Controller card. Two power input connectors are provided and both must be wired to a –
48V DC power source. It is recommended that each Controller card be powered
independently from separate power source. That way, if a Controller card or power source
fails, the redundant Controller card is capable of powering all circuits in the Access
Navigator. If separate –48V DC power sources are not available, then both power
connectors must be wired to the same power source.
1. Open package containing 3-pin power connectors (2 ea.) (see Figure 6-23).

2. Wire each connector to a –48V DC power source providing –42V to –58V power.
3. Follow standard practice for power wiring.

or stranded wire.)
5. Ensure that no power is present on the two wires to be connected. (Remove fuse or turn off circuit
breaker at power distribution panel.)
6. Strip the two wires from the power source so that 5/16 inch of bare wire is exposed.
