CHAPTER 1 IMPORTANT SAFETY
INFORMATION
Read this manual and the operation and safety instructions included with your implement and/or controller
carefully before installing the SC1™ HD system.
• Follow all safety information presented within this manual.
• If you require assistance with any portion of the installation or service of your Raven equipment, contact your
local Raven dealer for support.
• Follow all safety labels affixed to the SC1 HD system components. Be sure to keep safety labels in good
condition and replace any missing or damaged labels. To obtain replacements for missing or damaged safety
labels, contact your local Raven dealer.
When operating the machine after installing SC1 HD, observe the following safety measures:
• Be alert and aware of surroundings.
• Do not operate SC1 HD or any agricultural equipment while under the influence of alcohol or an illegal
substance.
• Remain in the operator’s position or a safe working distance away from the booms at all times when SC1 HD is
engaged.
• Disable SC1 HD when exiting from the operator’s seat and machine.
• Do not drive the machine with SC1 HD enabled on any public road.
• Determine and remain a safe working distance from other individuals. The operator is responsible for disabling
SC1 HD when the safe working distance has diminished.
• Ensure SC1 HD is disabled prior to starting any maintenance work on SC1 HD or the machine.
• When starting the machine for the first time after installing SC1 HD, be sure that all persons stand clear in case
a hose has not been properly tightened.
• The machine must remain stationary and switched off, with the booms unfolded and supported, during
installation or maintenance.
NOTICE
WARNING

CHAPTER 1

GENERAL
• Always verify that the power leads are connected to the correct polarity as marked. Reversing the power leads
could cause severe damage to the equipment.
• Ensure that the power cable is the last cable to be connected.
• A minimum of 12 VDC is required for system operation with a maximum of 15 VDC.
INSTRUCTIONS FOR WIRE ROUTING
The word “harness” is used to mean all electrical leads and cables, bundled and unbundled. When installing
harness, secure it at least every 30 cm (12in) to the frame. Follow existing harness as much as possible and use
these guidelines:
Harness should not contact or be attached to:
• Lines and hoses with high vibration forces or pressure spikes
• Lines and hoses carrying hot fluids beyond harness component specifications
Avoid contact with any sharp edge or abrading surfaces such as, but not limited to:
• Sheared or flame cut edges
• Edges of machined surfaces
• Fastener threads or cap screw heads
• Ends of adjustable hose clamps
• Wire exiting conduit without protection, either ends or side of conduit
• Hose and tube fittings
Routing should not allow harnesses to:
• Hang below the unit
• Have the potential to become damaged due to exposure to the exterior environment. (i.e. tree limbs, debris,
attachments)
• Be placed in areas of or in contact with machine components which develop temperatures higher than the
temperature rating of harness components
• Wiring should be protected or shielded if it needs to route near hot temperatures beyond harness component
specifications
Harnessing should not have sharp bends
Allow sufficient clearance from machine component operational zones such as:
• Drive shafts, universal joints and hitches (i.e. 3-point hitch)
• Pulleys, gears, sprockets
• Deflection and backlash of belts and chains
• Adjustment zones of adjustable brackets
CAUTION

IMPORTANT SAFETY INFORMATION
1
• Changes of position in SC1 HD and suspension systems
• Moving linkages, cylinders, articulation joints, attachments
• Ground engaging components
For harness sections that move during machine operation:
• Allow sufficient length for free movement without interference to prevent: pulling, pinching, catching or
rubbing, especially in articulation and pivot points
• Clamp harnesses securely to force controlled movement to occur in the desired harness section
• Avoid sharp twisting or flexing of harnesses in short distances
• Connectors and splices should not be located in harness sections that move
Protect harnesses from:
• Foreign objects such as rocks that may fall or be thrown by the unit
• Buildup of dirt, mud, snow, ice, submersion in water and oil
• Tree limbs, brush and debris
• Damage where service personnel or operators might step or use as a grab bar
• Damage when passing through metal structures
IMPORTANT:
• Avoid directly spraying electrical components and connections with high pressure water.
High pressure water sprays can penetrate seals and cause electrical components to corrode
or otherwise become damaged. When performing maintenance:
•Inspect all electrical components and connections for damage or corrosion. Repair or replace
components, connections, or cable as necessary.
•Ensure connections are clean, dry, and not damaged. Repair or replace components,
connections, or cable as necessary.
•Clean components or connections using low pressure water, pressurized air, or an aerosol
electrical component cleaning agent.
•Remove visible surface water from components, connections, or seals using pressurized air
or an aerosol electrical component cleaning agent. allow components to dry completely
before reconnecting cables.
