Safety instructions
This manual contains instructions which must be observed to ensure your
own personal safety and to avoid damage to devices and machinery.
U
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 Hirschmann. 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.
U
Supply voltage
For reasons of safety, the fuse installed in the slide-in power supply units
must not be changed.
V
The complete defective plug-in part must be replaced.
V
Only switch on the device when the housing is closed. Close all empty
slots with a panel.
V
The devices may only be connected to the supply voltage shown on
the type plate.
V
The DC modules (M4-...-...VDC 300W) are designed for operation with
a safety extra-low voltage. Thus, they may only be connected to the
supply voltage connections with PELV circuits or alternatively SELV
circuits with the voltage restrictions in accordance with IEC/EN 60950.
V
For the case where the DC modules (M4-...-...VDC 300W) are opera-
ted with external power supply: Use only a safety extra-low voltage in
accordance with IEC 950/EN 60 950/VDE 0805 to power the system.
V
Connect the power supply cord only if the power supply unit is tightly
screwed to the chassis.
V
If you are using the M4-POWER power unit chassis: Check the
configuration of the connection plug and the power supply cable
to the switch chassis before you connect an external voltage to the
M4-POWER inputs.
V
Only use connecting cables which are permitted for a temperature
range from 0°C to 60 °C.
Relevant for North America:
V
Use 60/75°C or 75°C copper(CU)wire only.
U
Shielding ground
The shielding ground of the connectable twisted pairs lines is connected
to the front panel as a conductor.
