OPERATING MANUAL

Explosion-proof components

Additional operating manual for drives the comply with the requirements of the Directive 94/9/EC. As a supplement to the operating manuals for the drives: TW63; W191; TW130; TW160; W263B; W332B this booklet contains important measures, regulations, as well as information where implementation and compliance are a prerequisite for meeting the fundamental safety and health requirements of the Directive 94/9/EC. Basic principles of explosion protection: Directive 94/9/EC specifies the explosion protection for devices and protection systems. It is restricted to the manufacture and marketing of safe products that are to be deployed in zones where there is a danger of explosion. The supplementary Directive 1999/92/EC is addressed to the operators of installations in areas where there is a danger of explosion and it regulates the safety of persons during installation, operation and maintenance. The above directives are the basis of the ATEX guidelines.

OPERATING MANUAL 1. SAFETY

1.2 General safety instructions The safety instructions serve to protect persons and property against injury of damage and dangers that result from improper use, incorrect operation, inadequate maintenance or other inappropriate actions in the area where there is a danger of explosion. This operating manual contains important supplementary details and measures, as well as regulations, where the implementation and adherence are requirements for ensuring protection in line with Directive 94/9/EC. It may only be used in conjunction with the operating manual delivered with the drive. All laws and regulation for elevator systems as well as accident prevention regulations must be known and complied with. Personnel requirements All work on the drives may only be executed by skilled, trained personnel. For work on explosion-proof drives, additional training and knowledge regarding explosion protection are required. For example, personnel must be familiar with the relevant regulations and rules for the installation, handling and operation of explosion-proof installations. Verification of the required training and corresponding experience must be provided.

Note: the work is to be checked regularly by a person responsible who is familiar with the local circumstances and the installation and has the corresponding technical knowledge of explosion protection. Informal notes on the safety measures The operating manual is to be kept permanently at the usage site of the installation. Complementary to the operating manual, the generally applicable and local regulations for

accident prevention and environmental protection are to be provided and complied with. Legally prescribed safety instructions are to be provided for the users at clearly visible

positions. Keep all safety and hazard warnings on the installation in a legible condition. General safety instructions for operation in the Ex zone: Only assemblies or devices that are approved for Ex operation may be installed and operated. The drive, motor and additional electrical equipment may only be operated in the Ex-protected area if the described requirements, regulations and measures are complied with.

NB: in the case of an explosive gas mixture or dust concentration in conjunction with hot surfaces, open live connections, friction of moving parts, switching, grinding and impact sparks, severe or even fatal injury can occur. Dust deposits: to reduce the risk of dust explosions, the installation operator must ensure that a possible dust deposit does not exceed a maximum thickness of 5 mm in accordance with EN50281-1-2.

OPERATING MANUAL 1. SAFETY

Ambient conditions: it must be ensured that the drive is adequately ventilated and that there is no external heat transfer. If additional protective hoods are deployed, a risk analysis must verify that no ignition sources can arise, e.g. impact sparks due to grinding. In shaft areas with aggressive chemical vapours and gas, protection is to be provided and precautions taken against electrochemical corrosion. The entire area of the drive is to be checked to ensure that no ignition sources can arise, e.g. impact sparks due to grinding. Important safety instructions for assembly, maintenance and repair tasks for explosion-proof installations: Due to the special hazardous situation that makes explosion protection necessary, special regulations apply and additional precautionary measures are to be taken, even for maintenance, installation and repair work. This includes strict adherence to a work approval system. Work approval system: All work to be carried out in the area where there is a danger of explosion or in its vicinity that could lead to an explosion is to be approved before the work starts by the operator or a person responsible in writing in the form of an 'approval note'. The approval of work in writing should contain the following details: day, work area, persons involved, point of contact responsible, forecast duration of the measures, as well as a short description of the protection measures to be taken. If an activity lasts a number of days, a new approval note is to be issued for each additional day. Before the start of installation, maintenance or repair work, an approval note is to be obtained for the area concerned. It is to be ensured that all the required protection measures have been taken and that in the work area the presence of dangerous explosive atmosphere can be excluded. This is to be ensured for entire duration of the work and, if required, also beyond. After completion of the work, the safety of the installation is to be checked before start-up. The explosion protection measures required for normal oper
