RCU mounting
The RCU is intended to be pole mounted
onto timber, steel, concrete or similar poles.
The standard RCU mounting bracket can
accommodate all these options through the
use of either bolting or strapping of the
bracket to the pole. A combination of one
bolt and a strap is also acceptable so long as
the upper restraint is bolted.
The RCU weighs approximately 33 lbs
(15 kg). The means of securing the RCU to
the pole must be suitable for this weight.
The battery should not be installed until
after the RCU is secure to the pole.
The recommended installation sequence is:
1. Mount the bracket to the pole using
either M16 galvanized bolts of grade 4.6
or higher (torque 52 lb-ft (70 Nm)) or
straps taking into account orientation
guidelines described in RCU location and
orientation section on page 28.
2. Hang the enclosure over the bracket
using the locating ears as a guide.
3. Fit the M12 cross-bolt and secure the
RCU to the pole bracket (torque 30 lb-ft
(40 Nm)).
4. Connect grounding wire as required in
Grounding section on page 35.
