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.
