Wire Power Connectors

DANGER! HIGH VOLTAGE SHOCK HAZARD. DO NOT WIRE CONNECTORS WHILE POWER IS ON.

CAUTION! BOTH POWER CONNECTORS MUST BE WIRED AND CONNECTED TO POWER SOURCES. FAILURE TO DO SO WILL DISABLE REDUNDANT SWITCHING FEATURES AND MAY INTERRUPT SERVICE.

WARNING! DO NOT APPLY POWER UNTIL TOLD TO DO SO. INCORRECT WIRING CAN DAMAGE THE ACCESS NAVIGATOR OR THE POWER SOURCE.

NOTE: The Access Navigator has redundant internal power converters, one on each 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.

2.Wire each connector to a –48V DC power source providing –42V to –58V power.

3.Follow standard practice for power wiring.

4.16 or 18 AWG insulated copper wire is recommended. (Connectors will accept 12 to 24 AWG solid 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.
