    The Enclosed ACS255s can be installed side-by-side with their heatsink flanges touching. This gives adequate ventilation space between drives.  If the ACS255 is to be installed above another drive or any other heat- producing device, the minimum vertical spacing (X) is 150mm (5.9 inches) above and below.

  • Page 18: Gland Plate And Lock Out

    4.6. Gland Plate and Lock Out The use of a suitable gland system is required to maintain the appropriate IP / Nema rating. The gland plate has pre moulded cable entry holes for power and motor connections suitable for use with glands as shown in the following table. Where additional holes are required, these can be drilled to suitable size.

  • Page 19: Power Wiring

    A hazard of personal injury and/or equipment damage exists if codes are ignored during installation. This ACS255 contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage levels.

  • Page 20: Wiring Precautions

    5.1.6. Ground Fault Monitoring As with all inverters, a leakage current to earth can exist. The ACS255 is designed to produce the minimum possible leakage current while complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the earth connections used and the type of RFI filter installed.
