ACU-01B 3HNA024871-001 03 This chapter contains the mechanical and electrical installation procedure of the drive. WARNING! Before installing the ACH550, ensure the input power supply to the drive is off. For flange mounting (mounting the drive in a cooling air duct), see the appropriate Flange Mounting Instructions: Note: The ACH550 should only be mounted where all of the requirements defined in chapter Preparing for installation are met and the checklist has been completed.

Use the mounting template to mark the position of the mounting holes. 2. Drill the holes. 3. Insert the screws halfway into the holes. Note: Frame sizes R3 and R4 have four holes along the top. Use only two. If possible, use the two outside holes (to allow room to remove the fan for maintenance). 1 Installing the drive 39 ACH550-01 User's Manual Removing front cover (IP54) 1. Loosen the captive screws (the amount of screws depends on the size of the frame) around the edge of the cover. 2. Remove the cover. 1 2 40 Installing the drive ACH550-01 User's Manual Removing front cover (IP21) 1. Remove the control panel, if attached. 2. Loosen the captive screw at the top. 3.
