Do not rely on the latching device to provide adequate security. This is only
achieved by fitting all eight bolts to the base
All mounting hardware should then be torque loaded to the values shown in the table in the
Section “Torque Loadings”.
Finally, hand tighten the HD ALT collar and secure with a padlock.
Electrical Connection
The infrastructure and signal cables are connected using standard plug couplers. To connect
them, align the keyway and lug inside the connector shells then turn the locking collar by hand
until an audible ‘click’ is detected and the two indicator spots are aligned. (The spots may be of
different colours; this is simply the preference of the manufacturer and does not affect the plug
coupler’s physical attributes)
This space intentionally blank
The Plug Couplers should connect easily and the use of handtools is discouraged.
If the coupler cannot be fully engaged by hand, there may be a fault or mismatch in
connection detail. This should be investigated as any attempt to force the connection
may result in bent or broken pins/sockets that may require replacement of either the
infrastructure cable or the signal module and cable depending on which plug coupler
is damaged
