Connecting to the electricity source
The CM-30S requires a separate, grounded power source. The ground
connection in the power outlet must be common and physically close to the
CM-30S.
To connect to the electricity source:
Recommendation:
Use a line conditioner and 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 CM-30S (see page 22 ).
2. Connect the male end of the power cord to a suitable wall outlet.
Monitoring LEDs
Light emitting diodes on the CM-30S indicate its functional state.
Power LED
The power LED, to the left-hand side of the CM-30S’s front panel, indicates
when the CM-30S is powered-on or powered-off.
Run LED
The run LED, to the right of the power LED, indicates the status of the
CM-30S. It glows steady green when the CM-30S is running a method. The
run LED is unlit when the module is idle and functioning normally.
Warning:
To avoid electrical shock, observe these precautions:
• Use power cord SVT-type in the United States and HAR-type or
better in Europe. For other countries’ requirements, contact your
local Waters distributor.
• Inspect the power cord for damage and replace it, if necessary.
• Power-off and unplug the CM-30S before performing any
maintenance operation on it.
• Connect each system module to a common ground.
