Safety
Warning! Only a competent electrician may install the ACS 160.
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
DC voltage at terminals R+ and X4-2 before servicing the unit. (See H.)
Warning! Even when the motor is stopped there are dangerous voltages present at Power
Circuit terminals U1, V1, W1 and U2, V2, W2.
Warning! Even when the ACS 160 is powered down, there may be dangerous external
voltages at relay terminals 16 (RO1A), 17 (RO1B), 18 (RO2A), 19 (RO2B).
Warning! Never attempt to repair a broken unit; contact the supplier.
Warning! The ACS 160 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 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! The ACS 160 must not be powered up more than 3 times in 5 minutes to avoid
overheating the charging resistors.
Warning! The heatsink may reach a high temperature (100 °C / 212 °F).
Note! For more technical information, contact your local ABB supplier.
