Connecting To The Electricity Source; Monitoring Leds - Waters ACQUITY CM-30S Overview And Maintenance Manual

2 Preparing and operating the CM-30S

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.
Warning:
• 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.
To connect to the electricity source:
