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 lb-
in (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 con-
nect to the assembly. Before mounting the LIM, plug the connector plate into the LIM.
Figure 4 shows wiring the connector plate for basic in-
stallation 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 con-
nector 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 trans-
former. Connector plate LIMGND and GND2 are sepa-
rate connections to the system ground.
!DANGER
• Disconnect all power before servicing.
• Reference NFPA 99 / CSA Z32 for
Installation Standard.
