Tasks
Powering up the auxiliary circuit of the supply unit
Make sure that it is safe to connect voltage. Make sure that:
•nobody is working on the unit or circuits that are wired from outside into the cabinets
•covers of the motor terminal boxes are on.
Supply unit with the voltage meters on door ([F5], G334): Close the circuit breaker for the
meters.
Close the circuit breakers supplying the auxiliary circuits [F22,..., F26].
Close the cabinet doors.
Close the disconnector and breaker of the supply transformer. The drive input power terminals are
energized.
Switch the auxiliary voltage switch [Q21] on. The drive auxiliary circuit is energized.
Supply unit with the grounding switch ([Q9], F259): Open the grounding switch.
WARNING!
Do not use excessive force. If the unit is equipped with a grounding switch [Q9], electromag-
netic interlocking is also used. You cannot switch the main switch-disconnector [Q1] on before
its lock release relay [K1] is energized, that is:
•the main input terminals [L1, L2 and L3] are powered, and
•auxiliary voltage switch [Q21] is switched on, and
•circuit breakers [F22 and F23] in between the relay [K1] and auxiliary voltage switch [Q21]
are switched on.
Setting up the supply unit parameters
Check the correct voltage range, parameter 195.01 Supply voltage .
If your supply unit consists of more than one module, parameters 195.30 Parallel type filter and 195.31
Parallel connection rating id need to be set. First, select the correct voltage range with parameter
195.30 Parallel type filter . Then, select the correct supply unit type with parameter 195.31 Parallel
connection rating id .

If you need more information on the use of the control panel, see ACS-AP-x assistant control panels
user's manual (3AUA0000085685 [English]).
Switch the control panel to the remote mode (Loc/Rem key) to enable control of the supply unit with
the operating switch [S21].
Drives with a fieldbus adapter (optional): Set the fieldbus parameters. Activate the fieldbus adapter
module in the control program. See the user’s manual of the fieldbus adapter module, and

IGBT supply control program firmware manual (3AUA0000131562 [English]).
Powering up the main circuit of the drive
Close the main disconnecting device:
Supply unit with main switch-disconnector ([Q1], F253): Close the main switch-disconnector
[Q1].
Supply unit with main breaker ([Q1], F255): Rack in the main breaker [Q1].
Note: The grounding switch ([Q9], F259) must be switched off.
WARNING!
Do not use excessive force. There is electromagnetic interlocking in use. See section Electro-
magnetic interlocking (page 70) .
Switch the charging circuit switch fuse [Q3] on.
