The precautions for the use of aluminum electrolytic capacitors are:

(1) There is a danger of electric shock by directly touching the terminals of the capacitor.

(2) Do not short-circuit between capacitor terminals with conductors. In addition, the capacitors should not be exposed to conductive solutions such as aqueous solutions of acids or alkalis.

(3) Confirm that the installation environment of the equipment with capacitors is not one of the following environments.

① Places that are directly splashed with water, places with high temperature and high humidity, and places that are prone to condensation.

②The place where the oil is directly splashed and the place full of oil mist.

③ Places where salt water is directly splashed, places with high temperature and high humidity, and places prone to condensation.

④ Places filled with acidic organic gases (hydrogen sulfide, sulfurous acid, nitrous acid, chlorine, bromine, and methyl bromide).

⑤ Places filled with alkaline or other toxic gases (ammonia, etc.).

⑥ Places where acidic and alkaline solvents are splashed.

⑦Condensation environment may cause the jacket to shrink, swell, or rupture, so please check it thoroughly before use. In addition, when dew condensation occurs due to sudden changes in temperature, high temperature and high humidity tests, etc., the same abnormality of the jacket may also occur.
