Important Note:
It is essential to use the three (3) SBI # 51035 relays to make the connection as in 3-relay diagrams. It is possible to
use two relay White Rodger (SPNC / SPNO # 90-380) for the two-relay diagram. The use of another brand or model of
relay is not recommended since very limited technical support may be provided.
