The following diagrams illustrate three earthing systems for the 230VAC TN
network power grid with which the LCS is compatible. These three earthing
systems are described as follows:
TN-S: Separate Neutral and Protective Earth conductors are connected only at
the service panel or other primary electrical distribution point. Each conductor
is separately routed and wired to the corresponding Neutral and Protective Earth
conductors on the LCS.

TN-C: A combined Protective Earth and Neutral conductor (PEN) is run from
the primary electrical distribution point to the LCS. The Neutral and Protec-
tive Earth conductors must be separated at this point in order to connect to the
corresponding Neutral and Protective Earth conductors provided with the LCS.
