NOTE
If using a semiconductor switch type, pay attention to the proper polarity. A relay or other
mechanical control is preferred.

The relay output contacts must not be connected to any utility connected circuits; the utility requires
reinforced insulation. The relay output contacts have a maximum rating of 30 Vac/1A and 60 Vdc/2A nominal
values.
