2 Safety Features and Precautions

This instrument fulfills the requirements of the applicable European and

national EC guidelines. We confirm this with the CE marking. The relevant

declaration of conformity can be obtained from GMC-I Messtechnik

GmbH.

The test instrument has been manufactured and tested in accordance

with the following safety regulations:

IEC 61010-1 / DIN EN 61010-1 / VDE 0411-1, DIN VDE 0404, DIN VDE

0413 Part 2 and 4 and DIN VDE 0104 (Feature F02 or

SECULIFE ST

)

Only when used for its intended purpose, the safety of the user, the test

instrument and the device under test (electrical equipment or electrical

medical devices) is assured.

Read the operating instructions carefully and completely before placing your test

instrument into service, and 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 super-

vision of a qualified electrician. The user must be instructed by a qualified

electrician concerning performance and evaluation of the test.

Note

Manufacturers and importers of electrical medical devices must

provide documentation for the performance of maintenance by

trained personnel.

Observe the following safety precautions:

• The instrument may only be connected to electrical systems with

230 V/240 V

which conform to the 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.

• Measurements within electrical systems are prohibited.

• Be prepared for the occurrence of unexpected voltages at devices

under test (for example, capacitors can be dangerously charged).

• Make certain that the measurement cables are in flawless condition,

e.g. no damage to insulation, no interruptions in cables or plugs etc.

• When using a probe with coil cable (SK2W):

Grip the test probe firmly, for example after 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

This test is performed with a maximum voltage of 500 V, with a current

limit having been set (I < 3.5 mA). However, contacting the terminals

(3 or 2) causes an electric shock which, in turn, may result in accidents.

• Leakage Current Measurement

During leakage current measurement it is imperative to ensure that the

device under test is operated at line voltage. Exposed conductive parts

may be charged with hazardous contact voltage during the test and

may consequently not be touched under any circumstances. (There is

a power shutdown as soon as the leakage current is higher than ap-

prox. 10 mA).

Attention!

The function test may only be performed after the DUT has

successfully passed the safety test!

Switching loads on and off

When switching the DUT on or off under load it is imperative that you ad-

here to the order indicated below. This helps to prevent excessive wear

and tear of the mains relays at the test instrument.

Before the measurement:

1) DUT: Switch the DUT off at the proprietary switch.

2) SECULIFE ST or SECULIFE ST

HV:

Apply line voltage to the test socket .

3) DUT: Switch on the DUT at the proprietary switch.

After the measurement:

4) DUT: Switch the DUT off at the proprietary switch.

5) SECULIFE ST or SECULIFE ST

HV:

Disconnect the test socket from the line .

The measuring and test instrument may not be used:

• If it demonstrates visible damage

• With damaged connector cables, measuring cables or patient ports

• If it no longer functions properly

• After extraordinary stresses due to transport

In such cases, the instrument must be removed from operation and

secured against unintentional use.
