Safety issues
• When using improperly, it may cause damage to the controller or system;
• Please don’t make withstand voltage testing for the controller;
• Never connect AC power to output U, V, W terminals;
• If the internal components of the controller were influenced or damaged by static, please do not to touch;
• The motor, controller and power specifications should be matching, otherwise it could cause abnormal operation even burn out the device;
• If the controller appears serious vibration, noise, heat or peculiar smell in the first operation, please cut off the power immediately and contact suppliers or service center later;
• Please don’t expose the controller in the environment with direct sunlight, rain, frost or snow in case of deformation or damage.
Cautions
• Please don’t dismantle, change the product, or may cause electric shock, fire hazard and personal injury;
• Please don’t open the cover during the running of controller;
• Please don’t put wire, bar of metal, filaments etc. into the controller so as not to cause a short circuit or get an electric shock;
• Please don’t splash water or other liquid over the controller;
• Layout operations should be carried out by a qualified electrical professional, and construct in accordance with the electrical code.
