Start-up procedure

Action
Checks/Settings with no voltage connected
Ensure that the disconnector of the supply transformer is locked to the off (0) position, ie. no voltage
is, and cannot be connected to the drive inadvertently.
Make sure that the main disconnecting device of the supply unit is open and locked:
• Drives with a main switch-disconnector ([Q1,], option +F253): Open the main switch-disconnector of
the drive.
• Drives with a main breaker ([Q1], option +F255): Crank the main breaker to DISCONNECTED position.
Drive with the grounding switch ([Q9] , option +F259): Close the grounding switch.
WARNING! Do not use excessive force. Check the inter-lockings if you cannot turn the switch.
See the delivery-specific circuit diagrams.
Make sure that the charging disconnector [Q3] and the DC switch-disconnector for line-up charging
[Q40] (if present) are open.
Open the auxiliary voltage switch [Q21].
Check the mechanical and electrical installation. See chapter
Check the settings of breakers/switches in the auxiliary circuits. See the delivery-specific circuit diagrams.
Disconnect any unfinished or uninspected auxiliary voltage (115/230 V AC) cables that lead from the
terminal blocks to the outside of the equipment.
Drives with ground fault monitoring for IT (ungrounded) systems (option +Q954): Adjust the settings of
the ground fault monitor to suit the installation. See the circuit diagrams of the delivery and IRDH275B
Ground Fault Monitor Operating Manual by Bender (code: TGH1386en).
Powering up the auxiliary circuit
Make sure that it is safe to connect voltage. Ensure that
• nobody is working on the unit or circuits that have been wired from outside into the cabinet
• the cover of the motor terminal box is in place.
Drives with a voltmeter ([P5], option +G334): Make sure that the circuit breaker of the measuring circuit
(F5.1) is closed.
Close the circuit breakers and/or fuse disconnectors supplying the auxiliary voltage circuits.
Close the cabinet doors.
Close the main breaker of the supply transformer.
Close the auxiliary voltage switch [Q21].
Also switch on the voltage to any other externally-supplied options (such as the cooling fan supply,
lighting, heating).
Starting and checking the cooling system
Fill up and bleed the internal cooling circuit. Start the cooling unit up. See
internal cooling circuit (page
If the drive is equipped with a cooling unit (ACS880-1007LC): Start up and power up the cooling unit.
See ACS880-1007LC liquid cooling unit user's manual (3AXD50000129607 [English]) and the delivery-
specific circuit diagrams.
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. Make sure that drive system cools down. See
ACS880-1007LC liquid cooling unit user's manual (3AXD50000129607 [English]).
Install all shrouds (if removed) and close the cabinet doors.
