Switch Box Relay wiring instructions

1. Connect ground to Green Terminal Block (See Figure 1)
   
2. Neutral Wire not needed, cap end of wire if supplied.
   
3. Connect 120v input power to Blue Terminal Block (See Figure 1), do not use high leg in three phase systems for supply (remove yellow warning label to access screw) (See Figure 2). WARNING: all 230 volt contactor coils require two separate phases to operate, this box provides phase A and phase B is connected to other terminal on 230 bolt contactor. If unable to switch same phase on all contactors continue to Step 4 to remove jumper and wire individual input and output on relay. Otherwise skip to Step 7.
   
4. Skip to Step 7 if jumper link is not required. Remove blue jumper link from common (11) on relay with flat blade screwdriver from relays (See Figure 3).
   
5. Remove jumper wire from Blue Terminal Block and relay
   
6. Connect supply side to common (11) on each individual relay (See Figure 4 for relay diagram).
   
7. Connect the output on each individual relay (14) to coil supply wire for each contactor (See Figure 4 for relay diagram).
