Understanding Basic
Wiring Requirements
This section contains basic wiring information for the 1394.
ATTENTION
!
Plan the installation of your system so that you can
perform all cutting, drilling, tapping, and welding
with the system removed from the enclosure.
Because the system is of the open type construction,
be careful to keep any metal debris from falling into
it. Metal debris or other foreign matter can become
lodged in the circuitry, which can result in damage to
components.
IMPORTANT
This section contains common PWM servo system
wiring configurations, size, and practices that can be
used in a majority of applications. National Electrical
Code, local electrical codes, special operating
temperatures, duty cycles, or system configurations
take precedence over the values and methods
provided.
