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.
•
Remove power from the ASD during extended periods of non-use.
•
The system should be inspected periodically for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely.
