Safety Warnings

2 Safety Features and Precautions

This instrument fulfills the requirements of applicable European

and national EC directives. This is confirmed by means of the CE

mark. A corresponding declaration of conformity can be

requested from GMC-I Messtechnik GmbH.

The test system test system 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

IEC 61577 / EN 61577 / VDE 0413-2, -4

When used for its intended purpose, the safety of the user, the

test system and the device under test (electrical equipment or elec-

trical medical device) is assured.

Read the operating instructions carefully and completely before placing

your test system 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 by a qualified electrician, or under

the supervision and direction of a qualified electrician. The user

must be instructed by a qualified electrician in the execution and

evaluation of tests.

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 supply

systems with 230 V/240 V which conform to the valid safety

regulations (e.g. IEC 60364, 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 de-

vices under test (for example, capacitors may be dangerously

charged).

• Make certain that the measurement cables are in flawless condi-

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

• Insulation resistance measurement (equivalent leakage current)

Testing is conducted with up to 500 V. Current limiting is uti-

lized (I < 10 mA), but if the terminals (L and N) are touched,

electrical shock may occur which could result in consequential

accidents.

• Measuring leakage current

It is absolutely essential to assure that the device under test is

operated with line voltage during performance of leakage cur-

rent measurements. Exposed conductive parts may conduct

dangerous contact voltage during testing, and may not under

any circumstances be touched (mains power is disconnected if

leakage current exceeds approx. 10 mA).

• Function test

Attention!

The function test may only be performed after the DUT

has successfully passed the safety test!.For reasons of

safety, the device under test must be switched off before

the function test is started. This precaution prevents in-

advertent start-up of a device under test which may rep-

resent a hazard during operation, e.g. a circular saw or a

disc grinder.

Ending the Function Test: After completion of the function

test, devices under test must be turned off with their own

switch – especially devices with relatively high inductivity.
