Section 2: Rear Mounted
Connections
When making bolted connec-
tions to the equipment or to the
adapters themselves, all which
have pre-tapped holes, it is
important not to exceed the rec-
ommended torque values. In
addtion, any connection hard-
ware used should be the exact
length required and not extend
out past the mounting hole.
Failure to follow these require-
ments could result in equipment
damage and/or failure.
It is recommended that appropriate
interphase barriers be installed
between inside and outside primary
terminals with all rear connected
configurations to insure insulation
integrity. If interphase barriers are
ordered from Eaton, installation
instructions are provided with the
barriers (IL01301021E).
Straight Bus Adapter
Proceed with the following 3 steps:
Step 1: Bolt a straight bus adapter
to the vertically positioned mounting
holes of a primary terminal pad as
shown using the hardware provided.
Torque the bolted connection to 120
in-lbs (13.6 N-m) using a torque
wrench.
Step 2: Complete all six adapter
connections (eight for 4-pole) in a
similar fashion with the three line
adapters pointing up and the three
load adapters pointing down as
shown.
Step 3: Reverse the procedure just
described to remove the adapters.
