CAUTION
Be sure the power being supplied matches
the power required by the equipment.
CAUTION
Power supply cords and cables must be
protected. Do not run cords where they can
be walked upon. Protect cables against
pinching and chafing. Pay special attention
to locations where the cables enter or exit
an enclosure or make a sharp bend.
CAUTION
Ensure that the electrical supply is protected
by over-current protection devices as
required by the applicable electrical codes.
•
Secure all cables at close intervals along their entire
lengths.
•
Protect the cabling with additional sheathing or padding
anywhere it passes through a hole or lays against an
obstruction.
•
Provide flex relief at any location where the cable must
change direction sharply, to maintain a smooth bend and
prevent kinking.
•
Provide strain relief at each connector to absorb any
pulling forces on the cable and prevent damage to the
connector.
