1 Application
The permanently mounted SECUTEST 21F test panel is intended
for use by electricians as workshop equipment. It’s used to mea-
sure and test electrical devices after repair or modification, as well
as for periodic testing in accordance with DIN VDE 0701-0702.
According to these regulations, protective conductor resistance,
insulation resistance and equivalent leakage current must be
measured, and testing must be conducted for the absence of
voltage at user accessible conductive parts at data processing
equipment and office machines.
The measurement of operating voltage and current consumption
at devices under test, as well as testing for conductor continuity,
represent further applications for the substantiation of correct
functioning of electrical equipment. Beyond this, the protective
conductor at the mains connection can be tested for the absence
of voltage and line voltage can be measured.
2 Safety Precautions
The test panel is equipped with a test
instrument, and has been manufactured and tested in
accordance with the following regulations:
IEC/EN 61010-1/
VDE 0411-1 Safety requirements for electrical
equipment for measurement, control and
laboratory use; general requirements
DIN VDE 0404 Testing and measuring equipment for
testing the electrical safety of electrical
devices, part 1; General requirements, and
part 2: Devices for periodic testing
When used for its intended purpose, the safety of the user, the
test instrument and the device under test (electrical equipment) is
assured.
Read the operating instructions carefully and completely before placing
your test instrument into service. Follow all instructions contained
therein. Make sure that the operating instructions are available to all
users of the instrument.
Tests may only be performed under the supervision of a qualified
electrician. The user must be instructed by a qualified electrician
concerning performance and evaluation of the test.
Observe the following safety precautions:
The test panel may only be connected to a 220/380 V or
230/400 V mains system with 50 Hz and three 32 A fuses.
Measurements within electrical systems are prohibited.
The outlet at the bottom left-hand corner of the test panel with
the designation “Netzsteckdose 16 A/230 V” (mains outlet)
(23) is always live with line voltage, regardless of any selected
switch positions, as soon as the test panel is connected to the
mains.
The “Netzsteckdose” corresponds to the “Functional mains
outlet” at the METRATESTER.
All other outlets on the test panel (17 through 21) are live with
line voltage when the VDE / NETZ switch (13) is in the “NETZ
position. These outlets (17 through 21) correspond to the test
socket at the METRATESTER.
Be prepared for the occurrence of unexpected voltages at
devices under test. For example, capacitors may be
dangerously charged.
Before connecting the device under test to the test panel,
subject it to a thorough visual inspection first. Devices under
test with visibly damaged insulation must be repaired before
metrological testing is performed.
If the test panel demonstrates visible damage, no longer
functions, has been stored for a lengthy period of time under
unfavorable conditions or has been subject to excessive
stress during transport, it must be assumed that hazard-free
operation is no longer possible. If this is the case, remove the
test panel from service and secure it against inadvertent use.
