Wiring the Relays
Step 1: Connect the line (feed/circuit breaker) side of the circuit to the “input”
terminal(s) on the relay card.
Step 2: Connect the load side of the circuit to the "output" terminal(s) on the
relay card.
Step 3: Please note that relay card terminals accept the following wire sizes:
Figure 7: Wire Sizes and Capacities for Relays
Step 4: Circuit neutrals may follow the path of the line load conductors through
the relay panel or the line/load conductors may pass back to the
panelboard to be joined with the neutral to the load.

If you need to remove the installed relay cards that shipped
from the factory, remove the shipping screw located near the
connector and discard. This screw is only required for
shipping and not for installation.
MISWIRING THE RELAY MODULES WILL
CAUSE DAMAGE TO THE RELAY MODULE,
THE RELAY CABINET, AND POSSIBLY
OTHER SYSTEMS!
When driving secondary contactors, EMF may
induce significant noise which may cause some
units to reset. Installation of MOV may be
required. Please contact Leviton support for
additional details.
