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.
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 prepared as described in the instrument Site Preparation
Guide .
3. Connect the power cord from the roughing pump relay box to the 200 to
240 V AC wall outlet prepared as described in the instrument Site
Preparation Guide .
Tip:
The system software controls electrical power to the pump.
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.
