Grounding the installation
Install the equipment in accordance with Section 810 of the National Electric Code,
ANSI/NFPA No.70-1984 or Section 54 of the National Electrical Code in the country of
installation. These codes describe correct installation procedures for grounding the
outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and
connection requirements for grounding electrodes. Motorola recommends that
installation of the outdoor unit be contracted to a professional installer.
Grounding the ODU
The Outdoor Unit (ODU) must be properly grounded to protect against power surges.
Additional grounding points
If the ODU is installed on a metal mast or tower, the screen of the supported Superior
Essex cable must be bonded to the tower at the top and bottom ends. Additional
grounding at intermediate points of the cable may be required if the cable is longer
than 15m (50 feet).
To ground the cable, follow the procedure described in Grounding the drop cable to a
metal tower or m
ast on page 5-11.
Connecting the PIDU to the ODU cable
Perform this task to connect the PIDU to the drop cable from the ODU.
The drop cable from the ODU is connected to the PIDU Plus by means of a concealed
RJ45 socket. The RJ45 socket has been placed inside the PIDU Plus hinged cover to
prevent the user from inadvertently plugging other equipment into the ODU RJ45
socket.
CAUTION
Plugging other equipment into the ODU RJ45 socket may damage the
equipment due to the non-standard techniques employed to inject DC power
into the 1000BaseT connection between the PIDU Plus and the ODU.
Plugging the ODU into other equipment may damage the ODU and/or the
other equipment.
To connect the PIDU Plus port of the ODU to the drop cable, proceed as follows:
