4-2 INSTALLATION
CONNECTIONS
Incorrect wiring may result in damage to the relay. Typical internal connections are shown in Figures 4-13
through 4-15. Typical ac connections are shown in Figure 4-16. Typical dc connections are shown in Figure
4-17. Be sure to check model and style number against the options listed in the Style Number Identification
Chart before connecting and energizing a particular relay. Connections should be made with 14 AWG
stranded wire or better.
NOTE: Be sure the relay case is hard-wired to earth ground with no smaller than 12 AWG copper wire
attached to the ground terminal on the rear of the relay case. When the relay is configured in a
system with other protective devices, always use a separate lead to the groung bus from each relay.
