Precautions
• Turn off and lock-out/tag-out the main power, the control power, and instrumentation connections
before inspecting or servicing the ASD, removing any enclosure panels, or connecting/
disconnecting the power wiring to the equipment.
• Turn the power on only after attaching (or closing) the front cover. DO NOT open or remove the
front cover or any of the enclosure panels of the Q9 Plus Bypass ASD/Q9 Plus Bypass Box during
normal operation.
• During system setup, calibration, testing, or troubleshooting, it may be required to access live
circuits. DO NOT leave the system unattended and powered with the door(s) and/or covers
removed.
• If/when taking a live reading is required (equipment is powered), it is to be performed by Qualified
Personnel ONLY. Proper and approved personal protection equipment is to be used by trained
personnel for all electrical measurements.
• The capacitors of the Q9 Plus Bypass ASD/Q9 Plus Bypass Box maintain a residual charge for a
period of time after the Q9 Plus Bypass ASD/Q9 Plus Bypass Box is powered off. The required
time for each system typeform is indicated with a cabinet label and a Charge Indicator LED. Wait
at least the minimum time indicated on the enclosure-mounted label and ensure that the Charge
Indicator LED has turned off once the ASD power has been turned off before coming into contact
with any circuits.
• DO NOT attempt to disassemble, modify, or repair the system. Contact the TIC Customer Support
Center for repair information.
• DO NOT place any objects inside of the Q9 Plus Bypass ASD/Q9 Plus Bypass Box.
• If the system 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 into contact with these items.
• Remove power from the Q9 Plus Bypass ASD/Q9 Plus Bypass Box during extended periods of
non-use.
• Inspect the system annually (as a minimum) for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely. Inspect more frequently when
operating in a harsh environment or when used on a high-output-demand application.
• Ensure that the Run functions (F, R, Preset Speed, etc.) of the Q9 Plus Bypass ASD/Q9 Plus
Bypass Box are off before performing a Reset. The post-reset settings may allow the motor to start
unexpectedly.
• The Auto-Restart and Retry programmable functions of the ASD may allow for the system to
start or stop unexpectedly. Warning signs to this effect must be clearly posted at or near the
machinery/hazard.
• In the event of a power failure, the motor may restart after power is restored.
