  • Page 7: Installation And Start-Up Steps

    Action Check the delivery. Ensure that the installation environment is suitable for ACS55. Mount the unit. 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.
  • Page 8: Environmental Limits

    Not allowed Not allowed 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.

  • Page 10 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.
  • Page 11 Attaching and detaching the wall mounting clip The unit can be mounted either with the wide or the narrow side against the wall. Install the mounting clip on the desired side. See instructions below for frames A and B. Detach the mounting clip of frames C and D by pulling downward and attach it by pushing upward.
  • Page 12: Dip Switches

    DIP switches DIP switches are used to adapt ACS55 to the motor and the application. Warning! The DIP switch is at a dangerous voltage (200 V). Turn off power and wait for 5 minutes before adjusting the switches. Keep the protective cover closed when ACS55 is powered.
  • Page 13 RUN = Running. Contact is closed while running. Activates a living zero supervision for the analogue input. 4 mA (2 V) = ACS55 trips on a fault if the value drops OFFSET below the limit.
  • Page 14: Control Potentiometers

    Calculate MOTOR I NOM with the equation below or pick a value from the MOTOR I NOM selection chart below. ACS55 estimates the temperature of the motor based on the measured output current and the defined motor nominal current. The drive trips if the estimated temperature implies motor overheating.

    30°C (86°F). See also Additional cabling and EMC instructions on page 19. Earth leakage current of the ACS55 can exceed 3.5 mA AC / 10 mA DC. According to EN50178, ACS55 may only be used in permanent installation. Input fuse...
  • Page 16: Connecting Control Wires

    Connecting control wires Control terminals Use multi-strand 0.5...1.5 mm wire (AWG22 - AWG16). Internal (1) or external (2) power supply can be used for the digital Name Description inputs. Analogue control voltage is 0…10 VDC as default. (The AI jumper must be in voltage ("U") position). Common for digital or analogue inputs Common for digital or analogue input Analogue input: Speed (frequency) reference.
  • Page 17: Additional Cabling And Emc Instructions

    Additional cabling and EMC instructions Follow these instructions for trouble free operation and to ensure compatibility with the European EMC directive. Motor cable The motor cable must be a symmetrical three conductor cable with a concentric PE conductor or a four conductor cable with a concentric shield.
  • Page 18: Speed Controlling

    Speed controlling The analogue input gives the speed (frequency) reference for ACS55. The correspondence between the analogue input and the reference depends on the settings of the DIP switches as shown below. Output frequency follows the reference changes as defined by the ACC/DEC potentiometer.

    Motor overload (I t overload): 1) Check the load, and verify that the motor size is suitable for ACS55. 2) Verify that setting of MOTOR I NOM potentiometer is correct. Output short circuit: Switch off the power and check the motor Inverter overload or excessive internal temperature: 1) Load windings and motor cable.
