Common Bus Fusing Requirements

When using a Kinetix 6000 leader IAM module, DC-bus fuses are required only
when wiring to more than one Kinetix 6000 follower IAM module. When wiring
multiple follower IAM modules, terminal blocks are required to extend the DC
common-bus power to additional drives. Install fuses in both lines of the DC bus
between the DC bus terminal block and each follower IAM module. Base these
fuse ratings on the DC input current of each follower IAM module.

When using a non-Kinetix 6000 common-bus leader drive, DC bus fuses are
required in both lines of the DC bus, between the common-bus leader drive and
follower IAM module. Base these fuse ratings on the common-bus leader drive
DC output current. When using more than one follower IAM module, install
fuses 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 module.

Setting the Ground Jumper
in Ungrounded Power
Configurations

Setting the ground jumper is necessary only when using an ungrounded or high-
impedance grounded power configuration. Setting the jumper involves removing
the IAM module from the power rail, opening the IAM module, and moving the
jumper.

Setting the ground jumper is best done when the IAM module is removed from
the power rail and placed face-up on a solid surface equipped as a grounded
static-safe workstation.

IMPORTANT

If you have grounded power distribution, you do not need to set the ground
jumper. Go to Grounding the Kinetix 6000 Drive System on

page 93

.

ATTENTION: To avoid personal injury and/or damage to equipment, remove
the IAM module from the power rail before setting the ground jumper.

By setting the ground jumper for ungrounded power configurations, you no
longer maintain line-to-neutral voltage protection.
