Appendix I Magnetic Ring Filter Instruction
To reduce electromagnetic interference that power supply generates, it is necessary to install a magnetic ring filter with the power cable.
To install a magnetic ring filter with power supply:
Step 1:
Open the magnetic ring filter and lead the power cable through.
Step 2:
Wire the power cable on the magnetic ring filter 3 rounds or more (Make sure the filter can be well closed).
Step 3:
Close the magnetic ring filter.
Notice:
The magnetic ring filter should be installed no more than 50 mm away from the power output connector. As shown in Figure 3, the
cable length from A to B should be 50mm at most.
