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.
