Safety instructions
Read the following instructions carefully before proceeding with the
installation.
Warning! Dangerous voltage!
Only a competent electrician may install ACS55.
Never work on the drive, the motor cable or the motor when main
power is applied. After switching off the input power, always wait at
least for 5 minutes to let the intermediate circuit capacitors
discharge before you start working on the drive.
Warning! If the heat sink is not earthed properly, you can get an
electric shock if you touch the heat sink.
Note: DIP switches are at a dangerous voltage.
Note: Even when the motor is stopped, dangerous voltages are
present at power circuit terminals L/R, N/S, T1/U, T2/V and T3/W.
Note: Even when the unit is powered down, there may be
dangerous external voltages connected from outside to the relay
output terminals.
Warning! Hot surfaces!
During operation, the cooling element may reach high temperature
(>80°C). Make sure to follow the installation instructions.
General safety instructions
ACS55 starts the motor automatically after a supply break if the
external start signal is on.
Never attempt to repair a broken unit. ACS55 is not a field
repairable unit. Contact the supplier for replacement.
Install ACS55 in a locked or tool-openable space.
Do not connect input power to the unit more than once every three
minutes.
Altering the DIP switches will affect the function and performance
of ACS55. Check that the changes will not cause any risk to
persons or property.

1 Check the delivery. 7
2 Ensure that the installation environment is suitable for ACS55. 10
3 Mount the unit. 12 -
13
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. 16
7 Connect the power supply cable and motor cables. 17
8 Connect the control wires. 18
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. 20

Environmental limits
1) When operating the drive in subzero temperatures, keep the input power connected. Install the drive inside an enclosure. Ensure that
heat generated by the drive will be properly dissipated.
Degree of protection of ACS55 is IP20.

Mounting
Warning! The unit will warm up to high temperature during normal operation. Ensure sufficient cooling air flow in all conditions:
- Always install ACS55 so that cooling fans are vertical.
- Leave sufficient space around frame A and B units. Frame C and D units are fan cooled, so they can be installed side by side without
extra space between them.
Install the unit using the mounting clip on a 35 mm DIN rail or on a wall.
Mounting on DIN rail
"Click" ACS55 to the rail. Press the
lever on top of the mounting clip to
detach.
Mounting on wall
Install the unit onto the wall through
the mounting clip. Use M4 screws.
Clearance distances
Always leave sufficient space around the unit to ensure
proper cooling.
