
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 ... +60 °C (+32 °F ... +140 °F).

Only use copper wire/conductors of class 1, +75 °C (+167 °F).
 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”)
Exclusively connect SELV circuits with voltage restrictions according to
IEC 60950-1 or ES1 circuits according to IEC/EN 62368-1 to the signal
contacts.

Shielded ground
The shielded ground wire of the twisted pairs cables is connected to the
front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shield braiding.

ESD Guidelines
Media modules are equipped with electrostatically sensitive components.
These can be destroyed by the effect of an electric field or by charge
equalization when touching the printed circuit board or the contacts, or
their lifetime can be affected. Media modules are therefore delivered
packed in a conductive ESD protection bag. The packaging is reusable.
Make sure you adhere to the following protection measures for
electrostatically endangered assemblies:

Create electrical equipotential bonding between yourself and your
environment, e.g. using a wristband, which you clamp to the basic
device (knurled screw of an interface card). When the power supply
