General notices
This manual is intended for the installer of the SIP Ring Switch described in the ma-
nual and must be read and understood before starting work. The devices are to be
installed and put in operation only by qualied personnel.
Intended use
1DANGER
The SIP Ring Switch manufactured by Wiesemann & Theis are network remote swit-
ches with integrated web server and digital in- and outputs. They are used as a re-
mote switching and monitoring unit, accessible via TCP/IP-Ethernet using various
web and network protocols in accordance with the present manual.
Non-intended use is any other use or any modication to the described devices.
Electrical safety
1WARNING
Before beginning any kind of work on the SIP Ring Switch you must completely dis-
connect it from power. Be sure that the device cannot be inadvertently turned on
again!
The SIP Ring Switch may be used only in enclosed and dry rooms.
The device should not be subjected to high ambient temperatures or direct sunlight,
and it should be kept away from heat sources. Please observe the limits with res-
pect to maximum ambient temperature.
Ventilation openings must be clear of any obstacles. A distance of 10-15 cm be-
tween the SIP Ring Switch and nearby heat sources must be maintained.
Input voltage and output currents must not exceed the rated values in the specica-
tion.

Safety notices
When installing be sure that no stray wires stick out through the ventilation slit of
the SIP Ring Switch into the housing. Ensure that no individual wires stand off from
leads, that the lead is fully contained in the clamp and that the screws are tightly
fastened. Fully tighten screws on unused terminals.
The power supply used for the SIP Ring Switch must absolutely ensure safe
isolation of the low-voltage side from the supply mains according to EN60950-1 and
must have “LPS“ designation.
EMC
1NOTE
Only shielded network cables may be used for connecting the SIP Ring Switch to the
network.
In this case the SIP Ring Switch meet the noise immunity limits for industrial
applications and the stricter emissions limits for households and small businesses.
Therefore there are no EMC-related limitations with respect to the usability of the
devices in such environments.
The complete Declarations of Conformity for the devices described in the manual can
be found on the corresponding Internet page at the W&T homepage: http://www.wut.
de.
Batteries
The SIP Ring Switch contains a 3V lithium-manganese dioxide button battery type
CR1632 for backing up the internal clock. This battery has an expected lifetime of
10 years and must be replaced only by a battery of the same type.
When using the SIP Ring Switch in a network environment with access to a time
server, the battery is not essential for correct function of the device and can be
removed.
1CAUTION
The battery may be removed or replaced by an electrotechnical specialist, only.
To remove the battery, open the housing as follows:

Rasthaken
Batterie
Use a pointed object to press on the latching hooks on the side of the housing and
at the same time pull the bottom of the housing out of the top shell.
Then remove the stack of PCBs downwards from the housing.
The buffer battery for the clock module is located in a holder on the upper PCB.
After removing/replacing the battery, reassemble in reverse order.
Batteries and rechargeables must not be disposed of with normal waste, recycling
of used batteries and rechargeables is required by law. Used batteries may contain
harmful substances which can damage the environment or your health if not
disposed of properly.
Batteries also contain important raw materials such iron, zinc, manganese or nickel
and are recycled.

IP address assignment
Install Wutility-Tool (Download: http://wut.de/wutility)
After starting Wutility your SIP Ring Switch appears in the device list. If multiple
devices are shown, please identify your device by the Mac address, that is printed
on a white sticker at the device: “EN = 00c0:3d......“ . If there is a DHCP server in your
network, you can use the assigned IP address for a rst test. Using the IP address
icon in WuTility you can assign a free static IP address instead to the SIP Ring
Switch.
Function test
Open the Web page of the SIP Ring Switch in a web browser using the address
http://<IP-address of the SIP Ring Switch>.
