CONNECTIONS
Verify the relay model and style number before connecting and energizing the relay. Incorrect wiring may
result in damage to the relay. Except where otherwise noted, connections should be made with minimum
wire size of 14 AWG.
Internal Connections
Internal connections/terminal assignments for a single-phase relay are illustrated in Figure 4-13. Internal
connections/terminal assignments for a three-phase relay are illustrated in Figure 4-14. These figures
may show options that may not apply to your relay.
Control Connections
Typical dc control connections are shown in Figure 4-15.
Sensing Connections
Typical sensing current connections for a single-phase application are shown in Figure 4-16.
Three-phase sensing current connections are illustrated in Figures 4-17 and 4-18. Figure 4-17 shows the
sensing inputs connected in a wye configuration. Figure 4-18 shows the sensing inputs connected in a
delta configuration.
