Installing Regulator Board
P/N 0-56921-6xx in
7.5 to 10 HP @ 460 VAC Drives
Use the procedure in this chapter to replace the Regulator board (P/N 0-56921-6xx) in
7.5 to 10HP@ 460VAC GV3000/SE drives with model numbers 7V41xx, 7V42xx,
10V41xx, and 10V42xx.
If the drive is panel-mounted, this procedure will be easier to perform if the drive is
removed from the panel.
Some steps are only required if an option board, such as the AutoMax Network option
board, is installed. These steps are preceded by the text “Option board only.”
Unless otherwise indicated, keep all hardware that is removed. You will need it for
reassembly. This includes option boards, screws, lock washers, and rivets.
Refer to figure 3.4 as you perform the procedure.
Important: Read and understand the warning labels on the outside of the drive
before proceeding.

ATTENTION: Only qualified electrical 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 manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: The drive is at line voltage when connected to incoming
AC power. Disconnect, lock out, and tag all incoming power to the drive
before performing the following procedure. Failure to observe this
precaution could result in severe bodily injury or loss of life.
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power, wait five
minutes for the DC bus capacitors to discharge and then check the
voltage with a voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of life.
