2. Safety and EMC Information
This indicator is intended for industrial temperature and
process applications when it will meet the
requirements of the European Directives on Safety and
EMC. Use in other applications, or failure to observe
the installation instructions of this handbook, may
impair safety or EMC. The installer must ensure the
safety and EMC of any particular installation.
Safety
This indicator complies with the European Low Voltage
Directive 2006/95/EC, by the application of the safety
standard EN 61010.
Electromagnetic compatibility
This indicator conforms with the essential protection
requirements of the EMC Directive 2004/108/EC by the
application of a Technical Construction File. This
instrument satisfies the general requirements of the
industrial environment defined in EN 61326. For more
information on product compliance, refer to the
Technical Construction File.
GENERAL
The information contained in this manual is subject to
change without notice. While every effort has been
made to ensure the accuracy of the information, your
supplier shall not be held liable for errors contained
herein.
Unpacking and storage
The packaging should contain an instrument mounted
in its sleeve, two mounting brackets for panel
installation and an Installation & Operating guide.
Certain ranges are supplied with an input adapter.
If on receipt, the packaging or the instrument is
damaged, do not install the product but contact your
supplier. If the instrument is to be stored before use,
protect from humidity and dust in an ambient
temperature range of -10
O
C to +70
O
C.
Service and repair
This indicator has no user serviceable parts. Contact
your supplier for repair.
Caution: Charged capacitors
Before removing an instrument from its sleeve,
disconnect the supply and wait at least two minutes to
allow capacitors to discharge. It may be convenient to
partially withdraw the instrument from the sleeve, then
pause before completing the removal. In any case,
avoid touching the exposed electronics of an
instrument when withdrawing it from the sleeve.
Failure to observe these precautions may cause
damage to components of the instrument or some
discomfort to the user.
Electrostatic discharge precautions
When the indicator is removed from its sleeve, some of
the exposed electronic components are vulnerable to
damage by electrostatic discharge from someone
handling the indicator. To avoid this, before handling
the unplugged indicator, discharge yourself to a
ground.
Cleaning
Do not use water or water based products to clean
labels, or they will become illegible. Isopropyl alcohol
may be used to clean labels. A mild soap solution may
be used to clean other exterior surfaces of the product.
2.1 Installation Safety Requirements

Helpful hints
Personnel
Installation must only be carried out by suitably
qualified personnel in accordance with the instructions
in this handbook.
Enclosure of Live Parts
To prevent hands or metal tools from touching parts
that may be electrically live, the indicator must be
enclosed in an enclosure.
Caution: Live sensors
The indicator is designed to operate if the temperature
sensor is connected directly to an electrical heating
element. However, you must ensure that service
personnel do not touch connections to these inputs
while they are live. With a live sensor, all cables,
connectors and switches for connecting the sensor
must be mains rated for use in 230Vac +15% CATII.
Wiring
It is important to connect the indicator in accordance
with the wiring data given in this guide. Take particular
care not to connect AC supplies to the low voltage
sensor input or other low level inputs and outputs.
Only use copper conductors for connections (except
thermocouple inputs) and ensure that the wiring of
installations comply with all local wiring regulations.
For example, in the USA, use NEC Class 1 wiring
methods. In the UK, use the latest version of the IEE
wiring regulations (BS7671).
Power Isolation
The installation must include a power isolating switch
or circuit breaker. This device should be in close
proximity to the indicator, within easy reach of the
operator and marked as the disconnecting device for
the instrument.
Overcurrent protection
The power supply to the system should be fused
appropriately to protect the cabling to the units.
