Waters ACQUITY - 2 Preparing for Operation; Rear Panel Connections; Connecting to the Electricity Source

2 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.
When making connections between the QDa detector’s rear panel and the ACQUITY Diverter
Valve's rear panel, refer to the figure in Diverter valve wiring.
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 electricity source. The ground connection in
the electrical outlet must be common and connected near the system.
Warning: To avoid electric shock, observe these precautions:
• Use SVT-type power cords in the United States and HAR-type power cords, or
better, in Europe. For requirements elsewhere, contact your local Waters distributor.
• Inspect the power cords for damage, and replace them, if necessary.
• Power-off and unplug each module before performing any maintenance operation
on it.
• Connect each module to a common ground.
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 start-up 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
