3.4 Power Supply Wiring
CAUTION:The antenna cables must be properly connected to both the controller and the antenna at any
time that power is applied to the controller. Failure to properly connect the controller to the
antenna can cause damage to the unit. Connecting the controller to any antenna other than the
LRP2000 antenna can not only damage the controller, but can void your authority to operate the
LRP2000.
Loosen the terminal screws on the terminal block of the power supply and connect the spade lugs of Cable
CBL-1474 to the terminals according to Table3. Strip 1/4 inch from the opposite ends of the cable
assembly and connect to the input power terminals according to Table 3.
CAUTION:Only after all internal connections are completed should the LRP2000 power supply be
connected to the AC mains.
