SAFETY NOTES（ 工业记录笔、工业记录纸 ）
1. Before any other connection is made, the protective earth terminal shall be connected to a protective con-ductor. The Mains (supply voltage) wiring must be terminated in such a way that, should it slip in the cable
clamp, the Earth wire would be the last wire to become disconnected.
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 voltages*. 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 conditions. Inten-tional 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, fitted 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
3. The mains supply fuse within the power supply unit is not replaceable. If it is suspected that the fuse is faulty, the
manufacturer's local service centre should be contacted for advice.
4. Batteries within recorders are not user replaceable. Contact the manufacturer's local service centre if a problem is
suspected. 工业记录笔、工业记录纸
5. Whenever it is likely that protection has been impaired, the unit shall be made inoperative and secured against
unintended operation. The nearest manufacturer's service centre should be consulted for advice.
6. Any adjustment, maintenance and repair of the opened apparatus under voltage, should be avoided as far as possi-ble and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.
7. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/sealing
etc. must be installed in the recorder enclosure.
8. Signal and supply voltage wiring should be kept separate from one another. Where this is impractical, shielded
cables should be used for the signal wiring.
9. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
might be impaired

A full definition of "Hazardous' voltages appears under 'Hazardous Live' in BS EN61010. Briefly, under normal
operating conditions, hazardous voltages are defined as > 30V RMS (42.2V peak) or > 60V dc.
