Page 3: Basic - Information
Basic - Information 2 Basic - Information Safety advice Electronic equipment is not fault proof. Attention – High voltage 360-550V~, 450-550V= Shock hazard / Danger of life!! Before installation or commissioning begins, this manual must be thoroughly read and understood by the technical staff involved. The devices are electrical equipment (EB) to the power electronics for the control of power flow in electrical power systems. - Page 4 Basic - Information The user must ensure that in the event of: - device failure - incorrect operation - loss of regulation or control the axis will be safely de-activated. It must be ensured that the machines, equipment or vehicles are fitted with device independent monitoring and safety feature.
