might exceed 70°C (158°F). You must install the switch in a restricted access area. To avoid burns,
take protective measures when working with the switch.
To avoid bodily injury or damage to the switch, read the following safety recommendations carefully
before working with the switch. Note that the recommendations do not cover every possible
hazardous condition.
•Before cleaning the switch, remove all power cords from the switch. Do not clean the switch
with wet cloth or liquid.
•Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•Do not place the switch on an unstable case or desk.
•Ensure adequate ventilation for the switch and keep the protective vents of the switch
unblocked.
•Make sure the power source voltage meets the requirements of the switch.
•To avoid electrical shocks, do not open the chassis while the switch is operating. As a best
practice, do not open the chassis even if the switch is powered off.
•When installing the switch, always wear an ESD wrist strap. Make sure the wrist strap makes
good skin contact and is reliably grounded.
NOTE:
The switch is a class A device and might cause radio interference in a residential area. Take
adequate measures as required.
Examining the installation site
The switch must be installed on a DIN rail. Make sure the DIN rail is strong enough to support the
switch and its accessories.
To ensure correct operation and prolong service life of your switch, make sure the installation site
has a good ventilation system and meets the following requirements.

1-2
Humidity
To ensure correct operation and long service life of your switch, maintain the ambient humidity at the
acceptable ranges. For the humidity requirements of the switch, see "Technical specifications."
•Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•A conduction pattern of capacitance coupling.
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
Laser safety
WARNING!
The switch is a Class 1 laser device. Disconnected optical fibers or transceiver modules might emit
invisible laser light. Do not stare into beams or view directly with optical instruments when the switch
is operating.

Connecting the grounding cable
WARNING!
Correctly connecting the grounding cable for the switch is crucial to lightning protection and EMI
protection.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this
chassis ground to the earth so the faradism and leakage electricity can be safely released to the
earth to minimize EMI susceptibility of the switch.
To connect the grounding cable for the switch:
1. Remove the grounding screw from the switch.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
screw hole. Fasten the screw.
3. Connect the other end of the grounding cable to the grounding system.
