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
Class II of EN 61010 (115/230 ac power connections), Class III for the
low voltage power option (12 - 36 Vdc or 24 Vac). Installation of this
instrument should be done by a 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!
