10. All external circuits must meet and maintain the requirements of double / reinforced
installation as stated in IEC 60364 or equivalent.
11. Additional protection must be provided to prevent accessible parts (e.g. signal circuits)
from becoming Hazardous Live if a wire or screw is accidentally loosened or freed. Ensure
all wires are secured to at least one other wire from the same circuit. The attachment
must be as close to the terminal block as possible but must not apply undue stress on
the connection. Example: Use a cable tie to secure the live and neutral wire together.
If one wire becomes loose the other wire will prevent it from touching accessible parts.
12. A disconnecting device (switch or circuit breaker) must be included in the building
installation. It must:
-
Have a rating with sufficient breaking capacity.
-
Be in close proximity to the equipment, within easy reach of the operator, but not fitted
in a position that makes it difficult to operate.
-
Disconnect all phase conductors.
-
Be marked as the disconnecting device for the product.
-
Not interrupt a protective earth conductor.
-
Not be incorporated into a mains supply cord.
-
Comply with the requirements for a disconnecting device specified in IEC 60947-1
(Specification for low-voltage switchgear and control gear
-
General rules) and
IEC 60947-3 (Switches, disconnectors, switch-disconnectors and fuse-
combination units).
