Installation Instructions
February, 2004
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 (
550-054) 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.
