2. Cable selection
D Always use an external cable (A66L–6001–0026#) when the cable
is to be laid outside the power magnetics cabinet or main unit
cabinet, where it may be pulled, rubbed, or stepped on.
D Use an external cable when part of the cabling is to be subject to
movement. For example, when connecting a portable
operation
pendant box to the power magnetics cabinet, the use of an external
cable is desirable because the cable is likely to be bent, pulled, or
twisted repeatedly even though frequent system operation is not
expected. However, the force likely to be applied when the cable
is installed or moved for maintenance purposes does not need to be
taken into consideration.
D Use an external cable in locations where sparks or flame are a
danger. Although the internal cord type cable
(A66L–6001–0023#) is covered by nonflammable resin, the cover,
if exposed to frame for a long time, may melt, allowing the fiber
cable inside to burn.
D Use an external cable when the cable is expected to be pulled with
considerable force during installation (the force applied to the cable
must be within the specified tensile strength limit at all times). For
example, even though installing a cable in a cable duct can be
regarded as internal cabling, a cable of the appropriate type must
be selected according to the tensile force to be applied to the cable
during installation.
D Both the internal cord type and external cables have the same oil
and heat resistance properties.
