A variety of electrical devices can be
installed on the input and output of the
drive. Some are required for safety and
protection while others are optional
depending on the installation.
Connection of peripheral devices is
shown below. A description of each is
provided in Table 2-1. See Section 5.2.3
for recommended sizing of cable,
breakers and fuses.
WARNING
• Install protection devices (a fuse) at
power input to the drive. The protection
devices must provide protection from
short-circuit, and be able to completely
isolate the drive from the electrical
power input. See Table 5.2.3a for
required and recommended breakers,
fuses and cable.
