[BEMF General Information]

1. Applications

BEMF products are designed and manufactur ed for installation in commer cial and industrial machinery and equipment. They are used in the following equipments and facilities:

Solar inv erter, PCS, ESS, EV

Industrial UPS

Telecommunication equipment

FA equipment

Commercial automatic washing machine

CNC machine

Inverter, Converter

Elevator

Servo motor driv er

Military

Etc.

2. Before Installation

1) Before installation and use of the pr oduct, be sure to check the contents of the catalog and instruction manual.
2) In or der to av oid the risk of o verloading, please select BEMF products with capacit y of about 110% or more of the equipment or facilit y power to use, or oper ate the equipment within about 80% of BEMF r ated capacity.
3) Make sure that the input power is cut off, and install this product af ter avoiding the envir onment where there is a lot of water, moisture, dust and corr osive gas.
4) When connecting the power supply and the product, if the terminal is damaged due to e xcessive torque, or if it is loosely coupled, ther e may be a fire due to overload.
5) Do not modify, disassemble, or disassemble the product arbitrarily to maintain safety and performance of the product and system.

3. Reference

When using equipment, the noise that affects is gener ated in various forms such as switching noise, surge, harmonics, electromagnetic pulse and electr omagnetic field. It is not effective for all types of noise with one EMI filter. In each case, you must use suitable protective measures.

[Installation of EMI Filter]

1. How to install

1) The ground wire should be short and thick wire.
2) Separate the input and output wires of the EMI filter. (W1, W2)
3) Be sure to disconnect the low voltage / DC communication line and the power line. (W3, W4)
4) Install near power input.
5) If the case is grounded, remove the paint or foreign matter from the installation part and fix it tightly.
6) Do not apply excessive torque when connecting EMI filter terminal (Torque Table)
7) Use a socket wrench or spanner that meets specifications when fastening bolts.

2. Installation Precautions

1) Do not use general LC filter at the end of inverter or servo driver. There may be abnormal heat due to harmonics and system malfunction.
2) Connect the input and output of the three-phase EMI filter so that they do not change each other (L1 - L1' / L2 - L2' / L3 - L3')
