Connecting voltage to the input terminals and auxiliary circuit
WARNING! Make sure that it is safe to apply voltage. Ensure that:
• nobody is working on the unit or circuits that are wired from outside into
the cabinets
• covers of motor terminal boxes are in place.
Close the circuit breakers which connect the voltage to essential
auxiliary devices, in other words: fans, boards, main breaker/contactor
control circuit, emergency stop circuit, 24 V DC power supply.
To locate the circuit breakers, see
the delivery-specific circuit diagrams
and the cubicle designations on
cabinet doors.
Close the cabinet doors.
Close the breaker of the supply transformer.
Drive with a grounding switch (option +F259)
: Open the grounding
switch.
Drive with main contactor (frames R7i+R7i and R8i+R8i
: Close the main
switch disconnector (Q1).
Drive with main breaker (frame 2xRi+2xR8i and bigger units):
Rack the
withdrawable breaker in.
Closing the main contactor/breaker
Turn the operating switch to position S for two seconds and then back to
position 1.
Checking the setting of the ground fault monitoring device
Option +Q954. See IRDH275
Operating Manual by Bender (code:
TGH1386) and the circuit diagrams
delivered with the drive
Check the settings of the ground fault monitoring device.
Supply unit control program set-up
Parameters of the IGBT supply unit control program need not be set
during the start-up procedure, or in normal use. In case the parameters
need to be changed, switch the control panel to communicate with the
supply unit as described in section Switching the control panel between
the supply and inverter units on page 114. Alternatively, connect a PC
equipped with a start-up and maintenance tool tool eg, DriveWindow, to
channel CH3 of the inverter unit’s RDCU.

Inverter unit control program set-up
Follow the instructions in the inverter unit firmware manual to start up the
inverter and set the parameters.

Units with sine filter (option +E206):
Set parameter 95.04 EX/SIN
REQUEST to SIN or EX&SIN.
Liquid cooling unit control program set-up
Units with optional liquid cooling unit (options +C139, +C140, +C141):
Check that parameter 33.01 CONTROL TYPE is set to LOCAL CTRL in
the liquid cooling unit control program.
Control panel of the liquid cooling
unit must be in remote control mode
Switch with the LOC/REM key of the
panel. ACS800-1007LC Liquid-
cooling Unit User's Manual
