VARITECTOR SPC
Test possibility / V-TEST
Because the modules are pluggable,
it is possible to test the VSPC visually
or by using a V-TEST testing device.
The VSPC can be easily tested; the
user needs only to insert the VSPC
pluggable component into the V-TEST.
The result is then shown on the display.
The VSPC R modules also feature an
internal monitoring function for the
arrester. An error is the displayed at the
defective module. The VSPC CONTROL
UNIT can then transfer an alert to the
control room.
Reoccurring tests / V-TEST
Monitoring
The IEC 62305-3 requires testing and
maintenance for lightning protection
systems. This includes the testing of
the arresters used in the system.

Caution! These periodic inspections
may be extended with stricter

applications or regions.
Remote error diagnostics
VSPC R
When the VSPC module labelled “R” is
inserted into the corresponding “R”
base component, it is then possible
to use the outage alert function via
a two-pole plug. This screw/plug-in
connection has a clamping range from
0.5 to 1.5 mm².
The wire stripping length is
6 to 6.5 mm. A screwdriver with
a 2-mm blade width is used to
turn the screw. The VSPC Rs are
connected in succession to the
VSPC CONTROL UNIT evaluative
module. Up to ten VSPC Rs can
be connected in succession to the
VSPC CONTROL UNIT. The evaluative
module is supplied with 24 V DC. It
is then responsible for the switching
and for the voltage supply to the
VSPC modules. A no-voltage (oating)
CO contact can then be used to alert in
the event of an outage. The error on the
module, with the LED changing colour
from green to red. An automatic reset
is carried out by the VSPC CONTROL
UNIT within one minute after the
failed VSPC pluggable component is
replaced.

Installation
The VSPC series is appropriate for
protecting signal circuits. In order to
achieve a complete protective strategy
for the facility, the power feed must be
protected against Type II surge voltages
(for example, by using our VPU II
series). For existing lightning protection
facilities, Type I protection must be
used (for example, by using our VPU I
series). Type II protection (for example,
our VPU II) is sufcient when there is
no lightning protection in place.
Fusing
The VSPC surge protection modules are
designed so that they are decoupled
between the individual protective
stages.
The following must be observed when
providing fuse protection externally:
• Max. rated current
• Deratings curve
• Type of installation
• Application
