Surge protection for photovoltaic systems
Lightning and surge protection
for photovoltaic systems
Class I and II lightning and overvoltage protection
Weidmüller‘s surge protection type PU I protects low-voltage consumer
installations and electronic devices against direct lightning effects and
overvoltages that can occur through atmospheric discharges (thunderstorms)
or by switching operations (transients).
The PU I- and II-series meet the requirements of Class I and II
in accordance with IEC 61643-1:2008 and the type 1 and type 2
comply with EN 61643-1.
Function indication, maintenance and homologations
The PU II surge protection modules are provided with an optical control.
The indicator is controlled by a thermal disconnection unit. If this unit has
“answered”, there is no protection, so the colour of the indicator changes
from green to red. A qualified person can replace the inoperative arrester
without disconnecting the wiring. The pluggable varistor modules are coded
in compliance with their voltage. Thus it is only possible to plug a suitable
replacement varistor.
Pluggable and codable protection elements
Easy and safe exchange due to coded modules
and bases.
High leakage current
High energy absorption with lmax: 40 kA (8/20 μm) and Uoc:
6 kV with short response time.
High pulse currents with IImp up to a maximum of
30 kA (10/350 µs).

Surge protection for photovoltaic systems
Surge protection on the energy supply side
Lines can be charged with high currents and voltages following
a lighting strike. This can lead to permanent damage and loss
of the photovoltaic system. The use of lightning arresters and
surge protection devices results in a higher system availability
and better profit. Weidmüller offers a complete range for
protection in accordance with IEC 60364-7-712 for the energy
input for both roof-mounted systems and large-scale systems.

Surge protection for photovoltaic systems
Surge protection on the PV generator side
For the DC voltage side, Weidmüller also offers a complete
range for protection with surge voltage arresters. These are
suitable for both roof-mounted and large-scale systems alike.
For cable lengths of more than 10 m between the PV generator
and the inverter, protection is needed at both ends. This means
that both the generators and the inverter are protected.
External lightning protection available
No external lightning protection

SPD II 3 PV (according to UL 1449 Ed. 3)
Page 62
Failure to comply with the separation distance S
If the separation distance S according to EN 62305 is not observed (S < min), then partial lightning currents need to be taken into
account. There should be a shielded generator main line with sufficient cross-sectional area (min. 16 mm²) used. The adjacent picture
shows an implementation that reaches LPZ 1. Here the surge protection from class II arrester can be installed in line with the
standards (product selection, see above).
Ready-made standard solutions
Weidmuller offers an extensive range of combiner boxes with overvoltage protection
for the DC side. It comprises solutions pre-wired for 1 to 16 string applications in
various versions.
The complete overview of our standard solutions can be found on pages 44 to 51.

Surge protection for photovoltaic systems
Surge protection for data and communication devices
Pluggable surge protection for instrumentation, control and automation
circuits
The pluggable VARITECTOR SPC surge protection stands out due to highest
protection characteristics in combination with compact design. The protection element
of the module can be removed, measured or replaced during operation without
affecting the impedance and without breaking the instrumentation circuit of the wiring.
These characteristics make the product an ideal protection element for interfaces in
I&C systems.
With the VARITECTOR SPC R modules, error detection and failure indication are
effected via internal monitoring. A green LED indicates active protection. A red
LED stands for failure. This information is forwarded to the V-Control evaluation
module. From here it can be signalled, for instance, to a control unit. The
V-TEST testing device, monitoring the function of VARITECTOR SPC,
also facilitates the observance of service intervals. The testing method is
in accordance with the IEC 62305 standard.
A VARITECTOR SPC module can be used instead of a modular terminal
when removing the protection module without affecting the impedance.
Four binary or 2 analogue signals only require 17.8 mm of space on the
mounting rail. Easy latching onto the earthed rail also saves time during
installation. Colour codes mark the different voltage levels of all
VARITECTOR SPC modules thus facilitating service during operation.
The EMC-SET that is available as accessory, offers additional comfort
for the connection of shielded cables. All VARITECTOR products are
in compliance with the “overstress mode” required by the valid
IEC 61643-21:2008 standard.
Space saving
Saving space in the control cabinet:
4 binary signals or 2 analogue signals
at 17.8 mm
In compliance with the norms
For applications according to the IEC 62305: high impulse currents
of up to 20 kA (8/20 µm) are safely discharged to PE. Tested according
to the IEC 61643-21:2008 standard for classes D1, C2 and C1.

Surge protection for photovoltaic systems
VARITECTOR SPC
Pluggable surge protection for the instrumentation,
control and automation technology
Weidmüller‘s VARITECTOR SPC pluggable surge protection is
remarkable for its combination of extremely high protective
functionality and compact dimensions. It is suited for use in
measurement and control circuits.
The size is made possible by the seletion of installation
dimensions, with a width of 17.8 mm (1TE).
Two versions are available:
• VSPC: a surge protector
with no monitoring function
• VSPC R: a surge protector
with monitoring function
The base components are plugged in to form a direct earthing
contact via the mounting rail. Thus you save time during the
connection. The VARITECTOR SPC series is optimally designed
for compact installation locations in process automation,
industrial automation or building automation. The two-stage
surge-protection base components are equipped with gas
discharge tubes, suppressor diodes (TVS) and decoupling
components. Individual protective components (such as gasfilled spark gaps, varistors and suppressor diodes) supplement
this product line. IEC 62305 requires that a periodic inspection
of surge protection products be conducted. The functionality of
all VARITECTOR SPC modules can be tested using testing

equipment (such as the V-TEST) that is available separately. The
VARITECTOR SPC R modules also feature an internal
monitoring function. The green LED signals when the protection
function is ready. The red LED signals an error. Up to ten
modules can be wired together in series. The modules signaling
an evaluative module (the VSPC CONTROL UNIT) in the event
of an error. VARITECTOR SPC-series surge protection is
available with rated voltages of 5 V, 12 V, 24 V, 48 V and 60 V.
The product‘s voltage level is colour-coded on the pluggable
arrester. An earthing contact is established by snapping onto an
earthed TS35 rail.
The TS35 must be earthed in order to ensure safe power
discharging via the terminals of up to 20 kA (8/20 µs) and 2.5
kA (10/350 µs). The rail must be screwed onto the earthed
mounting plate for reasons of EMC. In order to optimize the
protective function, a PE-contact connection should be made
over the VSPC module every 60 cm for equipotential bonding.
The pluggable protective element can be pulled out during
operations without interrupting the measurement circuit.

Testing device for surge protection
V-TEST testing device
A testing device for pluggable surge protection:
for testing in compliance with the IEC 62305-3 standard
The V-TEST is a compact and portable testing device intended for the
pluggable VARITECTOR SPC (measurement and control) and the PU I/PU II
(power supply) surge protection product lines. This testing device can be
used to check the functionality of Weidmüller’s surge protection components
in accordance with the test intervals stipulated in IEC 62305-3. It indicates
the functional state of protective components.
The display shows the measured reading per component
(GDT, MOV, TAZ) as „ok“ or „not ok“. This function allows you
to detect ageing components by displaying possible damages
right away. Thus total protection in guaranteed.
The V-TEST is equipped with a charger and a battery
set which allows autonomous use in the field. A comfortable
and protective carry bag is delivered free with the tester.
Always delivering precise readings
The V-TEST self-calibrates when it is turned on,
ensuring that it can always deliver precise
measurement and test values.
Portable
The compact device comes with an integrated
rechargeable battery and protective case –
making it perfect for use in the field.
Quick and easy to operate
It only takes a few simple menu steps
(in German or English) to navigate
directly to the measurement function.
