WARNING:
To avoid damage to
property and equipment,
and/or injury of loss of
life, use National Electric

wiring practices to
install and operate the
Series 97. Failure to do
so could result in such
damage, and/or injury or
death.

Switching inductive loads
(relay coils, solenoids,
etc.) with the mechanical
relay, switched dc or
solid-state relay output
