Safety Information and Precautions
W7B ASD Installation & Operation Manual
Operational and
Maintenance Precautions
• Turn off and lock out/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
the front door-mounted Charge LED. 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 on the power 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 the TIC Customer Support
Center 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 off the power 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.
• Ensure that the Run functions (F, R, Preset
Speed, etc.) of the ASD are off before
performing a Reset. The post-reset settings
may allow the ASD to start unexpectedly.
• Retry or Reset settings may allow the motor
to start unexpectedly. Warnings to this effect
should be clearly posted near the ASD and the
motor (see
for more information).
• In the event of a power failure, the motor may
restart after power is restored.
• The system should be inspected periodically
for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors
are tightened securely.
DO NOT
install, operate, perform maintenance, or
dispose of this equipment until you have read and
understood all of the product warnings and user
directions. Failure to do so may result in equipment
damage, operator injury, or loss of life.
