Operational and Maintenance
Precautions
• Turn off, lockout, and tag out the main power, the control power, and instrumentation connections
before inspecting or servicing the drive, connecting or disconnecting the power wiring to the
equipment, or opening the door of the enclosure.
• The capacitors of the ASD maintain a residual charge for a period of time after turning off the ASD.
The required time for each ASD typeform is indicated with a cabinet label and a Charge LED
(Shown for smaller ASDs in
Figure 2 on pg. 14 ; LED is located on the front panel of larger ASDs).
Wait at least the minimum time indicated on the enclosure-mounted label and ensure that the
Charge LED has gone out before opening the door of the ASD once the ASD power has been
turned off.
• Turn the power on only after attaching (or closing) the front cover and DO NOT remove or open
the front cover of the ASD when the power is on.
• 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.
• If the ASD should emit smoke, or an unusual odor or sound, turn the power off immediately.
• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool
before coming in contact with 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.
