General Guidance Notes

General Guidance Notes
SAFETY
The design of the CLARE G2000 Test Station meets the European Commission Directive No. 73/23/EEC, relating
to the “Low Voltage Directive”. This is in accordance with BS EN 61010-1: 1993 – Safety requirements for
electrical equipment for measurement control, and laboratory use. This unit is also compliant with the draft
European Standard prEN 50191:1997.
The design of the equipment is intended for use under the following conditions:
Indoors;
Altitude up to 2000 m;
Temperature 5°C to 40°C;
Maximum relative humidity 80% for temperatures up to 31°C to 50% at 40°C;
Mains supply voltage fluctuations of ±10% of the nominal voltage.
The user MUST follow the remainder of this section on safety, installation, guidance and maintenance to
guarantee safe operation and to maintain the equipment in a safe condition.
WARNING! This equipment requires a protective earth conductor. Do not use the equipment without a protective
earth conductor or intentionally interrupt the protective earth conductor.

General Guidance Notes
Do not remove or open the instrument cover - When connected to the mains supply, internal terminals of the
equipment will be live and the opening of covers or removal of parts is likely to expose live parts and create a risk
of electrical shock. The user must disconnect the equipment from ALL voltage sources before any adjustment,
replacement, maintenance or repair.
Fuse Ratings – For replacement purposes, the rated current and type of any internal, panel mounted or plugtop
fuses, where fitted, must be as specified. Typically these will be of the Mains Quick Blow Type F style. The user
must not use makeshift fuses or attempt to short-circuit fuse holders.
SAFE APPLICATION OF TEST EQUIPMENT
Any person operating electrical test equipment must be 18 years old or over and should have had adequate
training in the use of the particular piece of equipment. The degree of training should be appropriate for the
competence and experience of the operator and should be documented.
Site the test equipment in a clearly defined test area, with access limited to the operator only. Where possible
power outlet sockets should be of plastic construction and the test area should be free of steel conduit, trunking
and such like. Construct test benches of insulated material, preferably wood. The operator must stand on an
insulated, Earth free, surface such as British Standard approved rubber matting or nail-free duckboard. Provision
should also be made to allow the test item to be placed on an insulated surface.
DO NOT TOUCH OR CONTACT THE TEST ITEM WHILST OPERATING THE TEST EQUIPMENT.
KEEP THE TEST AREA CLEAN AND TIDY

General Guidance Notes
Please take adequate care with packing and arrange insurance cover against transit damage or loss when
returning the instrument – if possible use the original packing box and supports.
Regularly calibrate all test equipment to meet internal quality or regulatory licensing authority requirements and to
keep the equipment in a safe working condition. Return the equipment to Clare Instruments for this purpose.
Keep the equipment in a clean condition. Examine all input and test output leads and connectors regularly to
guarantee they are in a safe working condition.
The equipment contains parts that are specific to the equipment only, therefore, order spare parts from the above
address. Clare Instruments Ltd. strictly forbid any use of spare parts, other than those acquired from the original
manufacturer.
SUMMARY OF SAFETY INFORMATION
Should there be any doubt about location, setting up procedure or operation of the test equipment, contact Clare
Instruments Ltd. Report any apparent malfunctions immediately.
Maintain the test equipment in accordance with Health and Safety at Work Act and the Electricity at Work
Regulations. The supply socket used for connection to the incoming mains system should undergo earth loop
impedance measurements in keeping with the regulations to guarantee safe operation.
NOTE: Your Health and Safety Inspector may, with the benefit of on-site observations, offer alternate or additional
instructions to the above recommendations.

Introducing the CLARE G2000
Descriptions
1. Supply Switch - Rocker switch for switching the instrument on or off, illuminated in the ON position.
2. Earth Circuit meter – displays the ohmic value of the measured Earth path. A satisfactory reading will be
below 0.5 ohms (in the amber or uncoloured zones). Readings in the red zone, or beyond, may indicate a
poor or broken earth connection.
3. Set Zero control – used to set mechanical zero of the meter during factory build & calibration procedures. Not
normally required for user adjustment.
4. Set Inf. control – used for setting the full scale (INF) reading of the meter to compensate for mains
fluctuations, or differences, from location to location. Refer to Set-Up procedures for adjustment details.
5. Flash LN-E push button – used to apply 1500Va.c. Flash Test between Line + Neutral to Earthed parts for
Class I products or, in conjunction with the Flash Probe, for applying 4000Va.c. between L + N to outer
surfaces of Class II products.
6. Flash L-N push button – used to apply 1500Va.c. Flash Test between Line and Neutral circuits of both Class
I and Class II products.
Note
It is not advisable to apply a L-N Flash test to any product that requires a Light-Up test, particularly those that may
incorporate electronic control circuits or in-line transformers, the test may damage sensitive electronic
components. The Test Inhibit circuit should detect a L-N short and prevent the Light-Up test being applied.

7. Flash Fault lamp – lights to show that the product has failed the applied Flash test, an internal audible alarm
will also sound and the test voltage will be removed automatically. This lamp also acts as the Fault Reset
button, which must be momentarily depressed to cancel the fault indication and reset the safety trip circuit.
8. Safety push button – used in conjunction with the Light-Up test to minimize accidental operation.
9. Light-Up test keyswitch – applies mains voltage to the item under test, used as an alternative to the low
voltage continuity/polarity test for products that include ballasts, filter networks, in-line transformers and the
like, and therefore require full mains voltage to check correct operation.
THIS TEST SHOULD ONLY BE APPLIED FOLLOWING SATISFACTORY EARTH AND/OR FLASH TESTS.
10. Test Inhibit lamp – lights to indicate that internal protection circuitry has operated to prevent operation of the
Flash or Light-Up tests. Check that Continuity probes have been removed from lamp holders and/or that total
lamp load does not exceed 600 Watts.
