5.1.1 Installation of Electrical Equipment

The installation of electrical equipment shall meet thefollowing requirements, including but not limited to:

- Electrical equipment shall be installed in accordancewith the requirements of relevant standards.

- Sufficient safe access routes and working space shallbe provided around electrical equipment. No flammable, explosive, or corrosivematerials shall be stored in the vicinity.

- Class 0 equipment shall be installed only in dry,non-conductive environments and shall not be used in damp locations or in otherplaces such as metal frameworks or conductive containers.

- For Class I equipment, exposed conductive parts ormetal frames shall be reliably connected to protective earthing, eitherdirectly or through the protective earthing contact of a properly earthed plugand socket. Appropriate measures for protection against electric shock shallalso be provided according to the environmental conditions.

- For Class II and Class III equipment, live parts shallbe separated from functional earthing parts by means of double insulation orreinforced insulation.

5.1.2 Installation of Electrical Wiring

The installation of electrical wiring shall meet thefollowing requirements, including but not limited to:

- The insulation strength, mechanical strength, andcurrent-carrying capacity of electrical wiring shall be suitable for theinstallation environment and service conditions, and the installation shallcomply with the requirements of relevant standards.

- Electrical wiring shall not be crossed, entangled, orconnected by loose or insecure joints.

- Electrical wiring shall be protected against damagecaused by external heat sources, mechanical impact, or other externalinfluences.

- Where there is a risk of electric shock, the relevantparts of electrical wiring shall be provided with physical protective measures,such as protective covers or barriers.

- Protective earthing conductors shall be connected bywelding, crimping, bolted connections, or other reliable connection methods.Twisting or hook-type connections shall not be used. The green-and-yellowbi-colour conductor in cables or wires shall be used exclusively as theprotective earthing conductor under all circumstances.

5.2.2 Operation

During the operating life cycle of electrical equipment,the following requirements shall be met, including but not limited to:

- The start-up of electrical equipment shall be suitablefor the intended operating conditions and the environment in which it is used.

- Electrical equipment shall be used within itsspecified service life. Equipment that has exceeded its service life shall bepromptly withdrawn from service, replaced, or scrapped.

- Necessary monitoring or supervisory measures shall beimplemented to prevent overload operation.

- Electrical equipment that may generate flying sparksor have a high enclosure surface temperature shall be kept away fromcombustible materials, or appropriate protective measures, such as enclosure orisolation, shall be adopted. The power supply shall be disconnected promptlyafter use.

- Electromagnetic disturbances generated by electricalequipment shall comply with the requirements of relevant standards.

5.4 Maintenance Requirements

Maintenance includes preventive maintenance, correctivemaintenance, and other maintenance activities. It shall be carried out byqualified electrical personnel or personnel who have received appropriatetraining. Maintenance personnel may be internal personnel (including on-sitetechnicians and maintenance workshop personnel) or external personnel(including personnel from the manufacturer's maintenance facilities).

After maintenance, it shall be verified that theelectrical equipment complies with the requirements for normal operation.Equipment that does not meet the required conditions shall not be put intoservice. It shall be promptly scrapped where appropriate and clearly identifiedby means of a conspicuous marking.

When electrical equipment is dismantled, the originalpower supply terminals shall be properly terminated or otherwise made safe. Noconductive part that may become energized shall be left exposed.
