3.8 Power Connections

The sampler controller operated on 12 V dc which is supplied by an optional

ac/dc power converter and/or battery.

Note: Make sure both rubber hold-

downs are attached to the clips at

each end of the power supply.

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. No. 1441) are also available but

do not come equipped with a built-in battery charger. Stand-alone, wall mount

chargers are also available. See APPENDIX for details on batteries and

battery charging.

Important: Whenever electricity is present, there is a possibility of electrical

shock. Before connecting the sampler to an ac power source, the following

safety precautions should be taken:

• 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.
