CAUTION:
The LRC DOs control 24 Vac loads only. The maximum rating is 12 VA for each DO. Use an interposing
220V 4-relay module (540-147) for any of the following: VA requirements higher than the maximum; 110
or 220 Vac requirements; DC power requirements; separate transformers used to power the load.
NOTE: Consult with the local representative if terminations are missing or are different.

CAUTION:
If the LRC is not connected as shown, it is not resistant to electrical surges. It is also
susceptible to interference from other equipment.
