A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are
used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure
that 1/3 space inside the pipes must be vacant.
The point at which an Ethernet cable is bundled must be spaced 400 mm or less from the
Ethernet port on a pRRU.
For the pRRU3902 used in the elevator engine room on the rooftop, generator set for the
