Clean the dust on the electronic overload relay timely. Conduct product
test and maintenance every half a year to ensure the smooth operation of
the product and the good contact of NO and NC contacts. Tighten the
terminal screws with specified torque and align the load protection
capability of the electronic overload relay according to commissioning
requirements. (See Figure 12)
Please be careful when handling and installing the thermal relay. It is
prohibited to move the product by crane with strong impact so that the
product will not be damaged and its protection characteristics will not
change.
