Measuring Adapter BENNING MA 2-16
1
1. Application
With the
BENNING MA 2-16
measuring adapter you can test
devices equipped with a 5-pin 16 A/ 6h CEE plug quickly and
efficiently. To do this connect the adapter to a tester for
testing
portable
devices
in
compliance
with
DIN VDE 0701-0702 or for testing in compliance with
DIN EN 62353 (VDE 0751-1) or DIN EN 60974-4 (VDE 0544-4),
that has only a shock-proof socket for connecting to the test
sample and that can measure protective conductor current
directly.
The adapter is suitable for connection to the appliance testers
BENNING ST 755
and
BENNING ST 760
.
The following tests can be carried out with the measuring
adapter on appliances with CEE plugs:
Test of the continuity of the protective conductor system
Test of insulation
Measurement of the protective conductor current with
the method:
direct measurement method/ differential and alternative
leakage current
Functional test
Attention!
Restriction of the application
The
BENNING MA 2-16
measuring adapter may only
be used for testing purposes in combination with tester
types
BENNING ST 755
and
BENNING ST 760
. Any
other use of the adapter, in particular for permanent
connection of three-phase appliances to a three-
phase mains, is not permissible under any
circumstances!
The maximum permissible thermal continuous
current in all cases is 16 A AC per phase.
2. Safety features and measures
The measuring adapter is constructed and tested in
compliance
with
the
safety
regulations
IEC 61010-1/ EN 61010-1/ VDE 0411-1. The safety of users
and the device is guaranteed if it is used for its intended
purpose.
The device may only be connected to a TN, TT or IT power
supply of max. 240 V/ 400 V, which complies with the
applicable safety regulations (e. g. IEC 60346, VDE 0100) and is
secured with a maximum nominal current of 16 A.
Before use please read this instruction manual carefully and
completely and in particular the instruction manual of the
tester with which you intend to use this measuring adapter.
Observe and follow all points included in the instructions.
The adapter may only be used for testing appliances with a
5-pin CEE plug and a maximum current consumption of
3 x 16 A (AC-1).
The measuring adapter must not be used:
with the housing open
if there are any signs of external damage
if the CEE socket or connection cable are damaged
after severe overuse, i. e. exceedance of the load limits
in the technical specifications
after storage over a longer period of time under
unfavourable conditions
(e. g. humidity, dust, temperature)
Meanings of the symbols on the device
Attention: Observe documentation!
This symbol means that the instructions in the
instruction manual must be observed in order to
prevent danger.
CAT II
Device in the measuring category II
Earth (voltage to earth)
This symbol on the measuring adapter means
that the measuring adapter conforms to the EU
directives.
The device must not be disposed of with
household waste. You will find more information
about the WEEE symbol on the Internet under
the search term WEEE.
3. Connecting the BENNING MA 2-16
Before you can start testing, you have to connect the
BENNING MA 2-16
to your tester and the mains. To do this
proceed as follows:
Connect the mains cable of your tester to the shock-
proof socket on the
BENNING MA 2-16
marked “mains
connection
tester“.
Connect the protective contact line of the
BENNING MA 2-16
to the test/ mains socket of your
tester. The connection on the
BENNING MA 2-16
is
marked
“for test/ mains socket tester”.
Connect the CEE connection lead of the
BENNING
MA 2-16
to a suitable CEE socket 16 A/ 6h in your
electrical
installation.
The
connection
on
the
BENNING MA 2-16
is
marked
“3~/ N/ PE, 400 V, 50-60 Hz, 16 A”. From this time onwards
the
BENNING MA 2-16
and your tester will be supplied
with electrical power.
Finally connect your test sample to the CEE socket of
the
BENNING MA 2-16
. The socket is marked
“Test/ mains socket test sample 16 A”.
You can now start the tests. (s. Chapter.4)
4. Testing with the BENNING MA 2-16
All tests that you can carry out with your tester on devices
with a shock-proof plug and that are supported by the
BENNING MA 2-16
adapter
can now be carried out in an
identical manner on devices with a CEE plug. Proceed here
as indicated in the operating manual of your tester.
The following special features of the
BENNING MA 2-16 adapter must be taken into
account during testing with the tester.
In the case of an insulation or alternative leakage
current test, the three phase connections L1, L2, L3 and
N of the test sample are short-circuited in the adapter
and then the tests carried out.
In the case of a protective conductor resistance test, the
value of the measured protective conductor resistance
is increased by the proportion that is caused by the
protective conductor system of the
BENNING MA 2-16
measuring adapter itself.
