2.5 Safe Access To and Replacement of Parts
2.5.1 Safety
The opening of covers or removal of parts, except those to which access can be gained by hand, is liable to expose live
parts.
The instrument must be disconnected from all voltage sources before performing any adjustment, replacement,
maintenance, or repair which requires the instrument to be opened. If repair of the opened instrument is unavoidable, it
must only be carried out by a skilled person who is aware of the hazards involved.
To guarantee safety only original spare parts must be used.
2.5.2 Access to the Units
To gain access to the units, remove the screws that secure the top cover of the instrument and lift the cover up.
