Screen Blanking Cable
When routing any additional cables for screen blanking:
• Route the cable the shortest way possible removing any left-over cable
• Fuses and cabling are user supplied. Therefore, route these cables so they are
protected from physical damage and from surfaces that might exceed the cable's
rated temperature threshold.
• Cable should be protected from physical damage from moving parts
• Do not expose the cable to chemicals or oil that may cause the wiring insulation to
deteriorate
• Always route the cable so that it does not interfere with safe operation and
maintenance of the vehicle.
• Provide mechanical support for the cable by securing it to the vehicle structure at
approximately one foot intervals, taking care not to over tighten and pinch
conductors or penetrate outer cable jacket.
Honeywell Screen Blanking Box Cable
An optional Honeywell Screen Blanking Box Cable is available.
Caution: For installation by trained service personnel only.
Warning: For proper and safe installation, the input power lead to the
Screen Blanking Box requires a 3 Amp maximum time delay
