SAFETY NOTES
WARNING
Any interruption of the protective conductor inside or outside the apparatus, or disconnection of
the protective earth terminal is likely to make the apparatus dangerous under some fault condi-
tions. Intentional interruption is prohibited.
Note: in order to comply with the requirements of safety standard BS EN61010, the recorder shall
have one of the following as a disconnecting device, fi tted within easy reach of the operator, and
labelled as the disconnecting device.
a. A switch or circuit breaker which complies with the requirements of IEC947-1 and IEC947-3
b. A separable coupler which can be disconnected without the use of a tool
c. A separable plug, without a locking device, to mate with a socket outlet in the building.
1. Before any other connection is made, the protective earth terminal shall be connected to a protec-
tive conductor. The mains (supply voltage) wiring must be terminated within the connector in such
a way that, should it slip in the cable clamp, the Earth wire would be the last wire to become discon-
nected.
2. In the case of portable equipment, the protective earth terminal must remain connected (even if the
recorder is isolated from the mains supply), if any of the I/O circuits are connected to hazardous volt-
ages*.
3. The mains supply fuse within the power supply is not replaceable. If it is suspected that the fuse is
faulty, the manufacturer’s local service centre should be contacted for advice.
4. Whenever it is likely that protection has been impaired, the unit shall be made inoperative, and se-
cured against accidental operation. The manufacturer’s nearest service centre should be contacted
for advice.
5. Any adjustment, maintenance and repair of the opened apparatus under voltage, should be avoided
as far as possible and, if inevitable, shall be carried out only by a skilled person who is aware of the
hazard involved.
6. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/fi l-
tering/sealing etc. must be installed in the recorder enclosure.
7. Signal and supply voltage wiring should be kept separate from one another. Where this is impracti-
cal, shielded cables should be used for the signal wiring.
8. If the equipment is used in a manner not specifi ed by the manufacturer, the protection provided by
the equipment might be impaired.
* A full defi nition of ‘Hazardous’ voltages appears under ‘Hazardous live’ in BS EN61010. Briefl y, under
normal operating conditions, hazardous voltages are defi ned as being > 30V RMS (42.2V peak) or > 60V
dc.
