Safety instructions

This documentation contains instructions which must be observed to ensureyour own personal safety and to avoid damage to devices and machinery.

 Important Information

Notice: Read these instructions carefully, and look at the equipment tobecome familiar with the device before trying to install, operate, ormaintain it. The following special messages may appear throughout thisdocumentation or on the equipment to warn of potential hazards or to callattention to information that clarifies or simplifies a procedure.

The addition of this symbol to a Danger or Warning safety labelindicates that an electrical hazard exists, which will result inpersonal injury if the instructions are not followed.This is the safety alert symbol. It is used to alert you to potentialpersonal injury hazards. Obey all safety messages that followthis symbol to avoid possible injury or death.

 Certified usage

The device may only be employed for the purposes described in thecatalog and technical description, and only in conjunction with external devices and components recommended orapproved 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.

Note: Only the PoE media module MM22-T1T1T1T1 has an externalpower supply.

 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.Only use copper wire/conductors of class 1, 75 °C (167 °F).

 For using the device in areas with a risk of gas explosion according to

directive 94/9/EC (ATEX):

 Make sure that the device carries the following device label:

 II 3G (... followed by additional specifications).

 Observe the clause "Special Conditions for Safe Use ..." on the

following pages.

Special Conditions for Safe Use under Directive 94/9/EC, ATEX The Use in Hazardous Locations with explosive atmospheres is only allowed for MS4128-xxx or

HS600x model no´s. which are individually labelled Ambient temperature range “Ta: 0°C … + 60°C” ; Temperature Code “T4”.

The modules shall be installed in a suitable IP54 enclosure - with tool removable cover - in accordance with EN 60079-15, taking into account the environmental conditions under which the equipment will be used.

The power supply plugs P1 and P2 have to be secured by the supplied z-section sheet and M2.5 screw inclusive tooth washer. Provisions shall be made to prevent the rated voltage from being exceeded by

transient disturbances of more than 119 V. When the temperature under rated conditions exceeds 70 °C at the cable or conduit entry point, or 80 °C at the branching point of the conductors, the temperature specification of the selected

cable shall be in compliance with the actual measured temperature values. DO NOT OPEN WHEN ENERGIZED. Manufactured in 72654 Neckartenzlingen, Germany, by Hirschmann Automation and Control GmbH DOM: ww/yyyy (Date Of Manufacture: w - week, y - year – Refer to the device label.)
