Safety

Warning! Only a competent electrician may install the ACS140.

Warning! Dangerous voltages are present when mains supply is

connected. Wait at least 5 minutes after disconnecting the supply before

removing the cover. Measure the voltage at DC terminals (U c+ , U c- ) before

servicing the unit (see G ).

Warning! Even when the motor is stopped there are dangerous

voltages present at Power Circuit terminals U1, V1, W1 (L,N) and U2, V2, W2

and U c+ , U c- .

Warning! Even when the ACS140 is powered down, there may be

dangerous external voltages at relay terminals RO1A, RO1B, RO2A, RO2B.

Warning! The ACS140 is not a field repairable unit. Never attempt to

repair a broken unit; contact the supplier for replacement of the unit.

Warning! The ACS140 will start up automatically after an input voltage

interruption if the external run command is on.

Warning! When the control terminals of two or more ACS100/140/

160 / 400 units are connected in parallel, the auxiliary voltage for these control

connections must be taken from a single source which can either be one of

the units or an external supply.

Warning! Altering the parameter settings or device configurations will

affect the function and performance of the ACS140. Check that these

changes do not cause any risk to persons or property.

Warning! There are several automatic reset functions in the ACS140.

If selected, they reset the unit and resume operation after a fault. These

functions should not be selected if other equipment is not compatible with this

kind of operation, or dangerous situations can be caused by such action.

Warning! The heat sink may reach a high temperature (see R ).

Note! For more technical information, contact the supplier.
