Figure9-4 Binding cables where they must be bent
•
Route, bind, and attach excess cables for easy, safe maintenance activities and correct
operations.
•
Do not tie power cords to slide rails.
•
When you connect a cable to an articulated part, for example, when you connect a grounding
cable to a cabinet door, leave enough slack in cables and make sure they are not stressed from
any movement of the part.
•
Cables must be protected at points where they might rub or come in contact with sharp edges or
heated areas. Use high temperature cables near heat sources.
•
Securely fasten cables and take adequate measures to prevent loose connections.
Figure9-5 Securely fastening cables
