2-2 CWB / 1250_Op / Issue 9A
2.1 SAFETY
The 1250 has been designed in accordance with EN61010, "Safety requirements for
electrical equipment for measurement, control and laboratory use", and has been
supplied in a safe condition. This operating manual contains information and warnings
which must be followed by the user to ensure safe operation and to retain the equipment
in a safe condition.
The operating instructions include safety precautions where appropriate, but the
principal ones are also listed below.
2.2 GENERAL SAFETY PRECAUTIONS
1. Before switching on, ensure that the mains lead is connected to the ac supply in
accordance with the colour code.
2. Ensure that the mains voltage selector is correctly set.
3. Ensure that the mains plug is connected only to a mains outlet which has a protective
earth contact. This applies equally if an extension lead is used; the lead must
contain an earth conductor.
4. To effect earthing, the mains plug must be inserted before connections are made to
measuring and control circuits. The mains plug or external earth (as appropriate)
must remain connected until all measuring and control circuits have been
disconnected.
5. Any interruption of the earth connection (inside or outside the 1250) is prohibited.
6. When the 1250 is connected to its supply the opening of covers or removal of parts
could expose live conductors. The 1250 should be disconnected from all voltage
sources before it is opened for any adjustment, replacement, maintenance or repair.
Adjustments, maintenance or repair of the 1250 when it is powered should not be
attempted by the user. Consult a Solartron Service Centre if repairs are necessary.
7. Ensure that only fuses of the correct rating and of the specified type are fitted.
Makeshift fuses and short-circuiting of fuseholders is prohibited.
8. Whenever it is likely that the protection of the 1250 has been impaired, it should be
made inoperative and secured against any unintended operation. Protection could be
impaired if the 1250:
i) shows visible damage;
ii) has not been used as specified;
iii) has been operated outside the stated temperature range;
iv) fails to perform the intended measurements;
v) has been subjected to prolonged storage under unfavourable conditions;
vi) has been subjected to severe transport stress.
9. This symbol on the 1250 means 'Refer to the Operating Manual' for detailed
instructions or safety precautions.
In particular, care must be taken not to apply voltages in excess of the maximums
specified for each input and output. A summary of these is listed in the table below:
