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.
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.
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.
Disconnection Device
When powered from a mains supply this unit requires the provision of a suitable mains isolation
device to be accessible near to the installed instrument.
