1.6 Cleaning
Before cleaning the equipment ensure that all ac and dc supplies, current transformer and
voltage transformer connections are isolated to prevent any chance of an electric shock
whilst cleaning.
The equipment may be cleaned using a lint-free cloth dampened with clean water. The use
of detergents, solvents or abrasive cleaners is not recommended as they may damage the
relay’s surface and leave a conductive residue.
