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).

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.
• 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.
