Common Bus Fusing Requirements
When using a Bulletin 2094 leader IAM power module, DC-bus fuses are
required only when wiring to more than one Bulletin 2094 follower IAM
module. When wiring multiple follower IAM modules, terminal blocks are
required to extend the DC common-bus power to additional drives. You should
install fuses in both lines of the DC bus between the DC bus terminal block and
each follower IAM module. These fuses should be rated based on the DC input
current of each follower IAM module.
When using a non-Bulletin 2094 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. These fuses should be rated based on the common-bus
leader drive DC output current. When using more than one follower IAM
module, fuses should be installed in both lines of the DC bus between the non-
Bulletin 2094 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 power module from the power rail, opening the IAM module, and
moving the jumper.
Setting the ground jumper is best done when the IAM power 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 Modular Drive System on
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.
