Connecting the Power Supply
1 Make sure the voltage setting shown on the rating plate matches the line
voltage.
The operating voltage cannot be switched over.
2 Make sure the power supply leads have an adequately dimensioned
protective device (breaker).
3 Install a switched outlet or a breaker in the power supply wiring near the
sample gas feed unit. This should allow the sample gas feed unit to be
completely disconnected from the power supply if necessary.
The disconnection device should be easily accessible and identified in such a
way that its relationship to the equipment that it is designed to disconnect
can be clearly seen.
4 Connect the delivered power supply cable to the power supply.
The sample gas feed unit may start when the power supply is connected.
