Connections
Note:
Switch off the power supply before connecting or disconnecting the
instrument. Isolate the pneumatic pressures and depressurise the
pipes before connecting or disconnecting the instrument.
1.
Use an appropriate sealing method for all pressure connections.
2.
Before use, make sure the SELV power adaptor supplied with the
instrument is correct for the power supply voltage. The Safety Extra
Low Voltage (SELV) power adaptor complies with EN61010 (including
safety requirements for laboratory instruments).
Note: The instrument can be powered from other AC or DC power supplies
in the range 11 to 26 Volts. It is the user's responsibility to make sure
the power supply is safe.
3.
Connect the power adaptor to the instrument and switch the power
supply on.
