Safety of industrial trucks - Electrical/electronic requirements
This European Standard specifies the electrical requirements for the design and construction of the electrical installation in self-propelled industrial trucks that are within the scope of ISO 5053 1, except variable reach trucks as defined in ISO 5053 1:2015, 3.21 and 3.22, straddle carriers as defined in ISO 5053 1:2015, 3.18 and 3.19, and specific functions, parts and/or systems utilized for the automatic operation of driverless industrial trucks as defined in ISO 5053 1:2015, 3.32.
NOTE 1 Reference is made to this standard in other standards which cover the non-electrical requirements of the various industrial truck types.
NOTE 2 This document only covers the integration of the standalone equipment to the industrial trucks. Other Directives and/or standards can apply to such equipment.
NOTE 3 This standard does not cover driverless functions of industrial trucks.
The requirements of this standard are valid, when trucks are operated under the following climatic conditions:
- defined in the applicable parts of the EN ISO 3691 series and the EN 16307 series;
- relative humidity in the range 30 % to 95 % (not condensing).
This standard deals with safety requirements for all electrical components of industrial trucks, including electrically actuated hydraulic/pneumatic valves. It is intended to be used to avoid or minimize hazards or hazardous situations listed in Annex I. These situations can arise during the operation in the area of use for which it is designed and during maintenance of trucks in accordance with the specifications and instruction given by the manufacturer.
This standard does not deal with all those requirements to reduce hazards which could occur:
a) during construction;
b) for industrial trucks that are required to operate in severe conditions (e.g. in extreme climates, in freezer applications, in hazardous environments);
c) because of malfunction of not electric safety-related parts of control systems, e.g. hydraulic and pneumatic elements like pistons, not electric valves, pumps etc.
NOTE 4 The level of the defined required performance for electrical safety related control systems can be used as a guideline to determine the performance of non-electric systems.
This European Standard does not repeat all the technical rules which are state of the art and which are applicable to the materials used to build industrial trucks, for which reference can be made to EN ISO 12100.

European foreword
This document (EN 1175:2020) has been prepared by Technical Committee CEN/TC 150
“Industrial trucks - Safety”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of
an identical text or by endorsement, at the latest by January 2021, and conflicting national
standards shall be withdrawn at the latest by July 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1175-1:1998+A1:2010, EN 1175-2:1998+A1:2010 and EN 1175-
3:1998+A1:2010.
This document specifies up-to-date requirements for electric/electronic installations of industrial
trucks. Requirements are mainly based on safety functions and not only on safety related parts
and take into account exclusively electric/electronic elements. This approach significantly
increases the design details of the safety aspects, therefore Technical Committee CEN/TC 150
“Industrial trucks - Safety” has agreed on requesting an overlapping period of 24 months from the
date of publication (DAV) of this document to the date of withdrawal (DOW) of
EN 1175-1:1998+A1:2010, EN 1175-2:1998+A1:2010, EN 1175-3:1998+A1:2010, in order to
allow manufacturers to update their technical construction files.
The main changes compared to the previous EN 1175 series are:
— applicability to both internal combustion engine and electric battery driven industrial trucks;
— definition of the PL for safety functions of the control system;
r
— design specifications for safety-related parts and control systems;
— specific safety requirements for Li ion energy sources;
— updated connectors and contactors requirements;
— rules for the design of the electric/electronic assistance systems;
— new standard references.
This document has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary,
Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,

provides the electrical/electronic and safety-related parts of control system requirements for
those self-propelled industrial trucks identified above to complete the requirements in the
relevant part of the EN ISO 3691 and EN 16307 series of documents.
NOTE 1 Reference is made to this document in other standards which cover the non-electrical
requirements of the various industrial truck types.
The requirements of this document are valid when trucks are operated under the following
climatic conditions:
— defined in the applicable parts of the EN ISO 3691 series and the EN 16307 series;
— relative humidity in the range 30 % to 95 % (not condensing).
This document deals with safety requirements for all electrical and electronic components of
industrial trucks, including electrically actuated hydraulic/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
listed in Annex I. These situations can arise during the operation in the area of use for which it is
designed and during maintenance of trucks in accordance with the specifications and instruction
given by the manufacturer.
This document does not deal with hazards which could occur:
a) during construction;
b) when operating in potentially explosive atmospheres;
c) 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.
NOTE 2 The level of the defined required performance for electrical safety related control systems can
be used as a guideline to determine the performance of non-electric systems.
NOTE 3 Hazards due to penetration of water and dust are covered by the definition of PL of safety
r
functions, according to EN ISO 13849-1:2015.
