Safety instructions

Important Information

Notice: Read these instructions carefully, and look at the equipment to

become familiar with the device before trying to install, operate, or maintain

it. The following special messages may appear throughout this

documentation or on the equipment to warn of potential hazards or to call

attention to information that clarifies or simplifies a procedure.

The addition of this symbol to a Danger or Warning safety label

indicates that an electrical hazard exists, which will result in

personal injury if the instructions are not followed.

This is the safety alert symbol. It is used to alert you to potential

personal injury hazards. Obey all safety messages that follow this

symbol to avoid possible injury or death.

Note: A note contains important information on the product, on how to

manage the product, or on the respective section of the documentation to

which your special attention is being drawn.

DANGER

DANGER indicates an imminently hazardous situation which, if not

avoided, will result in death or serious injury.

WARNING

WARNING indicates a potentially hazardous situation which, if not avoided,

can result in death or serious injury.

CAUTION

CAUTION indicates a potentially hazardous situation which, if not avoided,

can result in minor or moderate injury.

Certified usage

Please observe the following: The device may only be employed for the

purposes described in the catalog and technical description, and only in

conjunction with external devices and components recommended or

approved by the manufacturer. The product can only be operated

correctly and safely if it is transported, stored, installed and assembled

properly and correctly. Furthermore, it must be operated and serviced

carefully.

Supply voltage

For safety reasons the devices have been designed to operate at low

voltages. Thus, they may only be connected to the supply voltage

connections and to the signal contact with SELV circuits with the voltage

restrictions in accordance with IEC/EN 60950-1.

The supply voltage is electrically isolated from the housing.

Use undamaged parts.

Relevant for North America:

The device may only be connected to a supply voltage of class 2 that

fulfills the requirements of the National Electrical Code, Table 11(b). If

the voltage is being supplied redundantly (two different voltage

sources), the combined supply voltages must fulfill the requirements of

the National Electrical Code, Table 11(b).

Relevant for North America: For use in class 2 circuits.

Use 60/75 °C or 75 °C copper (Cu) wire only.

The device does not contain any service components. Internal fuses

are only triggered if there is a fault in the device. If the device is not

functioning correctly, or if it is damaged, switch off the supply voltage

and return the device to the plant for inspection.

Only switch on the supply voltage to the device if

the housing is closed,

the terminal blocks are wired up correctly and

the terminal blocks are connected.

Shielding ground

Note: The shield ground wire of the twisted pair lines is connected to the

front panel as a conductor.

Beware of possible short circuits when connecting a cable section with

conductive shielding braiding.

Hazardous Locations

Relevant for North America for devices certified for Hazardous Locations:

Power, input and output (I/O) wiring must be in accordance with Class I,

Division 2 wiring methods [Article 501-4(b) of the National Electrical

Code, NFPA 70] and in accordance with the authority having jurisdiction.



SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C AND D

HAZARDOUS LOCATIONS, OR NON-HAZARDOUS LOCATIONS

ONLY.

WARNING – EXPLOSION HAZARD – SUBSTITUTION OF ANY

COMPONENTS MAY IMPAIR SUITABLE FOR CLASS I, DIVISION 2.

WARNING – EXPLOSION HAZARD – DO NOT DISCONNECT

EQUIPMENT WHILE THE CIRCUIT IS LIVE OR UNLESS THE AREA IS

KNOWN TO BE FREE OF IGNITABLE CONCENTRATIONS.



The USB connector is for temporary connection only. Do not use,

connect, or disconnect unless area is known to be non-hazardous.

Connection or disconnection in an explosive atmosphere could result in

an explosion.



Peripheral equipment must be suitabel for the location it is used in. 

Use 60/75 °C or 75 °C copper (Cu) wire only.
