Safety Notice
The information in this safety notice is for the prevention of injury to personnel and
damage to the instrument.
The manufacturer assumes no liability for injury or damage caused by misuse of the
instrument or for modifications made to the instrument.
This document must be consulted in all cases where the following “Caution” safety symbol is
used :
Qualified Personnel
The instrument must be installed, operated and serviced by persons who have been properly
trained and authorised. Personnel must read and understand this manual prior to installation and
operation of the instrument. Refer to section 3 for further information regarding permitted
maintenance operations. The safety of any system incorporating the equipment is the
responsibility of the assembler of the system.
Static Hazard
The 500 series flow computer uses high speed CMOS circuitry which is sensitive to static
damage. The user should observe accepted safety practices for handling electronic devices,
especially during servicing. Once the unit is installed, grounded and interconnected, the chances
of static damage are greatly reduced.
Voltage Hazard
Before connecting power to the instrument, ensure that the supply voltage for the AC or DC
input is suitable. The AC voltage rating is as stated on the instrument rating plate. Personnel
should take all due care to avoid electric shock. For safe operation it is essential to connect a
mains safety earth to the A.C. power inlet. Do not operate at altitudes above 2000m.
Welding Hazard
Do not perform electric welding in close proximity to the instrument or its interconnecting
cables. If welding in these areas must be performed, disconnect all cables from the instrument.
Failure to do so may result in damage to the unit.
Moisture Hazard
To avoid electrical faults and corrosion of the instrument, do not allow moisture to remain in
contact with the instrument. Operate only in a clean, dry and pollutant-free environment.
Operating & Storage Temperature
Operating: If a heater is being used, DO NOT isolate the instrument in temperatures below
-20°C.
Storage: DO NOT store the equipment below -20°C.

Disconnection Device
When powered from a mains supply this unit requires the provision of a suitable mains isolation
device, capable of interrupting both poles of the supply and meeting your local wiring
regulations, to be suitably located and easily accessible near to the installed instrument. It must
be marked as the disconnecting device for the equipment. It must be suitably rated with respect
to the cross sectional area of the supply conductors.
Instrument Disposal
Contrec instrumentation should not be thrown into the general waste system.
If within EU member states, this instrument should be disposed of according to
the guidelines set by the WEEE (Waste Electrical and Electronic Equipment)
directive 2012/19/EU. If outside of the EU, this equipment should be
responsibly disposed of according to local and national regulations for EEE
(Electrical and Electronic Equipment).
By not discarding of this product along with other house hold waste you are
preserving natural resources and reducing waste sent to landfill and incinerators.
Remove batteries and dispose of separately (see Disposal of Batteries) before disposal of
Contrec instrumentation.
Disposal of Batteries
Batteries have an environmental impact. Safe and responsible disposal should
be undertaken.
In all EU member states, as per Directive 2006/66/EC, batteries must not be
thrown away with general waste. Contact your local environmental authority
for information regarding disposal or recycling of used batteries, alternatively
they can be returned directly to Contrec Ltd. for disposal.
Please Contact Contrec Ltd before returning batteries for disposal.
Explanation of IEC Symbols Used
You should familiarise yourself with the following symbols which are used both within this
manual and on the instrument itself.
This document must be consulted in all cases where the following “Caution” safety
symbol is used.
