2 Safety
DANGER
Risk of electric shock
The contacts of the test adapter carry high
voltage during the test procedure!
►Do not use the device near explosive gases,
vapours or in a humid environment.
►Only press the “TEST” button if all 3 slots of
the test adapter are occupied (1 test object
and 2 empty enclosures).
► The clamping yokes carry high voltage. The
VPU IoT has to be cover under the instal-
lation hood before you press the bottom for
commissioning.
CAUTION
Risk from live parts
►Do not use damaged test leads.
►First connect the test leads to the test
adapter. Then connect the test leads to the
device.
►Never connect the test leads to live cables.
► Always make sure that all 3 slots of the test
adapter are occupied (1 test object and 2
empty enclosures).
►Do not insert any foreign objects into the
contact sockets of the test adapter.
►Do not use damaged product. First connec-
ted the wires of the energy grid, the cover
the VPU IoT with the hood. Do not insert
any foreign objects into the VPU BASE.
ATTENTION
►Only use the device for its intended purpose.
►The device must not be used if it is damaged or other
defects have been identied.
► The device must not be opened, modied or conver-
ted.
► Use only the specied spare parts and accessories.
►Use only the supplied test leads.
►Use the test leads only together with the supplied test
adapter.
►Replace the test adapter (order number 2661050000)
if the label is damaged.
►Only use the device for its intended purpose. The de-
vice must not be used if it is damaged or other defects
have been identied. The device must not be opened,
modied or converted.
The device must only be put into operation and
maintained by qualied electricians who are
familiar with national and international laws,
provisions and standards.
The device has double or reinforced insulation in
areas where dangerous voltages are present.
The device is supplied with a test adapter. The
test adapter is equipped with 3 empty enclo-
sures, which serve as placeholders (dummy ar-
resters).
The device must only be put into operations and
maintained by qualied electricians who are fa-
miliar with national and international laws, provi-
sions and standards.
2.1 Intended use
The VPU AC IoT is a surge protection device (SPD). It is
used for protecting low-voltage consumer installations and
electrical or electronic devices from the surge voltages
which occur from atmospheric discharges (lightning) or
from switching operations (transients).
The device detects overcurrent events as well as ground-
ing faults in the plant. The device can be connected to a
cloud via IoT.
The device must be mounted in a IP20 enclosure that is
accessible by authorised personnel only.

Transport and unpacking
2807610000/00/05.20216
►Transport the device to its destination in its original
packaging.
►Observe the instructions regarding handling, moisture,
shock, tilt and temperature indicators on the packaging.
► Observe the humidity specications and the temperature
range specied for transport.
►Protect the surfaces as necessary to prevent damage.
►When transporting the equipment or storing it temporar-
ily, make sure that the surfaces are protected from the
elements and any external inuences, and that they are
kept dry and clean.
3.1 Unpacking the VPU IoT
► Unpack the product and the instruction sheet.
The installation must be carried out by an
electrician.

The VPU AC IoT is a surge protection device (SPD) that
detects overcurrent events as well as grounding faults in
the plant. The device can be connected to a cloud enabling
digital services. The current device status (State of Health)
can be transferred and monitored via internet.
The measured data and detected events are transmitted
and permanently stored in the cloud. The current device
status is visualised and enables predictive maintenance
activities like replacement in time. The status can be SPD
fully functional, SPD still functional, replacement recom-
mended, SPD defective or replacement necessary.
The detection of transient overvoltages is very sensitive,
so that even the smallest events can be detected. Conclu-
sions about the power quality in a TNS or TT system can
be drawn from the number and frequency of events.
For the internet conenction a WiFi network is required with
reliable connection quality during the whole lifecycle of the
device. The Wi-Fi network must provide Internet access for
the device to deploy a public cloud endpoint.

The temporary hotspot mode is now activated for a period
of 10 minutes. After this time the hotspot mode is automati-
cally switched o󰀨.
►Connect the device with the tablet or laptop.
If the unit is in factory default mode or temporary hotspot
mode is enabled, the unit's SSID is displayed as VPU_AC_
IOT_xxxxx ( x = 6-LAST-CHARS-OF-MAC-ADDRESS).
