the drive.
Checks/Settings with no voltage connected
Make sure that it is safe to start the work. Obey the drive work instructions for switching off and
disconnecting in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]).
Make sure that the disconnector of the supply transformer is locked to the off (0) position, that
means no voltage is, or cannot be connected to drive inadvertently.
Make sure that all external auxiliary circuits are switched off and disconnected. See the start-up
instructions in the supply unit hardware manual.
Make sure that the drive main disconnecting device is open and locked:
Drives with a main switch/disconnector [Q1]: Open and lock the main switch/disconnector of the
drive.
Drives with a main breaker [Q1]: Crank the main breaker to the DISCONNECTED position.
DC/DC converter with the DC switch/disconnector [Q11]:
Make sure that the DC switch/disconnector [Q11] is open and locked.
Make sure that the energy storage disconnector is open and locked to open position (customer-
installed device).
Make sure that the mechanical and electrical installation of the converter unit has been inspected
and is OK. See chapter Installation checklist .
Make sure that the drive is ready for the converter unit start-up:
• The supply and inverter units have been installed according to the instructions given in their
hardware manuals.
• The supply unit has been started up according to the instructions given in the appropriate supply
unit manual.
• The inverter units have been started up according to the instructions given in the hardware
manual and appropriate firmware manual.
For the supply and inverter unit hardware manuals, see List of related manuals the inside of the front
cover.
Note: If the drive has been stored over one year: Reform the electrolytic DC capacitors in the DC
bus of the drive. See the separate reforming instructions (available in the Internet or from your local
ABB representative).
Make sure that the DC/DC converter is equipped with a control panel, or preferably, you have a PC
with the Drive composer tool connected to the DC/DC converter control unit [A41].
Close the auxiliary voltage circuit breakers of the converter unit [F21.1, F26.1]. Close also other
circuit breakers in between the converter control unit [A41] and the auxiliary voltage switch [Q21] of
the drive supply unit.
Close all cabinet doors.
Connecting voltage to the drive and converter control unit
Connect main AC voltage to the input terminals of the drive supply unit. (Close the main breaker of
the supply transformer.)
