B.10 Connecting to the power supply
The instrument requires a separate, grounded power source. The ground connection in the
electrical outlet must be common and connected near the system.
To connect to the power source:
Recommendation:
Use a line conditioner or an uninterruptible power supply (UPS) for
optimum long-term input voltage stability.
Warning:
To avoid electric shock, use the SVT-type power cord in the United States
and HAR-type (or better) in Europe. The main power cord must be replaced with one of
adequate rating. For information regarding what cord to use in other countries, contact
your local Waters distributor.
1. Connect the female end of the power cord to the receptacle on the rear panel of the
instrument.
2. Connect the male end of the instrument power cord to the 200 to 240 V AC wall outlet.
3. Connect the power cord from the roughing pump relay box to the 200 to 240 V AC wall
outlet.
Tip:
The system software controls electrical power to the pump.
