Safety notices on the use of the device

The following safety notices must be adhered to when setting up and operating the device
and during all work relating to it such as installation, connecting up, replacing devices or
opening the device.

General notes

WARNING

Safety extra low voltage

The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS). (This does not apply to 100 V...240 V devices.)

This means that only SELV / LPS complying with IEC 60950-1 / EN 60950-1 / VDE 0805-1
must be connected to the power supply terminals. The power supply unit for the equipment
power supply must comply with NEC Class 2, as described by the National Electrical Code
(r) (ANSI / NFPA 70).

There is an additional requirement if devices are operated with a redundant power supply:

If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.

WARNING

Opening the device

DO NOT OPEN WHEN ENERGIZED.

Information on use in hazardous areas according to ATEX

WARNING

Requirements for the cabinet/enclosure

To comply with EU Directive 94/9 (ATEX95), this enclosure must meet the requirements of
at least IP54 in compliance with EN 60529.

If the cable or conduit entry point exceeds 70 °C or the branching point of conductors
exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C, only use cables with admitted maximum operating temperature
of at least 80 °C.

WARNING

Protection against transient voltage surges

Provisions shall be made to prevent the rated voltage from being exceeded by transient
voltage surges of more than 40%. This criterion is fulfilled, if supplies are derived from
SELV (Safety Extra-Low Voltage) only.

Information on use in hazardous areas according to UL-HazLoc

WARNING

EXPLOSION HAZARD

DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE
NON-HAZARDOUS.

This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or non­hazardous locations only.

3.2 EM496-4 extender for media modules

Four additional slots for media modules

Note

The EM496-4 extender module can be used only in conjunction with the SCALANCE X414­3E.
The SCALANCE X408-2 has no port for an extender module.

By adding the media module extender, the basic device is extended by four slots that you
can equip with the following modules as required:

● MM491-2

● MM491-2LD

● MM491-2LH+

If you use all slots, you have an additional eight optical Fast Ethernet ports available (100
Mbps).

Note

For data transfer with this extender module, the minimum requirement is an occupied slot
(for example, no. 1). The installation of the extender module and the removal and insertion of
a media module from/in the required slot (for example no. 1) is NOT possible during ongoing
operation.

Note

The required slot (for example no. 1) must remain occupied to allow the removal and
insertion of the other media modules (for example slots 2-4) during ongoing operation.

The media module plug connectors are protected by protective caps.
