7. CONNECTION METHOD
To optimise transient performance, attempt to
connect the Movtecs in the “Preferred” fashion
as depicted on pages 16 and 17. This is
recommended for cable sizes between 6mm
2
and 16mm 2 . Take care not to run the protected
and unprotected wire parallel or in close
proximity.
Where this is not possible due to layout or
conductor size, use the “Non-preferred” “T”
connection method as depicted on pages 16 to
18. With this connection method, the “T” lead
should be between 6mm
2 and 16mm 2 . The
connection should be as short as practicable
(less than 100mm).
Cable sizes less than 6mm 2 should not be used
without specialist advice.
