The lightning preventing wires are not provided and should be purchased by users as required. For the
usage of lightning preventing wires, refer to their manuals.
EMI Consideration
All kinds of interference, from inside or outside of the device or application system, create impacts on the device by
transmission of capacity coupling, inductance coupling and electromagnetic waves.
Electromagnetic interference can be divided into two categories by transmission types, namely i.e. radiated interference
and conducted interference.
Power, normally RF power, transmitted from a device through space to a sensor is called radiated interference. The
origin of the interference source can either be part of or a unit separated electrically from the interfered system.
Conducted interference is transmitted through magnetic wires or signal cables from the source origin to sensors.
Generally, conducted interference affects the power supply of a device and can be controlled by a wave filter. Given
that radiated interference can interrupt any signal paths of the device, it is difficult to shield the device from such
interference.

The power supplying system should be effectively protected by an electricity shield.

Grounding devices of power supply power supplying equipment and anti-lightening grounding devices should be
used in the working area of switch and should be deployed far away from switch.

The switch should be placed far away from high-power radio transmitting stations, radar stations and
high-frequency and large-current devices.

Electrostatic shielding methods should be applied.
Precautions for Fiber Connections
Before you connect the fibers, check that the optical connector type and fiber type match the optical interface type used.
In addition, pay attention to the Tx and Rx directions of the fiber. The Tx end of this device should be connected to the
Rx end of the peer device, and the Rx end of this device to the Tx end of the peer device.
