2.1 Installation Precautions
• Use lockout/tagout procedures on the branch circuit disconnect before installing
the option into the ASD.
• 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 or option where it may be exposed to flammable
chemicals or gasses, water, solvents, or other fluids.
• Where applicable, always ground the option appropriately to prevent electrical
shock to personnel and to help reduce electrical noise. The ASD’s input, output,
and control power cables are to be run separately from the option’s associated
cables.
Note: Conduit is not an acceptable ground.
• Turn the power on only after attaching the front cover.
• Follow all warnings and precautions and do not exceed equipment ratings.
• The ASD maintains a residual charge for a while after turning the ASD off. Wait
at least ten minutes before servicing the ASD after turning the ASD power off.
Ensure that the Charge LED is off prior to beginning installation.
• For further drive-specific precaution, safety and installation information, please
refer to the G7 Adjustable Speed Drive Operation Manual supplied with your
