Preparing for Operation
Prepare the detector for use according to the specifications in this chapter.
2.1 Rear panel connections
When making connections to the QDa detector’s rear panel, refer to the figure in Appendix D , on
page 80 .
For details of supported inlet system configurations, contact Waters Technical Service.
2.2 Connecting to the electricity source
The ACQUITY QDa requires a separate, grounded (earthed) electricity source. The ground
connection in the electrical outlet must be common and connected near the system.
To connect to the electricity source:
Recommendation: Use a line conditioner and uninterruptible power supply (UPS) for optimum
long-term input voltage.
1. Connect the female end of the power cord to the receptacle on the rear panel of the
detector.
2. Connect the male end of the power cord to a suitable wall outlet.
Alternative: If your system includes the optional FlexCart, connect the female end of the
cart’s electrical cable (included in the startup kit) to the receptacle on the rear panel of the
instrument. Connect the hooded, male end of the cart’s electrical cable to the power strip on
the back of the cart. Finally, connect the power strip’s cable to a wall outlet operating on its
own circuit.
Warning: To avoid electrical shock, observe these precautions:
• Use the SVT-type power cord in the United States and the HAR-type (or better) in
Europe. The main power cord must be replaced with one of adequate rating. To learn
which cord to use in other countries, contact your local Waters
®
distributor.
• Power-off and unplug the detector before performing any maintenance on the
instrument.
• Connect all components of the ACQUITY inlet system to a common ground.
