Safety
The product range of instruments is compliant with the requirements of BS EN
61010-1:1993 “Safety Requirements for Electrical Equipment for Measurement,
Control and Laboratory Use”. If the equipment is used in a manner NOT specified,
the protection provided by the equipment may be impaired.
Symbols
One or more of the following symbols may appear on the recorder labelling:
Static Electricity
All circuit boards and electronic modules associated with this recorder contain
components which are susceptible to damage caused by electrostatic discharge.
Should it be necessary to handle such components, appropriate precautions in
accordance with BS CECC 00015 “Basic specification: protection of electrostatic
sensitive devices” should be observed.
Installation Category
• Installation category - Installation category II, Pollution degree 2
For voltage, frequency and power see “Specifications” on page 6.
Fuses
There is one fuse situated on the power supply that can not be replaced by the
operator.
Symbol Meaning
Caution - refer to manual for instructions
Caution - risk of electric shock
Direct Current
Protective conductor terminal
Earth terminal

243-TV-25-20 GLO Issue 4 01/02 UK
A5E00117351-04
Cables
To fully comply with the requirements of the CE Mark, all cables connected to the rear
of the unit should use screened cable terminated at both ends. Also a low impedance
earth cable (<1 mΩ) should be connected to the earthing stud on the rear of the recorder.
WARNINGS AND SAFETY PRECAUTIONS
Do’s and Don’ts
1. Before any other connections are made to the recorder, the protective earth terminal
should be connected to a protective conductor.
2.
In order to comply with the requirements of safety standard EN61010, the recorder
should have one of the following as a disconnecting device, located within easy reach of
the operator, and be clearly labelled as the disconnecting safety device:
• A switch or circuit breaker which complies with the requirements of IEC947-1 and
IEC947-3.
• A separable coupler which can be disconnected without the use of a tool.
• A separable plug, without a locking device, to mate with a socket outlet in
the building.
3. Whenever it is likely that protection has been impaired, the recorder should be made
inoperative and secured against operation. The manufacturer's service centre should be
contacted.
4. Any adjustment, maintenance, and repair of the opened recorder in a powered condition
is hazardous and should never be attempted.
5. Where conductive pollution such as condensation or conductive dust is present, ade-
quate air conditioning, filtering and/or sealing must be installed.
6. This recorder contains a battery which must be treated and disposed of with care. Bat-
teries must not be short circuited. Batteries should be disposed of in accordance with
local regulations, they must not be disposed of with normal refuse. See “Appendix B -
Battery Safety Data Sheet” on page 85.
IMPROPER INTERRUPTION OF CONNECTIONS
Any interruption of the protective conductor outside the recorder, or disconnection of
the protective earth terminal is likely to make the recorder dangerous under some
fault conditions. Intentional interruption of the protective conductor is dangerous.
Failure to comply with these instructions will result in death or serious injury.
