SAFETY CONSIDERATIONS
Unpacking & Inspection
Unpack the instrument and inspect for obvious shipping damage. Do not attempt to
operate the unit if damage is found.
For instruments with AC Voltage and AC Current inputs, observe the input signal
connections in the appropriate section of this manual. These instruments must only
be installed by professional electricians.
• Do not exceed voltage rating on the label located on 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!
