Legal notice
This manual contains important notes and warnings that could lead to serious personal and property
damage if ignored. Please read this manual carefully prior to commissioning the e-light 2MA switches.
Correct transport, correct storage, and installation and careful operation and maintenance of the e-
light 2MA are critical for safe operation.
Intended use
The devices in the e-light 2MA product family may only be operated as described in this manual. These
may only be used free of damage and according to the indicated environmental conditions. The
enclosure of the e-light 2MA may only be opened by eks technicians; the devices do not contain any
components that must be maintained by the customer.
Personnel requirements
Installation and commissioning of the e-light 2MA may only be completed by trained personnel who are
familiar with this operating manual. Furthermore, all work on electrical systems may only be completed
by an electrician or under their direction and supervision. Applicable local and national safety conditions
must be maintained at all times.
Voltage supply
The devices in the e-light 2MA product family have been designed for operation with SELV voltages via an
LPS (Limited Power Source). These may only be powered via SELV/LPS conform with IEC 60950-
1/EN60950-1/VDE0805-1, which in turn are supplied with voltage via NEC Class 2 conform voltage
supplies.
The shielding of the RJ45 sockets is connected with the enclosure of the e-light 2MA to discharge faults.
Note any possible short circuits when using shielded cables.

2Hardware Description
The front of the e-light 2MA switches is equipped with extensive displays, which provide information
concerning the current status of the devices. In addition to USB data line connections and the RS232 line
for configuration, there is also a reset button for resetting the device to the factory settings in case of an
unknown IP address and a labeling field for entering the programmed IP address.

2.2 Reset button
The reset button can be used to restart the switch or to reset the configuration to the initial value:
Restart: Hold the button pressed down for a second and release it as soon as all LEDs light up.
The switch is now restarted.
Reset to initial value: Hold down the button for 5 seconds. The switch resets the complete
configuration to the standard settings and signals this after shutting off all LEDs briefly.
2.3 DIP switches
The e-light 2MA switch features nine dip switches for configuring settings. The dip switches will be
connected in one of the next firmware versions. Currently, their status is not queried.
2.4 LED displays
The front panel of the switch features 5 diagnosis LEDs. Furthermore, each of the Ethernet ports
features two status LEDs. Optical ports feature optical ports FiberView.
The LED displays offer real-time information regarding the status of the e-light 2MA, see Table1.

2.5 Ports
2.5.1 RJ-45 ports
The e-light 2MA features four, six or eight RJ-45 ports, depending on the design, each with transfer
rates of 10 mbps or 100 mbps. The ports detect the data rate automatically. Sending and receiving
lines are crossed appropriately via MDI/MDI-X auto-crossover so that connections are able to be
established with other devices, independent of the cable type used (1:1 or crossed).
2.5.2 Optical ports
The e-light 2MA is equipped with up to four 100Base-FX ports, depending on the design. Depending
on the variation ordered, the LWL ports may have different plug connectors (ST, SC,) and be
suitable for different fiber types (multi-mode, single-mode).
Please make sure that the transceivers of the e-light 2MA are always connected with transceivers of
other devices that are suitable for the same wavelength and the same fiber type.
With the exception of Bidi transceivers, which cannot send and receive simultaneously via one
fiber, the transmitters of a device must always be connected with the receiver of the opposite
device and vice-versa.

2.5.3 Wiring
Use twisted-pair cable of category 5 or better to connect the RJ-45 ports. The electrical
connection cable between the switch and the connection partner (switch, hub, workstation,
etc.) may not be longer than 100 meters. Use metal shielded connectors on the cables.
Connect the multi-mode transceiver with 50/125 µm or 62.5/125 µm multi-mode optical fiber
cables.
Connect the single-mode transceiver with 9/125 µm single-mode optical fiber cables.
2.5.4 Voltage supply connection
Connect the supply voltage to VDC1 and GND clamping terminals. The redundant supply voltage
may now be connected to the VDC2 and GND clamping terminals. The terminal block for the voltage
supply is clamping and can be locked using two screws. Both voltage inputs feature reverse voltage
protection.
The permissible range for the input voltage is between 12 VDC and 60 VDC. The voltage must be
SELV/LPS-conform voltage as per IEC 60950-1/EN60950-1/VDE0805-1. Please observe the
instructions for SELV voltages according to the legal instructions at the beginning of this operating
manual.

Note: Please tighten the screws and check that all connections are stable.

Note: Please note the corresponding cable cross-section of at least 0.5 mm2or 12~ 24 AWG during
wiring.
2.5.5 Differential relay connection
Clamping terminals K1/K2 and K3/K4 each feature a potential-free differential relay contact. The
relays act as alarm receivers and can be connected in the software with different alarm triggers.
Depending on the configuration, they activate, for example, in case of a voltage failure, RJ45 port
error or a LWL port error. In the software, the relay between K1 and K2 is marked relay 1, and the
relay between K3 and K4 is marked relay 2.
Figure 3: Relay terminal clamp
Note: The capacity of the relay contact amounts to 25 VDC (1A) of 60 VDC (0.3A).

2.6 Installation on DIN mounting rail
The e-light 2MA switches are equipped with a fastener for 35 mm top-hat rails as per DIN EN 60175.
To install the top-hat rails, snap the devices onto the top side of the rail (Figure 4 left) and then
press downward against the spring force in the top-hat rail clip (1) and then into the assembly plate
(2). The top-hat rail fastener locks via spring force (3) as depicted in the Figure 4 right.
Figure 4: Installation on DIN mounting rail
For disassembly, follow the steps indicated above in the reverse sequence.
Optional to the top-hat rail fastener, a wall installation mount can be delivered. If the system is
fastened with the wall installation mount, then the top-hat rail fastener must be removed first.

Warning!
Do not mount e-light 2MA switches directly beside devices that produce strong electromagnetic
interference fields, e.g. transformers, contactors, frequency inverters, etc.
Warning!
Do not mount e-light 2MA switches directly next to heat producing devices and protect the switch
against direct sunlight in order to prevent unwanted heating.
Warning!
When operating in ambient temperatures above 50°C, the enclosure of the e-light 2MA switches
may heat above 70°C. Do not install the devices in areas that are accessible by unqualified
personnel.
Warning!
When operating in ambient temperatures above 50°C, measurements must be taken to check how
severely the plug connectors of the cables used heat up. Use of special cables that are suitable for
ambient temperatures above 80°C may be required.
Note:
In case of use on ships, e-light 2MA switches may not be fastened with the top-hat rail fastener on a
35 mm rail. The top-hat rail does not provide secure mounting. On ships, e-light 2MA switches must
be fastened using the wall installation mounting.
