EN 1175 specifies electrical requirements for the design and construction of electrical installation in self-propelled industrial trucks within the scope of ISO 5053-1, except for variable reach trucks, straddle carriers, and specific functions, parts, or systems used for the automatic operation of driverless industrial trucks. It provides control system requirements for electrical/electronic and safety-related parts to fulfil the requirements in relevant parts of the EN ISO 3691 and EN 16307 series.
EN 1175 deals with safety requirements for all electrical and electronic components of industrial trucks, including electrically actuated hydraulic and pneumatic valves. It specifies minimum performance levels required for safety functions realized by safety-related parts of control systems. It is intended to be used to avoid or minimize hazards or hazardous situations.
The standard does not deal with hazards which could occur:
— during construction,
— when operating in potentially explosive atmospheres,
— because of malfunction of non-electric safety-related parts of control systems, e.g. hydraulic and pneumatic elements like pistons, non-electric valves, pumps etc.
