shall be performed by Qualified Personnel only.
Qualified Personnel shall be:
• Familiar with the construction and function of the ASD, the equipment being driven, and the
hazards involved.
• Trained and authorized to safely clear faults, ground and tag circuits, energize and de-energize
circuits in accordance with established safety practices.
• Trained in the proper care and use of protective equipment in accordance with established safety
practices.
Installation of ASD systems should conform to the 1999 National Electrical Code Article 110
(NEC) (Requirements For Electrical Installations), all regulations of the Occupational Safety and
Health Administration, and any other applicable national, regional, or industry codes and
standards.
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.
In the event of a power failure, the motor may restart after power is restored.
Retry or Reset settings may allow the motor to start unexpectedly. Warnings to this effect should be
clearly posted near the ASD and motor.
DO NOT install, operate, perform maintenance, or dispose of this equipment until you have read
and understood all of the following product warnings and user directions. Failure to do so may result
in equipment damage, operator injury, or loss of life.

Installation Precautions

• Use lockout/tagout procedures on the branch circuit disconnect before installing the ASD.
DANGER!
• Do Not mount the device in a location that would produce catastrophic results if it were to fall
from its mounting location (equipment damage or injury).
• Select a mounting location that is easily accessible by the user.
• Avoid installation in areas where vibration, heat, humidity, dust, metal particles, or high levels
of electrical noise (EMI) are present.
• Do not install the ASD where it may be exposed to flammable chemicals or gasses, water,
solvents, or other fluids.
• Always ground the unit to prevent electrical shock to personnel and to help reduce electrical
noise. The input, output, and control power cables are to be run separately and each shall have
its own ground cable.
Note:
• Ensure that the 3 phase input power is Not connected to the output of the ASD. This will destroy
the ASD and may cause injury to personnel.
• Do Not connect resistors across terminals PA – PC or PO – PC. This may cause a fire.
• Do not install the ASD if it is damaged or if it is missing any component(s).
• Turn the power on only after attaching the front cover.
