- Page 4 Warnings CAUTION Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed E7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.
- Page 5 Safety Precautions and Instructions General Please read these safety precautions and instructions for use thoroughly before installing and oper- ating this inverter. Also read all of the warning signs on the inverter and ensure they are never dam- aged or removed. Live and hot inverter components may be accessible during operation.
- Page 6 Laying Cables Measures Against Line-Borne Interference: The Varispeed E7 IP54 is equipped with an internal EMC filter. To ensure the best performance of the filter ensure to follow the mounting instructions regarding the connection of the shieldings. Use a motor cable with well-grounded shield.
