The switchgear corresponds to the relevant laws, prescriptions and standards applicable at
the time of delivery. If correctly used, it provides a high degree of safety by means of logical
mechanical interlocks and shockproof metal enclosure of live parts.
Independently of the safety instructions given in these operating instructions, the local laws,
ordinances, guidelines and standards for operation of electrical equipment as well as for labor,
health and environmental protection apply.
The switchgear operator or owner must keep the technical documents supplied with
the switchgear throughout the entire service life, and keep them up-to-date in case of
modifications of the switchgear.
The Five Safety Rules of Electrical Engineering must be complied with during operation of
the products and components described in these operating instructions:
• Isolate.
• Secure against reclosing.
• Verify safe isolation from supply.
• Earth and short-circuit.
• Cover or barrier adjacent live parts.
If hazardous substances are required to perform the work, the relevant safety data sheets and
