2.7 Configuration Interface
Configuration Interface Micro-B USB.
Note! WISE-221X modules can operate below 30% humidity. However, envi-
ronments with low relative humidity are prone to problems with electro-
static discharge. Therefore, you should ensure that you take adequate
precautions by using ground straps, anti-static floor coverings, or similar
equipment whenever you handle this equipment, especially in low-
humidity environments.
Note! To order an Advantech CT (Current Transformer), refer to section
2.11.Accessory: CT (Current Transformer).
If the user wants to choose a CT themselves, please make sure the ratio
of Np:Ns is above 1:3000, and the output range of the CT secondary
current value is between 0-100(mA).
Note! A USB cable is used for configuration purposes only.
