25. Select Main Menu > Inverters > Group Mapping .
26. Turn the inverters on by clicking the black power icon at the right end of the row.
27. Switch on the Inverter AC Output breaker on the front panel of the AMPS80 HP.
28. Check the actual Inverter AC Output by measuring voltages on the AMPS80 HP AC output terminal block
in the wiring compartment (Figure 21):
a. The voltage from Neutral to L1 / L2 / L3 is approximately 124 V. At no load, the inverter output voltage
is slightly higher than nominal.
b. The voltage from L1 to L2 is approximately 240 V for a split phase system, 208 V for 2-pole, or the
voltage from L1 to L2, L2 to L3, and L3 to L1 is approximately 208 V for a 3 phase system.
c. The voltage from AC Input L1 to AC Output L1 is less than 30 V. Similarly, the voltage between L2
input and output and L3 input and output should be less than 30 V.
Installing remaining inverters and rectifiers
29. Install the remaining inverters. The newly installed inverter modules will clone themselves to be identical
to the initial modules that were installed and set up.
30. Select: Inverters > View Live Status at the CXC GUI, and verify that all inverters are recognized as
follows:
a. At this point the inverter module numbers are likely random. Note that the largest possible inverter
number is 32, corresponding to the total number of inverter slots. Renumber the inverter modules in
some logical pattern, such as from the bottom shelf up, using Inverters > View Live Status to locate
and number each module (see Figure 32).
9 10 11 12
5 6 7 8
1 2 3 4
b. We recommend that you mark each physical inverter model with its corresponding inverter number.
To help identify a specific Inverter, click on the inverter row in the View Live Status screen and the
LEDs of that inverter will flash for a few seconds.
c. Select: Inverters > Group Mapping and verify that all inverters are mapped to the correct AC Input
Group and AC Output Group. If necessary, match the AC Input Group to the AC Output Group, as
shown in Figure 33.
d. Map inverters to DC Input Groups as discussed in section 3.6.2.
31. If the system includes the rectifier option:
a. Install one rectifier module per shelf according to the instructions in the rectifier shelf manual that
ships with the unit.
b. Select: Rectifiers > View Live Status and verify that all rectifiers are recognized.
32. Use blank housings to fill slots without modules. See Figure 34.
