Notice
• The nominal cross-sectional area of the wires shall not less than 1.5mm
2
. Conductors
identified by the colour combination green/yellow shall only be used for grounding
conductors.
• The wires shall provide non-detachable lining or non-detachable bushing.
• The wires shall be protected so that they do not come into contact with hot surface,
wet, or significant amounts of ultraviolet radiation except the wires are suitable for the
conditions.
