4. At the bottom of the surge arrester, attach the
top-hat rail support with washer and screw. The
bracket of the top-hat rail support must point to
the side of the surge arrester with the inscription
EQUIP.
5. Install one surge arrester for each communication output and (where necessary)
communication input as follows:
• Mount the surge arrester on the top-hat rail. Observe the indicated mounting position (see
Section 4.2, page 24). The terminal EQUIP must point to the left.
• Fasten the end clamp immediately above or below the surge arrester on the top-hat rail.
☑ The end clamp audibly clicks into place and the surge arrester can no longer be
moved on the top-hat rail.
6. Connect the electronic assembly to the surge arrester for the communication output:
• Plug the RJ45 connector on the supplied Ethernet cable into the EQUIP terminal of the
surge arrester.
• Connect the other end of the Ethernet cable on the electronic assembly to the terminal X7
according to the circuit diagram. Observe the prescribed cable route.
• Attach the Ethernet cable in the SMA String-Monitor with the cable brackets.
• Push the mounting tie onto the bracket of
the DC load-break switch and secure the
Ethernet cable in position with the cable tie.
7. For the communication output, connect the surge arrester to the enclosure opening for
communication:
• Route the Ethernet cable for the communication output through the enclosure opening for
communication (see Section 4.1, page 22)into the SMA String-Monitor. To do this, pierce
the membrane and push the Ethernet cable through the membrane.
• Connect the RJ45 connector to the inserted end of the Ethernet cable in accordance with
EIA/TIA 568B (8-conductor) (see manual of RJ45 connector). Make sure that no pieces
of cable are dropped into the SMA String-Monitor.
• Route the Ethernet cable to the surge arrester in the cable channel according to the cable
route. To do this, remove the cover of the cable channel, lay the Ethernet cable inside and
replace the cover.
