Waters ACQUITY RDa - Electricity Source; Connecting to a Wall Electricity Source; Connecting to a Carts Electricity Source

D.6 Electricity source
Most modules require a separate, grounded power source. Ensure that the ground connection in
the power outlet is common and physically close to the module.
Warning: To avoid electric shock, do not remove protective panels from the device.
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.
D.6.1 Connecting to a wall electricity source
Warning: To avoid electric shock, observe these precautions:
• The power cord functions as the safety disconnect device. Position the equipment
so that you can reach the power cord easily.
• 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.
• Do not replace power cords with inadequately rated power cords.
• Inspect the power cords for damage and replace them if necessary.
• Connect each module of a system to a common ground.
• Power-off and unplug a system module or stand-alone device before performing
any maintenance operation on it.
Note: Some column modules, such as the column-heater (CH-A) and the column-heater 30-cm
(CH-30A), 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.
To connect to a wall electricity source:
1. Connect the female end of the power cord to the receptacle on the rear panel of the
module.
2. Connect the male end of the power cord to a suitable grounded wall outlet.
D.6.2 Connecting to a cart's electricity source
If your system includes an optional cart, follow this procedure to connect each module to a power
source.
