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 9471 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.
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.
