Safety Precautions
The test adapter has been 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 (draft)
Safety of the operator, as well as that of the
test adapter and the PRCD, is only assured
when it is used for its intended purpose.
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.
Read the operating instructions for the PROFITEST
MXTRA as well, in particular the sections con-
cerning the R
LO
, R
ISO
and time-to-trip measure-
ments, as well as the tripping test.
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.
Observe the following safety precautions:
•
The instrument may only be connected
to electrical systems with a maximum of
230/400 V which comply with applicable
safety regulations (e.g. IEC 60346, VDE
0100) and are protected with a fuse or
circuit breaker with a maximum rating of
16 A.
•
The test adapter may only be used for
testing PRCDs.
•
No power consuming devices may be
connected to the earthing contact and
CEE sockets.
•
The test adapter may not be used as an
extension cord.
•
Measurements within electrical systems
are prohibited.
•
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
(
PROFITEST MXTRA)
:
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.
•
Touch current at the probe socket is
limited by the internal protective circuit to
less than the maximum permissible value
of 0.5 mA in accordance with
DIN EN 61010-1.
•
Insulation resistance can only be mea-
sured at voltage-free objects.
•
Do not touch the insulation measuring
instrument’s test probes (
PROFITEST
MXTRA)
during insulation resistance mea-
surements!
•
Please observe the manufacturer‘s
details on the devices under test!
Fuse Replacement
All fuses for neutral and phase conductors
are accessible from the outside (see section
8.3). The fuses may only be replaced when
the instrument is voltage-free, i.e. the instru-
ment must be disconnected from mains
supply power and may not be connected to
a measuring circuit. The fuse type must
comply with the specifications in the techni-
cal data or the labeling on the instrument
(see section 7).
Opening the Instrument / Repairs
The test adapter may only be opened by
authorized, trained personnel in order to
ensure flawless operation and to assure that
the guarantee is not rendered null and void.
Even original replacement parts may only be
installed by authorized, trained personnel.
If it can be ascertained that the test adapter
has been opened by unauthorized person-
nel, no guarantee claims can be honored by
the manufacturer with regard to personal
safety, measuring accuracy, compliance
with applicable safety measures or any con-
sequential damages.
