switch may be impaired.

Safety recommendations

WARNING!

When the ambient temperature exceeds 60°C (140°F), the outer surface temperature of the switch

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."

• Lastin

g 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.

Installation tools

No installation tools are provided with the switch. Prepare the following tools yourself as required:

• Flat-head screwdriver

• Phillips screwdriver

• ESD wrist strap

• Needle-nose pliers

• Diagonal pliers

• Cable crimping tool

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.
