Figure 18 shows the SSR1 solid state relay (P/N A15000SPI01). This relay is capable of interrupting up to 100A on
a 120/240VAC circuit. The relay is attached to the device requiring interruption via a Hubbell CS-6365C circular
power connector. Ground is attached to the green terminal, neutral is attached to the white terminal, incoming power
is attached to the XXX terminal, and switched power is available on the YYY terminal. The SSR1 provides charging
current and an AC synchronization signal to the SPI1.
Extreme caution must be taken when handling the relay after it has been in use. The unit will get extremely hot during
normal operation when a large load is being controlled. After interruption is complete and the relay connector is
disconnected from the load, the relay should be left to cool for 1 hour before the unit is handled with bare hands.
During operation, ensure that the heatsink fins on the bottom of the relay are exposed to adequate air flow, otherwise
the relay may overheat. If the relay does overheat, an internal thermal cut off will turn off the relay until the internal
temperature returns to an acceptable level.
Figure 18 Solid State Relay (SSR1) Connections
The SSR1 relay is also available with ring lugs terminating the individual conductor wires (P/N A15000SPI07), instead
of the circular power connector. Table 3 describes the function of each wire. A simplified schematic of the relay may
be found in Appendix B.

Earth Ground
This wire should be connected to a proper earth ground point for
safe operation.

Neutral (N)
Optionally connected to power system neutral. When connected,
the SPI1 will charge from the line power source. Only connect if
the voltage between N and L1 is /- 20V.
