Note
If your installation includes multiple chassis, wire power only to the left-most (base)
chassis.
Note
If your FB3000 does not power on, check that the polarity of the DC input voltage wiring
connections match
internal fuse and switch to protect the device from damage. Once the polarity is corrected,
the switch will reset automatically to allow for proper operation.
