5.5 Electricity source
Most modules require a separate, grounded, power source. The ground connection in the power
outlet must be common and physically close to the module.
Warning:
To avoid electric shock, do not remove protective panels from system
modules. The components within are not user-serviceable.
Notice:
To avoid damaging the electronic components of the sample manager and the
column heater or column heater/cooler, always power-off the sample manager and
column heater/cooler before connecting or disconnecting the interconnect cable.
5.5.1 Connecting to a wall electricity source
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.
Note:
Some column modules, such as the column heater (CH-A), the column heater 30 cm
(CH-30A), and the column manager auxiliary (CM-Aux), receive their power from the sample
manager via the interconnect cable.
Recommendation:
Use a line conditioner and uninterruptible power supply (UPS) for
optimum, long-term, input-voltage stability. Contact Waters to ensure the correct selection and
size.
