2 SAFETY
The 1253 is designed in accordance with the EN61010, ‘Safety Requirements for
Electrical Equipment for Measurement, Control and Laboratory Use’, and is supplied in
a safe condition. This operating manual contains information and warnings that must be
followed by the user to ensure safe operation and to keep the equipment in a safe
condition.
The operating instructions include safety precautions where appropriate, but the
principal ones are also listed below.
2.1 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 that has a protective
earth (ground) 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 he 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 1253) is prohibited.
6. When the 1253 is connected to the ac supply, the opening of covers or removal of
parts could expose live conductors. The 1253 should be disconnected from all
voltage sources before it is opened for any adjustment, replacement, maintenance
or repair. The user should not attempt adjustments, maintenance or repair of the
1253 when it is powered. If repairs are necessary, consult a Solartron Service
Centre.

2. Lever the hinged flap open with a screwdriver and lift out the voltage selector
roller block.
3. Refit the block with the chosen voltage value facing outwards.
4. Check that the fuses fitted are of the correct value (Section 4.2 below) and, if
necessary, change them.
5. Close the flap securely, checking that the correct value shows through the aperture.
6. Plug in the mains connector again.
4.2 MAINS FUSES
Live and Neutral are both fused in the 1253. Fig. 2.1 shows how these fuses are
accessed, after the mains connector has been unplugged. The arrowheads marked on
each fuseholder must align with those on the flap when the fuseholders are refitted.
The fuse values are:
T1.6A, for 220V or 240V setting
T3.15A, for 100V or 120V setting
Replacement fuses must be 20mm × 5mm cartridge type.
4.3 MAINS LEAD
An ac mains connector lead, complete with a mating socket for the IEC plug on the 1253
mains input unit, is supplied appropriate to the destination country.
This lead should be connected to the user's ac supply according to the following colour
code:
BROWN =LIVE
BLUE =NEUTRAL
GREEN/YELLOW =EARTH
An IEC socket and lead other than the one supplied may be used, but it must be correctly
wired as shown in Fig 2.2.

4.4 CONNECTION PROCEDURE
1. Before connecting the supply, ensure that the mains voltage selector on the rear
panel is correctly set (Section 4.1), and that the fuses fitted in the mains input unit
are correctly rated (Section 4.2).
2. Ensure that the power on/off switch is ‘off’. This switch is located next to the
mains input unit on the rear panel.
3. Connect the mains lead.
4. Switch the 1253 ‘on’ at the rear panel.
5 REPLACING GENERATOR FUSES
Two 400mA fuses protect the 1253 Generator, one in series with the Hi output and one
in series with the Lo. If the Generator appears to be inoperative, before inspecting or
replacing these fuses, check the following points:
a. Is the Generator ‘on’? If not, press SINGLE or RECYCLE.
b. Are all connections with the system under test OK?
c. Is the Generator menu set correctly, with the Amplitude parameter non-zero?
Refer to Chapters 3 and 5 for procedure.
d. Is the START/STOP input on the rear panel being held low?
e. Disconnect the 1253 from the system under test. Set up a measurement and
confirm the Generator is inoperative by monitoring the output with an oscilloscope
or suitable voltmeter.
If none of these indicate a problem external to the Generator then one or more of the
Generator fuses may have failed. This may be because the Generator output has been
subjected to a large external voltage in the system under test. Refer to Chapter 12:
Specifications, for Generator capabilities.
To replace or inspect the fuses follow the procedure described in Section 4.1.
