8.3 Installing a pRRU
This section describes the pRRU installation process. A pRRU can be installed on a wall,
ceiling, indoor metal pole, or keel, but not on an aluminum panel or a non-standard keel.
Note the following when installing the pRRU:
The pRRU cannot be grounded. If the pRRU is grounded but the RHUB connected to this pRRU is
not, the pRRU may fail to be powered on.
A minimum distance of 50 cm must be reserved between the pRRU and the incandescent lamp.
The installation spacing between the pRRU and the temperature sensor must be greater than 50 cm.
It is good practice to install the pRRU on materials that can tolerate a temperature higher than 65°C
and have an ignition point higher than 70°C.
