1. Purpose
The lightning protection device TFortis SG-Switch is designed to provide
additional protection of 230 VAC supply circuits and Ethernet circuits of
TFortis PSW from severe interferences caused by powerful lightning
strikes. TFortis SG-Switch increases the level of lightning protection of
TFortis PSW switches up to class 5 (according to GOST R 51317.4.5)
Figure 1. Typical application scheme
Features
High level of protection against lightning interferences (class 5)
All-weather performance (IP66 housing)
Operation in a wide range of temperatures (from -55°C to 80°C).
Two types of protection in one device: 230 VAC and Ethernet
Quick replacement of the modules
Supports Fast/Gigabit Ethernet
Supports PoE/PoE+ (IEEE802.3af/at), including PoE 60W.
Convenient visual control of the modules integrity

2. Description
Figure 2. TFortis SG-Switch lightning protection device, appearance
TFortis PSW have standard built-in lightning protection of 230 VAC power
supply circuits and Ethernet (class 2 according to GOST R 51317.4.5,
performance criterion B). Since July 2017, all TFortis PSW switches are
manufactured with improved lightning protection (class 4 according to
GOST R 51317.4.5). TFortis SG-Switch increases the level of lightning
protection from class 4 to class 5 (GOST R 51317.4.5)
Note
"Performance criteria B" means temporary disruption of performance or
functioning with further recovery without operator's intervention

Note
Classification of technical equipment operating conditions according to
GOST R 51317.4.5:
Class 0
Protected electromagnetic environment, usually inside a specially equipped room.
Class 1
Partially protected electromagnetic environment.
Class 2
Electromagnetic environment in case of separation of power cables and signal
cables.
Class 3
Electromagnetic environment in case of parallel installation of power cables and
signal cables.
Class 4
Electromagnetic environment in case of installation of connecting cables outdoors
in the proximity of power cables and using multi-wire cables containing circuits of
electronic and electrically powered equipment.
Class 5
Electromagnetic environment in case of connecting technical equipment to
communication networks and overhead power lines in scarcely populated areas.
Class X
Special operating conditions established in the standards and technical
documentation for a particular type of technical equipment.

4. Operating conditions
TFortis SG-Switch lightning protection device is designed for 24/7 outdoor
operation at the ambient temperatures from minus 55C to plus 80C.
Meantime between failures at least 50 000 hours (5.7 years).
It is recommended to check the integrity of lightning protection device at
the beginning and the end of the storm season and immediately after the
storm.
5. Installation
5.1. Housing installation
The housing has four attachment points at the edges. Marking of the
attachment points is shown in Figure 3.
Figure 3. Attachment points marking
WARNING! Drilling of the housing will lead to loss of device integrity and,
as a result, loss of product warranty.
TFortis SG-Switch can be installed next to the TFortis PSW switch in the
same cabinet TFortis CrossBox-2 or CrossBox-3. These cabinets already
have a built-in optical distribution frame and DIN rail for circuit breakers.

5.2. Connecting power supply
Observe marking of the terminals when connecting the power cable to 230
VAC protection module.
Terminal IN –230 VAC input for connecting the power supply cable.
Terminal OUT –230 VAC output for connecting to TFortis PSW switch.
Figure 5. Functions of the connectors of 230 VAC lightning protection
module
Grounding of the switch is obligatory. Grounding resistant should not
exceed 4 Ohm.

5.3. Connecting the twisted pair
The protection module of Ethernet circuit is connected in parallel to the
protected lines. That is why there are no differences between input and
output connectors. The ports are equal. There are two connection modes:
A and B (Figure 6).
Fig. 6. Connection of the Ethernet cable.
When the lightning protection device SG-Switch is located in the same
cabinet wit TFortis PSW switch, it is allowed to use a non-shielded twisted
pair between these devices.
It is recommended to use a 4-pair twisted pair, at least category 5.
