LINE VOLTAGE
Line and Load Circuit Wiring
EZ-MAX Plus relay cabinets have multiple relay circuits of a specific type depending on
the cabinet model. For details of the different relay types, their capacities, and
permitted wire sizes, please see “Wire Sizes and Capacities for Relays” on page 18.
Testing the Circuits
Verify that all load and feed connections have been made before you attempt to
connect any circuit to a relay. Test each circuit in the cabinet by following this
procedure:
Step 1: Turn off the breaker feeding the circuit
Step 2: Ensure that all connections and wiring between the relay cabinet and
the circuit breaker panel are complete
Step 3: Ensure that all connections and wiring between the relay cabinet and
the load are complete.
Step 4: At the relay cabinet, connect the feed(s) for relay #1 to the load for
relay #1 with a wire nut or other appropriate means.
Step 5: Turn on the circuit breaker to energize the circuit.
Step 6: Resolve any mis-wiring, shorts, etc. for the connected circuit.
Step 7: Repeat the above steps for all circuits in all relay panels for your
system. When all circuits have been tested, disconnect all Lines from
Loads and proceed to the next section.
Installing Relay Cards
On several relay cabinet models, the relays are removable. If you have one of these
cabinets and need to add or remove relay modules, please follow these instructions:
Step 1: Locate the appropriate location for the relay card
Step 2: Align the connector from the relay card with the relay bus board and
gently push the two together.
Step 3: Once firmly seated, use a phillips screwdriver to tighten the mounting
screw.
