SECUTEST ST BASE(10) / PRO und SECULIFE ST BASE(25)
1 Safety Precautions
SECUTEST ST BASE(10), SECUTEST ST PRO and
SECULIFE ST BASE(25) test instruments are
manufactured and tested in accordance with
the following safety regulations:
IEC/EN 61010-1 / VDE 0411-1, DIN VDE
0404, IEC/EN 61577 / VDE 0413-2,-4 /
DIN
EN 61557-16 / VDE 0413-16
The “automatic test sequences” are semi-
automatically controlled sequences whose
progress is interrupted by safety-relevant
stoppages and the associated warnings and
instructions. As a result, the level of protec-
tion provided to the user is greater than
demanded by sections 4.1.6 and 4.1.7 of
DIN EN 61557-16 with regard to “automatic
test sequences”.
The safety of the user, the test instrument
and the device under test (electrical equip-
ment or electrical medical device) is only
assured when the instrument is used for its
intended purpose.
Read these condensed operating instructions and the
full operating instructions carefully and completely
before placing your test instrument into service (avail-
able at our homepage www.gossenmetrawatt.com for
download). Follow all instructions contained therein.
Make sure that the operating instructions are available
to all users of the instrument.
Tests may only be performed by a qualified
electrician, or under the supervision and
direction of a qualified electrician. The user
must be instructed by a qualified electrician
concerning performance and evaluation of
the test.
Suitable personal safety equipment is
required.
If you use any active or passive implanted
medical devices, please consult your doctor
or the manufacturer of these devices.
Manufacturers and importers of electrical
medical devices must provide documen-
tation for the performance of mainte-
nance by trained personnel.
Observe the following safety precautions:
• The instrument may only be connected to
electrical systems (TN, TT or IT) with a maxi-
mum of 240 V which complies with applica-
ble safety regulations (e.g. IEC 60346, VDE
0100) and is protected with a fuse or circuit
breaker with a maximum rating of 16 A.
• Measurements within electrical systems
are prohibited.
• Be prepared for the occurrence of unex-
pected voltages at devices under test
(for example, capacitors can be danger-
ously charged).
• Make certain that the measurement
cables are in flawless condition, e.g. no
damage to insulation, no cracks in
cables or plugs etc.
• When using a test probe with coil cord
(SK2W): Grip the tip of the test probe
firmly, for example during insertion into a
jack socket. Tensioning at the coil cord
may otherwise cause the test probe to
snap back resulting in possible injury.
•
Measurement of insulation resistance and
equivalent leakage current
(leakage current
alternative measuring methods)
Testing is conducted with up to 500 V. Cur-
rent limiting is utilized (I < 3.5 mA), but if
terminals L or N at the test socket are
touched, electrical shock may occur which
could result in consequential accidents.
•During operation with line voltage:
Exposed conductive parts may conduct
dangerous touch voltage during testing.
Do not touch under any circumstances!
Use a special cover in order to avoid
touch contact.
Mains power is disconnected at the
instrument if leakage current exceeds
approx. 10 mA (can be switched to 30
mA). However, this does not fulfill the
requirements specified for a PRCD. If the
“Proceed in case of limit violation” setting
is used, enhanced safeguarding against
touch contact and a 30 mA RCD must
be used, and personal protective equip-
ment (PPE) must be worn (secure work-
station).
