Non-observance can result in death, personal injury or substantial property
damage.
Only a competent electrician is allowed to carry out the electrical installation.
National and local electrical safety regulations must always be followed.
The frame of the IEDs has to be carefully earthed.
Whenever changes are made in the IEDs, measures should be taken to avoid
inadvertent tripping.
The IEDs contain components which are sensitive to electrostatic discharge.
Unnecessary touching of electronic components must therefore be avoided.
