In the dirty or risky area, the meter should be installed in a protection box. Meter should be fixed on a firm, fire-resistant and stable support.
transportation(damage of meter cover, hanger, seal, and LCD display, etc) As the internal part of the electrical meter is composed by the delicate electronic components, the meter should be carefully protected during the installation in order to avoid any damage. Make sure that the power is cut off before the meter installation, otherwise it will cause a threat to life. The fuse should be disconnected and put it in a safe place to avoid the accidental power-on.
terminal box wiring holes, ensure the safety and insulation effect. 6、 When using a small sectional cable, such as 4mm squared, the cable must be placed in the medium to ensure that the screw is well tightened without deviation. 7、 The cables should be connected correctly according to the wiring diagram and the terminals should be tightened during the installation in order to avoid any damage caused by bad connection.
10、 Close the terminal cover, and sealed it. Please to ensure that the terminal cover is closed tightly, otherwise it will cause the meter relay cut off due to terminal cover open(If required, can add this relay off through terminal cover open). 8.1 Testing after installation Insert the fuse, connect to the grid Check the meter display, is there any malfunction indication, phase inverse, cover open, or strong magnetic field, no current indictor. 8.
8、 If necessary, please replace a new meter. If a new meter cannot be installed for the moment, please envelop the voltage and current connection cables in insulating material and avoid exposing any bare metal part, otherwise it will pose a threat to life. 9.How to use： Power on the meter, the module will be in the working , when the module receives the user's command information, the module will return the corresponding information to the user device.
FCC Statement： Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference,and (2) this device must accept any interference received, including interference that may cause undesired operation.
