CONNECTIONS
Typical ac input and dc control connections are shown in Figures 4-6 and 4-7. Refer to the block diagram
in Section 3 for relay internal connections.
Figure 4-6. AC Input Connections
NOTE
Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWG
copper wire attached to the ground terminal on the rear of the unit case. When
the relay is configured in a system with other devices, it is recommended to use a
separate lead to the ground bus from each unit.
