Safety
WARNING!
Obey the safety instructions during the start-up procedure. See
cooled multidrives cabinets and modules safety instructions (3AXD50000048633
[English]). If you ignore the safety instructions, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation or maintenance
work.
Checks/Settings with no voltage connected
Make sure that it is safe to start the work. Do the steps in section
tions (page 95).
Make sure that the disconnector of the supply transformer is locked into the open position and
that voltage cannot be connected to the drive accidentally.
Make sure that all external auxiliary circuits are de-energized and disconnected. See the start-
up instructions in the supply unit hardware manual.
Make sure that the supply unit is de-energized, and the drive system is isolated from the supply
network.
DC/DC converter with the DC switch-disconnector [Q11]: Make sure that the DC switch-discon-
nector [Q11] and the DC/DC converter charging switch [Q10] are open and locked.
Make sure that the energy storage disconnecting device (customer or system integrator-installed
device) is locked into the open position.
Make sure that the mechanical and electrical installation of the converter unit is completed and
inspected. Refer to the installation checklist.
Make sure that the drive is ready for the converter unit power 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 applicable
supply unit manual.
• The inverter units have been started up according to the instructions given in the hardware
manual and applicable firmware manual.
If the converter unit was stored for more than one year: Reform the electrolytic DC capacitors
in the DC bus of the drive. Refer to
Close the auxiliary voltage circuit breakers of the converter unit [F21, F22]. Close also other circuit
breakers of the converter auxiliary circuits: cabinet fans [F115] and BAMU voltage/current
measurement [F7] if present and the auxiliary voltage switch of the drive supply unit.
Starting and checking the cooling system
Fill up and bleed the internal cooling circuit. Start the cooling unit up. See
the internal cooling circuit (page
Check the cooling system for leaks. Make sure that cooling circuit joints at the shipping split
joining cubicles are tight and that all drain valves have been closed.
Make sure that the coolant can flow freely in all cubicles.
Close the 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 disconnector
of the supply transformer.
