Note: Make sure both rubber hold- downs are attached to the clips at each end of the power supply.

The sampler controller operated on 12 V dc which is supplied by an optional ac/dc power converter and/or battery.

The power supply (or battery) is placed in the compartment located directly behind the controller. Pull the rubber hold-downs up and over the clips at each end of the power supply (or battery) to hold it in place.

The short 2-pin cable on the power supply (or battery) connects the controller receptacle labeled 12 V dc.

Batteries available from the manufacturer include a lead-acid gel battery, and nickel-cadmium (Ni-Cad) battery (Cat. No. 1416). The 120 V ac to 12 V dc power converter (Cat. No. 1440) includes a built-in lead-acid battery charger. The Power Converter (Cat. No. 1443) contains a charger for Ni-Cad batteries. 230 V ac and 12 V dc power converters (Cat.

See APPENDIX for details on batteries and battery charging.

•Check the power source to make sure that it satisfies the ac power requirements of the sampler.

•Make sure that all electrical installations and connections are in accordance with national and local electrical codes.
