3.0 SAFETY CONSIDERATIONS
3.1 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).
Unpacking & Inspection
Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate the unit if
damage is found.
This instrument is a panel mount device protected in accordance with EN 61010:2001, 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 mains supply cord.
Furthermore, to provide protection against excessive energy being drawn from the mains supply in case of a fault in the
equipment, an overcurrent protection device shall be installed.
• The Protective Conductor must be connected for safety reasons.
Check that the power cable has the proper Earth wire, and it is properly connected. It is not safe to operate
this unit without the Protective Conductor Terminal connected.
• 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.
