This presents the danger of severe burns to hands and arms.
Installation and maintenance work should only be carried out when the
system is cold.
The equipment must only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in electrical
engineering, the use and application of safety equipment in accordance with
regulations concerning electrical safety systems, and first aid & accident
prevention – have achieved a recognised level of competence appropriate to the
installation and commissioning of this device.
