Retro-Fit Installations (Existing Sites); Conduit And Cable Length - CENTURION SYSTEMS D5 SMART Installation Manual

SECTION 7

7.2. Retro-fit Installations (Existing Sites)

The D5 SMART has been designed to retro-fit into most existing D3, D5, or D5-Evo
installations, with the following provisions;
• If the unit is installed with the gate in the closed position and the unit on the left-
hand side (from the inside of the property), the rack should extend at least 75mm
past the centre line of the existing pinion
• If the existing unit is mounted with the maximum clearance to the foundation plate,
the new unit will require that the rack be re-adjusted to obtain the correct mesh
between the rack and pinion, as the existing bolts will be too short
If the existing foundation plate is in a good condition, it is not necessary to replace it with
the D5 SMART Foundation Plate. However, if the existing foundation plate is corroded
or needs to be replaced for whatever reason, the D5 SMART foundation plate can
accommodate the existing footprint without the need to re-route cable conduits.
7.2.1. Retro-fitting if the Existing Foundation Plate is Unusable
Thoroughly inspect the existing
foundation plate to determine
whether or not it is fit to be reused.
A foundation plate that is corroded
or otherwise damaged should be
discarded and replaced with the D5
SMART foundation plate.
Follow the procedure found under
Section 7.1.4.2. - "Existing Concrete
Plinth".
There is an allocated slot
for existing conduit from
previous D3, D5, and
D5-Evo installations as
shown in Figure 24.

7.3. Conduit and Cable Length

Route the cables as determined in
Section 5.5 - "Cabling Requirements".
Make sure that the conduits protrude
above the concrete foundation.
The mains cables should protrude
360mm above the concrete
foundation, and all signal cables
(i.e. beams, etc.) 550mm above the
concrete foundation, as shown in
Figure 25.
