When the bus connectors are nearly touching, verify that the bus bars of
the AUX5000 fit just over the bus bars of the PI2500. It may be necessary to
adjust the two units slightly while pushing together. You may apply a little
weight to the PI-2500 to achieve correct alignment. Do not ram the units
together, as this may damage the bus connections.

When the holes on the vertical buss adaptors are close to the holes on the
vertical buss install the large bolts and finger tighten, tighten all the bolts.
Be sure to turn each one a little at a time until they are snug, before
torqueing them tight, to avoid jamming and galling the threads.
GENERAL TEST PROCEDURES (for both PI2500 and PI5000)
1.
Additional requirements for testing are as follows:
a)
Breakers to be tested
b)
Manufacturers' curve data
c)
Test log and/or report forms (See examples at end of section)
d)
Basic hand tools (wrench, screwdriver, etc.)
e)
Safety equipment (safety glasses, gloves, etc.)
f)
Reliable and sufficient power source
g)
Clean, spacious, and well-lit work area.
2.
The voltage selector must be set to match input voltage.
3.
Calculate KVA requirements for the source per manufacturer’s manual.
4.
Locate a suitable earth ground and connect it to the Unit with at least #6
AWG wire.
5.
Connect the Ground Integrity binding post separately to earth ground.
6.
If possible, TURN OFF power at source.
7.
Connect power source to input, using connectors supplied.
8.
Turn on power at source, if turned off in step 6 above.
9.
Input Voltage meter should indicate actual line voltage. Verify that voltage
selector is set for this voltage. Input selector error LED should light if incor-
rect.
10.
Verify that Ground Open LED is not lit. Control power cannot be turned on
if ground integrity is not sensed.
11.
Press Control Power switch. Green lamp should light, control panel should
power up to tap 1, and MAC-21 should power up. Fans should run.
