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.
Ó
Warning: All high-voltage outputs must be powered by the
same source (phase), as shown in the example above.
