警告！即使电机停止，也会产生危险电压
在电源电路端子U1、V1、W1和U2、V2、V2和V2处，
并且根据帧大小，UDC+/BRK+和
UDC-/BRK-。
警告！输入功率不足时存在危险电压
有联系的。断开电源后，至少等待5分钟
在卸下盖子前几分钟。要检查，请测量零
直流端子处的电压，取决于机架
尺寸、UDC+/BRK+和UDC-/BRK-。
警告！即使当电源从输入端断开时
ACH550的端子可能存在危险电压（来自
外部电源）连接到继电器输出端
RO1…RO3，如果继电器扩展板包括在
安装，RO4…RO6。
警告！当两个或更多个控制端子驱动时
装置并联连接时，这些装置的辅助电压
控制连接必须来自单个源，该源：
可以是单元之一或外部电源。
警告！如果将驱动器安装在IT系统上（例如
电源系统未接地或高电阻接地[过电压]
30欧姆]电力系统）或配备有
剩余电流断路器），断开内部EMC
滤波器，否则系统将连接到地电位
通过EMC滤波电容器。这可能导致危险或危险
损坏驱动器。
如果将驱动器安装在角落接地TN系统上，
断开内部EMC滤波器的连接，否则系统将无法正常工作
通过EMC滤波电容器连接到地电位。
这将损坏驱动器。
注意：断开内部EMC滤波器会增加
传导发射，降低驱动器EMC兼容性

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. After disconnecting the supply, wait at least 5 minutes before removing the cover. To check, measure for zero voltage at the DC terminals, which are, depending on the frame size, UDC+/BRK+ and UDC-/BRK-. WARNING! Even when the power is switched off from the input terminals of the ACH550, there may be dangerous voltage (from external sources) on the terminals of the relay outputs RO1…RO3 and, if the relay extension board is included in the installation, RO4…RO6. WARNING! When the control terminals of two or more drive units are connected in parallel, the auxiliary voltage for these control connections must be taken from a single source which can either be one of the units or an external supply. WARNING! If you install the drive on an IT system (an ungrounded power system or a high-resistance-grounded [over 30 ohms] power system) or a power system equipped with residual current circuit breakers), disconnect the internal EMC filter, otherwise the system will be connected to ground potential through the EMC filter capacitors. This can cause danger or damage the drive. If you install the drive on a corner-grounded TN system, disconnect the internal EMC filter, otherwise the system will be connected to ground potential through the EMC filter capacitors. This will damage the drive. Note: Disconnecting the internal EMC filter increases the conducted emission and reduces the drive EMC compatibility considerably. 10 Contents of this manual ACH550-01 User's Manual For disconnecting the EMC filter, see Disconnecting the internal EMC filter on page 45. Maintenance WARNING! The ACH550 is not a field repairable unit. Never attempt to repair a malfunctioning unit; contact your local ABB representative for replacement. Control of the drive and motor WARNING! The ACH550 will start up automatically after an input voltage interruption if the external run command is on. WARNING! Do not control the motor with an AC contactor or disconnecting device (disconnecting means); use instead the control panel (operator keypad) start (HAND ), AUTO ) and stop (OFF ) keys or external commands (I/O or fieldbus). The maximum allowed number of charging cycles of the DC capacitors (i.e. power-ups by
