breakers and fuses before connecting to the
power source.
AC powered light towers require a high current draw to provide high levels of lighting. Verify all
connected electrical components are able to handle the load for this light tower as listed in the Technical
Specications on page 17.
If in doubt, contact Command Light at 1-800-797-7974 or [email protected].

Installation Notes
The SHADOWRTB weighs approximately 75 pounds. Use mechanical assistance such as a
forklift or crane to lift the light into installation position.
Use the provided fender washers under the mounting surface to distribute the weight load evenly.
When routing the connecting electrical wires take care to avoid sharp bends, hot components or other
hazards to the wire.
The SHADOWRTB is not designed to be operated in a raised position while the vehicle is in motion.
The SHADOWRTB includes warning circuit wiring to enable a warning device.
Location Requirements
The standard SHADOWRTB can be mounted on any location that is 34" x 22". The surface should be at
or have only a slight crown. For a recessed installation allow for a minimum of 60" x 38". Consult with
factory before construction of recessed installation. Verify all dimensions before installation to assure
proper operation of light will not infringe on other installed components. For all other installations
refer to the dimensional drawingon page 18 of guide that represents your particular model of light.
The drawings reect the dimensions of the “working envelope” of a typical light. Endure sufcient
clearances are incorporated in your installation to allow for variations (vehicle body ex, environmental
conditions, future servicing needs, etc.)
Four mounting bolts are required. Additional holes may be drilled in the frame ends if necessary to clear
obstructions.
Access holes for the power cord cabling should be in close proximity to the entrance box on the light.
Installing the cords with a sweeping 90° or 180° bend will provide better results.
The control box holster should be mounted in an area shielded from the weather. Allow a minimum of
10" clearance above the control box holster mounting location for easy access to the controller.

SHADOWRTB
11
Mounting
Place the provided spacers in the location of the light
mounting holes. The spacers may be modied to
conform to the contour of the mounting location.
Remove any obstructions below the mounting surface
such as headliners.
Attach any necessary lifting attachments to the
SHADOWRTB. The center of gravity (balance point) is
slightly below the rotation assembly.
Slowly lift the SHADOWRTB and check
for balanced lifting. Lower and make any necessary
adjustments to the lift points.
Lift and place the SHADOWRTB into position above the spacers. Before placing the full weight of the
light tower on the spacers, align spacers with the holes in the end frame castings.
Drill 21/64" holes in the mounting surface using the end casting holes as a template.
Fasten the light using the provided hardware. To assure a weather-tight installation apply a thin bead of
silicone based gasket sealer to the base of the spacer and underside of bolt head.
Remove any lifting straps and devices from the SHADOWRTB.
Locate and drill the wire feed holes.
Holster Mounting
Using the holster as a template, mark locations of holes.
Drill 17/64" mounting holes.
Drill any holes required to route the control wire from the control box to the SHADOWRTB.
Mount holster box with provided hardware.

Electrical Wiring
Please Note: Detailed internal wiring schematic for the light is found in the supplement pages found at
the end of this document.
Run the control wire from the control box holster to the SHADOWRTB.
Run the power wire from the breaker box or generator to the SHADOWRTB. A 15 Amp breaker is
recommended on AC LED models.
Make the control cable connections in the SHADOWRTB relay box by matching each control wire to its
same color on the connector block of the SHADOWRTB relay box.
The SHADOWRTB model SL422A and SL442A comes pre-wired to connect to 120 VAC. For 240 VAC
operation, remove the jumper between the two live wires at the AC input terminal block. If ordered with
220 VAC single leg (European) wiring, one wire in the AC input cable will not be used.
120/240 VAC 220 (Euro) VAC
Warning Device Installation
The SHADOWRTB nest sensor can be used to activate a warning device when the light is extended.
Typically the vehicle will have a light or buzzer that activates when the compartment doors are open.
The connector for hooking up a warning device is located in the holster box that holds the control unit.

SHADOWRTB

Maintenance
Cleaning
The SHADOWRTB is constructed with corrosion resistant aluminum and stainless steel fasteners. To
further enhance corrosion resistance all exposed surfaces receive a powder coated paint nish. To assure
years of trouble free service periodically clean all external surfaces with a mild detergent solution and
a gentle spray of water. DO NOT USE A HIGH-PRESSURE WASHER, which will force water into
sensitive electric circuitry.
Lamp lenses may be cleaned with any commercially available glass cleaner.
The lower stage actuator is a sealed unit and does not require adjustment or lubrication. They also have
a slip-clutch to compensate for minor stroke tolerances at the limits of its travel as well as internal limit
switches. The actuator may produce a ratcheting sound at each end of the stroke which is normal. The
actuator should not be made to ratchet excessively, this can lead to premature actuator clutch failure.
All pivot points on the SHADOWRTB are self-lubricating thermal polymer. Periodic cleaning with a
moisture displacing cleaner and soft bristle brush, without disassembly, to remove accumulated dirt and
debris will minimize wear.
Power Failure
The SHADOWRTB can be retracted manually if power to the unit is lost. If power loss is temporary,
reestablishing power may be easier than manually retracting the light.
Disconnect power source from the SHADOWRTB.
Rotate to Center
Slowly apply pressure to the midplate to manually rotate to the centered position. Trying to rotate the
midplate too quickly or with too much pressure can break the rotation motor shaft. Be certain that you
rotate the midplate in the proper direction as the lamp tree can rotate only 350˚.
Retract the Lower Stage
Locate the silver plug located on the actuator below the actuator’s motor. Use the provided hex tool
(6mm hex bit) to remove silver plug. Be sure to not lose this plug. Use the same hex tool inserted
into the opening to drive the internal gears of the actuator. Be sure to replace the silver plug after this
actuator is fully retracted.
