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 DIN rail mount device. 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 947Ð1 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.

If a rail assembly is to be transported, then
disconnection, dismounting and separate
packing of the power supply is
recommended.

For units that must be shipped installed on
the rail, additional bracing to resist
transportation shocks is recommended.

Do not attempt to install or connect to the
power supply when the mains are
energized.

Warning!

Warning: Do not turn on the ac power to the power supply

unit until you have completed all output connections. Failure
to do so may result in injury!

This device must only be installed electrically by a specially
trained electrician with corresponding qualifications.

Warning: To avoid potential electric shock use National
Electrical Code (NEC) safety practices when wiring and
connecting this unit to a power source.
