H9 ASD Installation and Operation Manual 9
Operational and Maintenance
Precautions
• Turn off, lock out, and tag out the main power, the control power, and instrumentation connections
before inspecting or servicing the drive, opening the door of the enclosure, or connecting/
disconnecting the power wiring to the equipment.
• The capacitors of the ASD maintain a residual charge for a period of time after turning the ASD off.
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. 16; 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 TIC 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.
•The Auto-Restart (F301) programmable functions of the ASD may allow for the system to start or
stop unexpectedly. Signs to this effect are to be clearly posted at the installation location.
• 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.
