3.2 Preparing the calibrator
Warning
•
The calibrator has been designed for indoor use only
and is not to be used in wet locations.
•
The calibrator is not to be used in hazardous areas,
where vapour or gas leaks, etc. may constitute a
danger of explosion.
•
The calibrator is not designed for operation in altitudes
above 2000 meters.
•
The calibrator is a CLASS I product and must be
connected to a mains outlet with a protective earth
connection. Ensure the ground connection of the
calibrator is properly connected to the protective earth
before switching on the calibrator. Always use a mains
power cable with a mains plug that connects to the
protective earth.
•
To ensure the connection to protective earth any
extension cord used must also have a protective earth
conductor.
•
Only use a mains power cord with a current rating as
specified by the calibrator and which is approved for the
voltage and plug configuration in your area.
•
Before switching on the calibrator make sure that it is
set to the voltage of the mains electricity supply.
•
Always position the calibrator to enable easy and quick
disconnection of the power source (mains inlet socket).
•
The calibrator must be kept clear within an area of 20
cm on all sides and 1 metre above the calibrator due to
fire hazard.
•
Never use heat transfer fluids such as silicone, oil,
paste, etc. in the calibrators. These fluids may
penetrate the calibrator and cause electrical hazard,
damage or create poisonous fumes.
