SECTION 1.2 SAFETY CONSIDERATIONS
This device is marked with the
international caution symbol
. It is
important to
read
this manual before installing or commissioning this device as it contains
important information relating to
Safety and EMC
(Electromagnetic Compatibility).
This instrument is a
panel mount
device protected in accordance with
EN 61010-1:2001, electrical safety requirements for electrical equipment for
measurement, control and laboratory. Installation of this instrument should be
done by qualified personnel. In order to ensure safe operation, the following
instructions should be followed.
This instrument has
no power-on switch
. An external
switch or circuit-breaker
shall be included in the building installation as a disconnecting device. It shall be
marked to indicate this function, and it shall be in close proximity to the equipment
within easy reach of the operator. The switch or circuit-breaker shall not interrupt
the Protective Conductor (Earth wire), and it shall meet the relevant requirements
of IEC 947–1 and IEC 947-3 (International Electrotechnical Commission). The
switch shall not be incorporated in the main supply cord.
Furthermore, to provide protection against
excessive energy
being drawn from
the main supply in case of a fault in the equipment, an
overcurrent
protection
device shall be installed.
•
Do not exceed voltage rating on the label located on the top of the instrument
housing.
•
Always disconnect power before changing signal and power connections.
•
Do not use this instrument on a work bench without its case for safety
reasons.
•
Do not operate this instrument in flammable or explosive atmospheres.
•
Do not expose this instrument to rain or moisture.
•
Unit mounting should allow for adequate ventilation to ensure instrument does
not exceed operating temperature rating.
•
Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to
minimize electrical shock hazards.
EMC Considerations
•
Whenever EMC is an issue, always use shielded cables.
•
Never run signal and power wires in the same conduit.
•
Use signal wire connections with twisted-pair cables.
•
Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.
Failure to follow all instructions and warnings may result in injury
