Single-phase EMI filter CW4EL2, 115/250VAC

The CW4EL2 single-phase mains EMI filter is designed to suppress high-frequency interference (differential and common mode) on AC power lines. It is used at the input of the device between the power supply network and the load, where it contributes to reducing the propagation of interference into the network and increasing the device's immunity to interference from the environment.

Installation and operating instructions

• Install the filter as close as possible to the point where the power enters the device.
• Observe the orientation of the input and output: connect the network to the LINE terminals, the load to the LOAD terminals.
• Connect the protective conductor (PE/ground) to the appropriate ground terminal and ensure good grounding of the metal structure.
• To achieve effective filtration, route input and output wires separately and minimize their overlap.

Safety notice

• The device is designed to operate with a mains voltage of up to 250VAC. Incorrect installation may result in electric shock or damage to the device.
• Installation and connection may only be carried out by a qualified person with the power supply disconnected.
• Always ensure proper grounding and comply with applicable standards and regulations for installation in switchboards.
