Figure 8 Disconnecting the ODU
Warning: Ensure that power is removed from the system at the PIDU to prevent damage to the ODU while
making or breaking the connection.
5.7.3 Routing the Cable
After connecting the cable to the ODU it can be routed and secured using standard cable routing and securing
techniques. When the cable is in place it can then be cut to the desired length at the PIDU prior to connection to
the PIDU.
5.7.4 Fitting A Surge Arrestor
If you have opted to fit a Surge Arrestor, this should be installed by following the manufacturers instruction. For
recommended types see Section 9 “Lightning Protection”
5.7.5 Grounding The Installation
The ODU must be properly grounded to protect against power surges. It is the user’s responsibility to install the
equipment in accordance with Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section
54 of the Canadian Electrical Code or 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. Installation of the ODU
should be done by a professional installer familiar with codes and safety practices. See Section 9 “Lightning
Protection” for recommended grounding kits.
5.7.6 Making the Connection At The PIDU
The ODU is connected to the PIDU by means of a concealed RJ45 connector. The RJ45 connection has been
placed inside the PIDU removable cover to prevent the user inadvertently plugging other equipment into the
ODU RJ45 socket.
Warning: Plugging other equipment into the ODU RJ45 socket may damage the equipment due to the non-
standard Power-over-Ethernet techniques employed. Plugging the ODU into other equipment may damage the
ODU and/or the other equipment.
Step 1: Remove the cover by squeezing the sides
and rotating away from the PIDU.
Step 2: Plug in the ODU to PIDU Cable
ensuring that it snaps home
