Aux-5000 Auxiliary Output Unit (Combines with PI-2500 Gen2 to form PI-5000 Gen2)
The PI-5000 Gen2 is composed of the PI-2500 Gen2 and the AUX-5000 auxiliary output unit, which when combined gives the unit the capability of testing 4000 ampere breakers, with essentially the same specifications as the proven PI-4000B. The auxiliary unit is smaller than the PI-2500 Gen2, so it can also be maneuvered easily in tight spaces or lowered into shafts and manholes that would not be possible with a larger single piece unit.
The AUX-5000 enclosure is easily attached to the PI-2500 Gen2 output stabs by means of horizontal bus bars with stainless steel socket head cap bolts and sturdy nut plates. The AUX-5000 enclosure is simply rolled into place to mate with the PI-2500 test set, and then the cap screws are tightened. It is recommended to use a stubby fine pitch ratchet wrench or a pneumatic air ratchet, with an allen wrench hex bit.
The main electrical power and ground connections to the AUX- 5000 are the same twist-lock connectors as those on the PI-2500 Gen2. Power cables attached and stored in a compartment in the AUX-5000 are then connected to the PI-2500. The connectors are color-coded for proper connections to be connected with black to black and red to red.
There is also a control cable with easily twist lock quick connectors which connects from the AUX-5000 to the PI-2500 Gen2.
The output of the AUX-5000 accommodates standard breaker stabs, for continuous output of 4000 amperes. It can also be configured in series mode for a continuous output of 2000 amperes. The configuration switch on the PI-2500 Gen2 must be set to 4000 or 2000 for proper output readings.
The combined unit, known as the PI-5000, can only be used on 480 VAC.
