Security Requirements

Warning

Only the voltage within the specified range can be connected.

Voltage exceeding the specified range may cause damage to the

device, and even present a negative impact on personal safety. Check

the product specification for detailed reference to the range of

voltages that can be connected by each port.

Warning

Do not attempt to operate the device in other ways that are not

mentioned in this document. Incorrect use of the device may be

dangerous. In the event of device damage, the internal security

protection mechanism will also be affected.

Warning

Do not attempt to replace device components or change devices in

other ways that are not mentioned in this document. Do not repair

the device yourself in the event of a product failure.

Warning

Do not use the device in an environment where an explosion may

occur or where flammable flue or gas is present. If you must use the

device in this kind of environment, please fit it into a proper case.

Warning

While the device is running, all chassis covers and fill panels need to

be closed.

Warning

For equipment with exhaust vents, do not insert foreign objects into

the vents or block air circulation in the vents.

Measurement Category

Warning

For use in measurement category I (CAT I) only. Do not use in

measurement category II/III/IV. Use this device to connect signals or

make measurements.

Measurement categories Note

Measurement categories I (CAT I) means that measurements are made on a circuit that is not

directly connected to the main power supply. For example, a circuit that is not exported from

the main power supply, especially a circuit that is exported from a protected (internal) primary

power supply, is measured. In the latter case, the instantaneous stress will change. Therefore,

the user should be aware of the instantaneous affordability of the device.

Measurement categories II (CAT II) means that measurements are made on a circuit that is

directly connected to a low-voltage device. For example, a measurement on household

appliances, portable tools and similar equipment.

Measurement categories III (CAT III) means that measurements are made in construction

equipment. For example, a measurement on the distribution boards, circuit breakers, wiring

(including cables, Busbars, junction boxes, switches, sockets) in fixed equipment and

equipment for industrial use and certain other equipment (for example, fixed motors that are

permanently connected to fixtures).

Measurement categories IV (CAT IV) means that measurements are made on the source of

low-voltage equipment. For example, a measurement on a meter, a major overcurrent

protection device, and a pulse control unit.

Environment

Pollution level explanation

Pollution degree 1: No pollution, or only dry non-conductive pollution. This pollution level has no

effect. For example: a clean room or an air-conditioned office environment.

Pollution degree 2: Generally, only dry non-conductive pollution occurs. Temporary conduction

can sometimes occur due to condensation. For example: General indoor environment.

Pollution degree 3: Conductive pollution occurs, or dry non-conductive pollution becomes

conductive due to condensation. For example, an outdoor sheltered environment.

Pollution degree 4: Permanent conductive pollution caused by conductive dust, rain or snow. For

example: outdoor places.

environment or human health. In order to avoid releasing harmful

substances into the environment or endangering human health, it is

recommended that appropriate methods be used to recover this product

to ensure that most materials can be properly reused or recycled. For
