Warning: Use National Electric (NEC) or other country-spe-
cific standard wiring and safety practices when wiring and
connecting this controller to a power source and to electri-
cal sensors or peripheral devices. Failure to do so may
result in damage to equipment and property, and/or injury
or loss of life.
Note:
To prevent ground loops, maintain isolation from input to
