Action
Make sure that it is safe to connect voltage:
• nobody is working on the unit or circuits that are wired from outside into the cabinets
• covers of the motor terminal boxes are on
• cabinet doors are closed
• the disconnecting device [Q1] is open.
Drive with the earthing/grounding switch [Q9] (F259): Open the earthing/grounding switch.
Close the auxiliary voltage switch [Q21].
￭ Setting the supply unit parameters
Action
If the supply unit includes one supply module:
• Check the correct voltage ranges by parameter 195.01 Supply voltage .
• Reboot the control unit by parameter 196.08 Control board boot .
If the supply unit includes more than one supply module: Make sure that the value of parameter 195.31
Parallel connection rating id corresponds to the actual number of parallel-connected diode supply
modules:
• Select the correct voltage range with parameter 195.30 Parallel type filter .
• Select the correct supply unit type with parameter 195.31 Parallel connection rating id .
• Reboot the control unit by parameter 196.08 Control board boot .
• Check the correct voltage range, parameter 195.01 Supply voltage .
• Reboot the control unit by parameter 196.08 Control board boot .
If you need more information on the use of the control panel, see ACX-AP-x assistant control panels
user's manual (3AUA0000085685 [English]).
￭ Powering up the drive
Action
Close the disconnecting device of the supply unit.
Drive with main breaker [Q1] (F255): Unlock the withdrawn breaker, and crank it in.
WARNING!
Never use the start button of the air circuit breaker to close it. Start button bypasses normal
start-up procedure and may damage the module.
Make sure that the control panel [A59] is in the remote mode (Loc/Rem key of the panel).
Switch the Run enable and Start signals at digital input DI2 on (1) to start the operation of the supply
unit.
Turn the operating switch [S21] on the cabinet door to ENABLE/RUN (1) position.
Run enable starts the supply unit power up sequence. After the program has stepped through it (ap-
proximately 3 seconds), the drive DC link is charged, the main breaker is closed and the supply unit
is in operation and ready to the supply inverters.
Turn the operating switch [S21] to on (1) position to activate the Run enable signal and to close the
main breaker [Q1].
