It is the responsibility of the person installing the ASD or the electrical maintenance personnel to
provide proper grounding and branch circuit protection in accordance with the 2002 NEC and
applicable local codes.

ASD when the power is on.
If the ASD should emit smoke or an unusual odor or sound, turn the power off immediately.
The heat sink and the discharge resistors may become extremely hot to the touch. Allow the unit to
cool before coming in contact or performing service on these items.
