Hazardous Voltage
Hazardous Voltages are defined by EN61010-1 as follows:
4
Warnings and Safety Precautions
3. Repair is not to be attempted by a customer. Any adjustment or maintenance expected
of an operator as part of the normal operation of the product is referred to as Opera-
tional Maintenance. Any maintenance not expected of the operator is referred to as
Corrective Maintenance and is to be carried out only by authorized service personnel
or returned to an authorized repair centre.
4. Where conductive pollution such as condensation or conductive dust is present, ade-
quate air conditioning, filtering and/or sealing must be installed.
5. This recorder contains one battery on the Processor board which must be treated and
disposed of with care. Batteries must not be short circuited. Batteries should be dis-
posed of in accordance with local regulations, they must not be disposed of with normal
refuse.
Improper signal and supply wiring - WARNING
6.
WARNING
IMPROPER SIGNAL AND SUPPLY WIRING
Signal and supply wiring should be kept separate. Where this is impractical, shielded cables should
be used for the signal wiring. Where signal wiring is carrying, or could carry under fault conditions,
hazardous voltage (defined as >30 V rms and 42.4 V peak, or >60 Vd.c.), double insulation must
be used for all signal wiring.
Failure to comply with these instructions could result in death or serious injury.
7. If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be inadequate.
8. The protective earth terminal must remain connected (even if the recorder is isolated
from the mains supply) if any of the measuring, communications, or relay terminals are
connected to hazardous voltages.
WARNING
HAZARDOUS VOLTAGE LEVELS
Voltage levels above 30V rms and 42.4V peak or 60V dc are deemed to be
"Hazardous Live". Ensure operators are not exposed to hazardous voltage levels.
Failure to comply with these instructions could result in death or serious injury.
