• Use lockout/tagout procedures on the branch circuit disconnect before servicing the ASD.
• The ASD maintains a residual charge for a while after turning the ASD off. Wait at least five minutes
before servicing the ASD after turning the ASD power off. Ensure that the Charge LED is off.
• Do Not attempt to disassemble, modify, or repair the ASD. Call your Toshiba sales representative for
repair information.
• Do not place any objects inside of the ASD.
• Turn the power on only after attaching the front cover and Do Not remove the front cover of the 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.
• 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.
