4. INSTALLATION

WARNING:

BE AWARE THAT INSTALLATION OF THIS EQUIPMENT INCLUDES RISK OF ELECTRIC

SHOCK. NORMALLY GROUNDED CONDUCTORS MAY BE UNGROUNDED AND ENERGIZED WHEN A

GROUND FAULT IS INDICATED.

Parts Included

In addition to the micro inverters, PV modules, racking, and associated hardware,

you'll need the AUM-2000 installation kit. This kit includes the following items:

●Protective end cap

●Mounting Bracket (adapter plate)

●ACtrunk cable, 6 feet length (option)

Other Parts and Tools Required

In addition to your PV array and its associated hardware, you will need the

following parts:

●Junction box

●Sockets, wrenches for mounting hardware

Lightning Surge Suppression

Lightning does not actually need to strike the equipment or building where PV

system is installed to cause damage. Often, a strike nearby will induce voltage

spikes in the electrical grid that can damage equipment. AUM-2000 has

integrated surge protection, greater than most string inverters. However, if the

surge has sufficient energy, the protection built into the AUM-2000 can be

exceeded, and the equipment can be damaged.

Since the Austa Limited Warranty does not cover "acts of God" such as lightning

strikes, and since lightning strikes can occur anywhere, it is best practice to install

surge protection as part of any solar installation. Installation of surge protection

devices should follow vendor instructions.

Installation Procedure

WARNING:

DO NOT CONNECT AUM-2000 TO THE UTILITY GRID OR ENERGIZE THE AC CIRCUIT(S)

UNTIL YOU HAVE COMPLETED ALL OF THE INSTALLATION PROCEDURES AS DESCRIBED IN THE

FOLLOWING SECTIONS.

Installing the AU-1P20002G Micro inverter System involves several key steps:

1. Measuring service and installing the AC branch circuit junction box.

WARNING:

ONLY USE ELECTRICAL SYSTEM COMPONENTS APPROVED FOR WET LOCATIONS.

2. Attaching the AU-1P20002G Micro inverter to the racking.

3. Connecting the AU-1P20002G Micro inverter wiring harnesses.

4. Grounding the system(optional).

5. Completing the AU-1P20002G Micro inverter installation map and connecting

the PV modules.

The finished system should be similar as in the diagram. Detailed installation

steps are listed in the following section.

Step 1 - Install the AC Branch Circuit Junction Box

1. Measure service entrance conductors to confirm AC service at the site.
