Installation
Mounting
The front plate provides four holes with a diameter of 1/8” (3.2 mm) for screw mounting. Use
the four (4) provided screws for mounting. Use minimum 2.6 lb-in (0.3 N-m), maximum 3.5 lbin (0.4 N-m) torque. Before mounting, plug the connector plate into the LIM. Refer to Figures 1
and 2 for dimensions, listed in inches (mm).

Wiring
The LIM2010 connects to a connector plate assembly. Use the proper wiring diagram to connect to the assembly. Before mounting the LIM, plug the connector plate into the LIM.
Connector Plate
Actual cable length for connector cables is 20” (50.8 cm). Both plugs are connected to
LIM2010. Connector plate must only be installed in a grounded, metallic enclosure.
Figure 3 - Connecting connector plate plugs to LIM2010
Figure 4 shows wiring the connector plate for basic installation with no accessories. If other equipment is to
be installed, such as remote indicators, fault location, or
load monitoring, or for more information on the connector plate and installation, refer to the LIM2010 user
manual.
Connector plate L1 and L2 connect to the main lines
of the system, on the secondary of the isolation transformer. Connector plate LIMGND and GND2 are sepa-
rate connections to the system ground.
