Labelling
VITAL WARNING LABELS must be
located at eye level and on at least one of
these locations:
• Where there is the possibility of personnel
being in close proximity to the cable
• Where the downconductor terminates to
the grounding system
• At the mast base
There is a VITAL WARNING LABEL supplied in
each of the upper and lower termination kits.
If more labels are required, contact your
nearest nVent ERICO Distributor.
Structure Bonding Braid
To ensure that the upper end of the
downconductor can be adequately
electrically bonded to the structure, a
Structure Bonding Braid has been provided
at the base of the upper termination of
the downconductor. This braid is a
75
mm (
3
in.) tail which exits from under the
termination heatshrink and is supplied with
a connector to allow connection to a
6
mm
2
(
8
AWG) copper cable (as mentioned in the
following text). This must be connected to
a conductive structural point to relieve the
electrical stresses on the downconductor
and masonry surfaces.
The use of the Structure Bonding
Braid is NOT optional, and MUST
always be used.
