This manual covers ACH550-01 drives. For ACH550-UH drive data and instructions, please refer to ACH550-UH HVAC Drives User’s Manual (3AUA0000004092 [English]). The manual is compatible with the ACH550-01 drive firmware version 3.14e or later. See parameter 3301 on page FIRMWARE 256.
ACH550-01 User's Manual Use of warnings and notes There are two types of safety instructions throughout this manual: • Warnings caution you about conditions which can result in serious injury or death and/or damage to the equipment. They also tell you how to avoid the danger.
Page 14
ACH550-01 User's Manual WARNING! Even when the motor is stopped, dangerous voltage is present at the power circuit terminals U1, V1, W1 and U2, V2, W2, and, depending on the frame size, UDC+/BRK+ and UDC-/BRK-. WARNING! Dangerous voltage is present when input power is connected.
