Safety instructions

Certified use

Please observe the following points:

Z warning!

The equipment can only be used for the purpose and technical description described in the catalogue, and only with external equipment and parts recommended or approved by Hirschmann. The product can be handled correctly and safely only under the following conditions: it is transported, stored, installed and assembled correctly. In addition, care must be taken in operation and maintenance. The power supply voltage is supplied by NEC-class power supply through the mouse switch module.

For Ethernet power supply module: connect a NEC-only power supply. Use+60/75 c or+75 c copper wire only. Only zero potential supply voltage is used. Otherwise, ground the power supply through GND. The positive grounding of the power supply voltage is not allowed.

Shielding Ground Note: The shielding ground of the connectable twisted pairs lines is connected to the front panel as a conductor.

□ Beware of possible short circuits when connecting a cable section with conductive shielding braiding.

Casing z Warning! Only technicians authorized by Hirschmann are permitted to open the casing.

□ Make sure that the electrical installation meets local or nationally applicable safety regulations.

z Warning! Never insert pointed objects (thin screwdrivers, wires, etc.) into the inside of the subrack! This especially applies to the area behind the socket connectors. Failure to observe this point may result in injuries caused by electric shocks.

General Safety Instructions □ Particular attention is to be paid to all warnings and items of information relating to safety. □ Peripheral equipment must be suitable for the location in which it is used.

Warning! Any work that may have to be performed on the electrical installation should be performed by fully qualified technicians only
