Rockwell Automation DC3N DC Drive User Guide, 1/4-2HP-115/230 VAC User Manual

ATTENTION: The control circuit is at line potential when the drive is
energized. Use a non-metallic screwdriver when making adjustments to
the circuit board potentiometers. Exercise extreme caution as
hazardous voltage exists. Failure to observe these precautions could
result in severe bodily injury of loss of life.

ATTENTION: Only qualified personnel familiar with the construction and
operation of this equipment and the hazards involved should install,
adjust, operate, and/or service this equipment. Read and understand
this instruction manual in its entirety before proceeding. Failure to
observe this precaution could result in severe bodily injury or loss of life.

ATTENTION: The user is responsible for conforming with all applicable
local and national codes. Failure to observe this precaution could result
in severe bodily injury or loss of life.

ATTENTION: It is possible for a drive to run at full speed as a result of a
component failure. Please ensure that a master switch has been placed
in the AC line to stop the drive in an emergency.

ATTENTION: Reduce the chance of an electrical fire, shock, or
explosion by proper grounding, over-current protection, thermal
protection and enclosure. Follow sound maintenance procedures.

ATTENTION: Starting and stopping with the inhibit terminal pins does
not disconnect AC power in the stop position. A hardwired AC power
disconnection switch must be mounted in close proximity to the
operator’s start/stop controls. This is required, as the DC3 drive does
not have an armature loop contactor. A single fault like a power device
short may cause motor rotation when in the stop mode. The user is
responsible for assuring safe conditions for operating personnel by
providing suitable guards, audio or visual alarms, or other devices.
