WARNING
• Select wiring and/or cable glands that are rated for the environment
of use. Failure to use properly rated wiring and/or cable glands can
result in personal injury or property damage.
• Wiring connections must be in accordance with local, regional
and national codes for any given area. Failure to follow the local,
regional and national codes could result in personal injury or
property damage.
• To avoid personal injury resulting from electrical shock, never
connect the controller or associated equipment to a supply
source having a voltage greater than the maximum rated
voltage of this controller or the associated equipment. Make
sure that the components used in the electronic system are
compatible with and have the proper voltage rating.
