ACS550-U1-XXXX-X
The ACS550-U1 is a wall-mountable drive and is available from 0.75 to 100 HP in 230V and to 150 HP in 480V input voltages. The ACS550-U1 has six frame sizes (R1 to R6).  The ACS550-U1 is available in a standard UL Type 1 (NEMA 1) or optional UL Type 12 (NEMA 12)  enclosure and has a control panel for user interface, parameter adjustment and drive operation  mounted on the front of the drive. The front section of the ACS550-U1 contains the electronics,  power and control wire terminals. The rear section forms a cooling channel. The two section  construction allows the unit to be installed protruding through a wall, or through the rear wall of a  customer supplied enclosure using additional hardware, placing the rear section in a cooling air duct  to minimize the heat inside the cabinet. In standard installations, the drive is mounted directly onto  a wall and uses the provided conduit box. Conduit openings (knock-outs) are provided for bottom  and side conduit entry. For mounting inside a customer supplied cabinet, the conduit box may be  removed. R1 and R2 frames have built-in braking choppers.
