. Make sure that the ratings,
settings, and interface options on the Load Break Switch
nameplate (see Figure 06) are correct for the planned
installation.
2.
Perform High-potential Withstand Tests
. Before installing the
NOVA LBS switch, perform withstand voltage tests. Refer to
the Service Information section for withstand voltage test
procedures.
3.
Install the Switch Under Load
. Install the Switch on Cooper

Follow all locally approved safety procedures when lifting and mounting
the equipment. Use the lifting lugs provided. Lift the unit gently and do
not allow it to shift. Incorrect lifting may cause damage to the
equipment.
Moving the Switch
NOVA LBS switches are transported on pallets (bolted onto them).
When moved by forklift truck, the switch must remain bolted to the
pallet to prevent damage to the OPEN/CLOSED position indicator. Eaton
recommends carrying NOVA LBS switches in the closed position to
maximize the operating performance of the unit.
CAUTION
Risk of tipping over. High center of gravity. Use a 4-point lash to prevent
the unit from tipping over during lifting operations. Incorrect lifting may
cause personal injury or damage to the equipment.
Lifting the Switch
Follow all approved safety procedures and practices when securing and
lifting the equipment. Lift the unit smoothly and do not allow it to shift.

1.
Ground the NOVA LBS Load Break Switch
. Ground the
grounding connector. The ground connector is located at the
back of the mechanism housing. Improper grounding can
cause equipment damage and malfunction.
•
See Figure 5 for the location of the grounding
connector.
•
See Figures 11, 12, and 13 for the recommended
ground connection for the NOVA LBS Load Break
Switch.
2.
Install the Controller
. Refer to the control installation manual
and install the control. Make sure that the control cable is
connected between the control and the Load Break Switch,
that the control is correctly programmed for the planned
installation, and that the control is grounded.
To ensure proper installation of this cable, securely fasten the aluminum
cable coupler ring (Figure 7).
