4.3 Connecting the system to an electricity source
Each system module requires a separate, grounded power source. The ground connection in all
power outlets must be common and located in close proximity to the system.
Recommendation: Use a line conditioner and uninterrupted power supply (UPS) for optimum,
long-term, input voltage stability.
To connect the system to an electricity source:
1. Connect the female end of the power cord to the receptacle on the rear panel of each
module.
2. Connect the male end of the power cord to a grounded wall outlet.
Alternative: If your system includes the optional FlexCart, connect the female end of the
FlexCart's electrical cables (included in the startup kit) to the receptacle on the rear panel of
each system module. Connect the hooded, male end of the FlexCart's electrical cables to
the power strips on the back of the cart. Finally, connect each power strip's cable to a wall
outlet operating on its own circuit.
Note: The optional FlexCart is available for core 1 system configurations, only.
Warning: To avoid electrical shock, observe these precautions:
• Use only the power-supply cable provided when the system module was installed.
• Use SVT-type power cord in the United States and HAR-type power cord, or better, in
Europe. For requirements elsewhere, contact your local Waters distributer.
• Inspect the power cord for damage, and replace it, if necessary.
• Power-off and unplug each module before performing any maintenance operation on the
module.
• Connect each module to a common ground.
