Common Bus Fusing Requirements
When using a Kinetix 6000 leader IAM, dc bus fuses are only required
when wiring to more than one Kinetix 6000 follower IAM. When
wiring multiple follower IAMs, terminal blocks are required to extend
the dc common bus power to additional drives. Fuses should be
installed in both lines of the dc bus between the dc bus terminal block
and each follower IAM. These fuses should be rated based on the dc
input current of each follower IAM.
When using a non-Kinetix 6000 common bus leader, dc bus fuses are
required in both lines of the dc bus, between the common bus leader
and follower IAM. These fuses should be rated based on the leader’s
dc output current. When using more than one follower IAM, fuses
should be installed in both lines of the dc bus between the
non-Kinetix 6000 common bus leader and the terminal block as well
as between the dc bus terminal block and each follower IAM.
Refer to Circuit Breaker/Fuse Specifications on page 177 for
recommended fuse sizes. Refer to DC Common Bus Wiring Examples
on page 197 for interconnect diagrams.
Setting the Ground Jumper
in Ungrounded Power
Configurations
Setting the ground jumper is only necessary when using an
ungrounded power configuration. Setting the jumper involves
removing the IAM from the power rail, opening the IAM, and moving
the jumper.
Setting the ground jumper is best done when the integrated axis
module (IAM) is removed from the power rail and placed face-up on
a solid surface equipped as a grounded static safe workstation.
To remove the IAM from the power rail, refer to Removing Power Rail
Modules on page 164.
ATTENTION
To avoid personal injury and/or equipment damage, remove the
IAM from the power rail before setting the ground jumper.
IMPORTANT
If you have grounded power distribution, you do not need to set
the ground jumper. Go to Grounding Your Kinetix 6000 System
on page 78
