S AF E T Y
The design of the B433R 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 EN 50191.
The design of the equipment is safe when used under the following conditions:
Indoor use;
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 is a safe condition.
WARNING! Any interruption of the protective earth conductor (mains input earth) inside or outside the equipment
is likely to make the equipment dangerous. The user must not intentionally interrupt the protective earth
conductor.
When connected to the mains supply, internal terminals of the equipment may be live and the opening of covers
or removal of parts is likely to expose live parts. The user must disconnect the equipment from ALL voltage
sources before any adjustment, replacement, maintenance or repair.
Use only fuses with the required rated current and of the specified type for replacement. Mains Quick Blow Type
F for plug top and ‘Safebloc’ output connectors. The user must not use makeshift fuses or short-circuit fuse
holders.
The user should carry out manual handling of test equipment in accordance with regulatory guidance notes. That
is those supplied by the Health & Safety Executive or Croner’s and the Health & Safety at Work Act.

Electrical safety tests (particularly Flash Tests) are required to comply with Legislative Documents on electrical
and electronic product testing which may encroach the EMC (Electromagnetic Compatibility) requirements. This
standard came into effect on 1 st January 1996.
The design of the test equipment will minimise the effects of electromagnetic disturbances, but some interference
may result from particular applications dependent on the type of product being tested.
Therefore, the user is responsible for installing and using the test equipment according to the manufacturers’
instructions. The user of the test equipment is responsible for detecting electromagnetic disturbances and must
resolve the situation with the technical assistance of the manufacturer. In some cases it may involve constructing
an electromagnetic screen (Faraday cage) enclosing the test equipment and test pieces complete with associated
input filters. The user should achieve a reduction in electromagnetic disturbances to a point where they are no
longer troublesome.
