Safety 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 Categories

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.

Pollution degree description

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

Recycle precautions

Warning Some of the substances contained in this product may be harmful to the

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
