mages of the insulation or individual components present a potential lethal hazard.
• In the event of any damage to the insulation, immediately disconnect the voltage supply and initiate
the appropriate repair work.

• Before commencing your work on the electrical system, disconnect it from the mains supply and check
that it no longer carries any live voltages.
• Prior to conducting any maintenance, cleaning or repair work, disconnect the mains supply and secure
it against inadvertent switching on.
