- Page 8 Mounting Warning! The unit will warm up to high temperature during normal operation. Ensure sufficient cooling air flow in all conditions: - Always install ACS50 so that cooling fins are vertically. - Leave sufficient space around the unit. Install the unit using the mounting clip on a 35 mm DIN rail or on a wall.

- Page 10 DIP switches DIP switches are used to adapt ACS50 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 ACS50 is powered.
- Page 11 RUN = Running. Contact is closed while running. Activates a living zero supervision for the analogue input. 4 mA (2 V) = ACS50 trips on a fault if the value drops OFFSET below the limit.
- Page 12 Calculate MOTOR I NOM with the equation below or pick a value from the MOTOR I NOM selection chart below. ACS50 estimates the temperature of the motor based on the measured output current and the defined motor nominal current. The drive trips if the motor overheats according to the estimation.
- Page 13 30 °C (86 °F). See also Additional cabling and EMC instructions. Earth leakage current of the ACS50 exceeds 3.5 mA AC / 10 mA DC. According to EN50178 ACS50 may only be used in permanent installation. Input fuse Recommended fuse types are UL class CC or T.
- Page 14 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 15 Additional cabling and EMC instructions Follow these instructions for trouble free operation and to ensure compatibility with 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 16 Speed controlling The analogue input gives the speed (frequency) reference for ACS50. 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.
