Safety instructions
Certified usage
Only use the device for application cases that are described in the
Hirschmann product information, including this manual. Only operate the
device according to the technical specifications.
Supply voltage
For
every
supply voltage to be connected, make sure the following
requirements are met:
Devices with DC power supply are designed for operation with a safety
extra-low voltage. Accordingly, only PELV or SELV circuits with
voltage restrictions in line with IEC/EN 60950-1 may be connected to
the DC supply voltage connections.
The supply voltage complies with the description on the data plate of
your device.
The complete defective plug-in power supply unit must be changed.
For safety reasons, the fuse installed in the plug-in power supply units
may not be changed.
Only switch on the device when the housing is closed. Close all empty
slots with a covering panel.
Screw the power supply units to the housing before connecting the
input voltage.
If you are using the M4-POWER power unit chassis: Check the
configuration of the connection plugs and the power supply cable to
the switch chassis before you connect an external voltage to the M4-
POWER inputs.
Only use connection cables that are permitted for a temperature range
from 0 °C to 60 °C.
Only use copper wire/conductors of class 1, 75 °C.
Only use the M4-POWER CABLE for the redundant power supply.
Only use the M4-POWER power supply unit for the redundant power
supply. Do not connect any other external voltage source.
Use undamaged parts.
Safe grounding
Make sure you ground the devices assembled in the switch cabinet
safely. In particular, check the supply voltage connections if they are not
connected directly to the supply cable (e.g. when using power strips).
Signal contacts (“FAULT”)
Only connect SELV circuits with voltage restrictions in line with IEC/EN
60950-1 to the signal contacts.
