2.4 Cleaning
Warning: Before cleaning the IED, ensure that all AC and DC supplies and transformer
connections are isolated to prevent any chance of an electric shock while
cleaning.
Only clean the equipment with a lint-free cloth dampened with clean water. Do not use detergents,
solvents or abrasive cleaners as they may damage the product's surfaces and leave a conductive
residue.
