Installation and start-up steps
Read Safety instructions on page
Action
1 Check the delivery.
2 Ensure that the installation environment is suitable for ACS55.
3 Mount the unit.
4 Check applicability of the standard settings: Motor nominal frequency is 50 Hz; load is a pump or a fan; maximum output
frequency is 50 Hz. If the standard settings are not suitable, adjust the DIP switches.
5 Make sure the MOTOR I NOM potentiometer matches the rated current of the motor. It defines operation of the motor
thermal protection function.
6 Adjust the acceleration/deceleration time potentiometer ACC/DEC if necessary.
7 Connect the power supply cable and motor cables.
8 Connect the control wires.
9 Turn the power on. Green LED is illuminated. Note: Motor rotates if the start signal is active.
10 Set the speed reference and activate the start signal. The motor accelerates to the given speed reference.
Checking the insulation of the assembly
Do not make any voltage tolerance or insulation resistance tests (for example hi-pot or megger) on any part of the drive as testing can
damage the drive. Every drive has been tested for insulation between the main circuit and the chassis at the factory. Also, there are
voltage-limiting circuits inside the drive which cut down the testing voltage automatically.
