As shown below in figure 3, the RCU enclosure in mounted to the pole using the pole mounting
bracket. Various options for how the pole mounting bracket connects to the pole and the installation
methods are discussed in section 5.3. The RCU enclosure itself is manufactured from powder-
coated stainless steel for long service life. Material options are available at time of ordering including
304 and 316 grade stainless steel.
The RCU enclosure has a handle with internal three point locking mechanism. An external padlock
can be fitted to restrict access. The locking mechanism will accept padlocks in the size range
diameter 6-10mm shank.
On the top of the RCU enclosure is a high grade UV stabilized plastic shade hood. This shade hood
fulfils two functions:
1 Reduces the effect of enclosure heating from direct sunlight onto the top of the enclosure.
2 Provides an aperture for the short range radio in the RCU to send and receive signals to
and from the switchgear above.
At the rear of the RCU enclosure there is an earth stud and a number of apertures fitted with cable
glands to allow external wiring to access the internals of the RCU for items such as:
An LV mains or VT supply
Solar power supply
External antenna’s
