VDI7561B
此驱动器的保护接地导体中可以引入直流电。如果是剩余电流装置
（RCD/GFCI）或剩余电流监测器（RCM）用于防止直接或间接接触，
必须使用以下特定类型：
剩余电流装置使用的其他条件：
 在通电时，驱动器的泄漏电流增大。使用剩余电流
具有响应延迟的装置（RCD/GFCI）或剩余电流监测器（RCM）。
 必须过滤高频电流。
警告

不遵守这些说明可能导致死亡、重伤或设备损坏。

Direct current can be introduced in the protective ground conductor of this drive. If a residual current device (RCD / GFCI) or a residual current monitor (RCM) is used for protection against direct or indirect contact, the following specific types must be used: Further conditions for use of a residual current device:  The drive has an increased leakage current at the moment power is applied. Use a residual current device (RCD / GFCI) or a residual current monitor (RCM) with a response delay.  High-frequency currents must be filtered. WARNING DIRECT CURRENT CAN BE INTRODUCED INTO THE PROTECTIVE GROUND CONDUCTOR  Use a Type A Residual Current Device (RCD / GFCI) or a Residual Current Monitor (RCM) for singlephase drives connected to a phase and to the neutral conductor.  Use a Type B Residual Current Device (RCD / GFCI) or a Residual Current Monitor (RCM) that has approval for use with frequency inverters and is sensitive to all types of current for three-phase devices and for single-phase devices not connected to a phase and the neutral conductor. Failure to follow these instructions can result in death, serious injury, or equipment damage.
