Minimum load requirements
Table 1 lists the load requirements for all CyberDome II dome configurations.
Cable requirements
Table 2 lists the requirements for the cables that connect to the dome.
Note: When using unshielded twisted-pair cable for video and data, the wires can share the same jacket but must remain
separate twisted pairs.
CAUTION: For safety, the mounting surface, hardware, and procedure used for securing the dome must support
the weight of the dome, mount (if used), cables, and any structural or environmental vibration according
to local codes.
