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 Class I
of EN 61010 (115/230 AC power connections). 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.
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.
