Installation
2.7 Inverter Notifi cation Requirements
When an inverter is installed in a building, facility or structure, standard safety practices require a
label or plaque be present. This label/plaque is required to be readily visible and provide information
that informs personnel to the location of all electrical system disconnects. This is to ensure all
power to a building is quickly located and shut down in an emergency. There are also specifi c
requirements for this label/plaque depending on the inverter application, they are as follows:
• Facilities with Standalone Systems – Any building, facility, or structure with a photovoltaic
power system that is not connected to a utility service source and is a standalone system, must
have a permanent plaque or directory installed on the exterior of the building or structure at
a readily visible location acceptable to the Authority Having Jurisdiction (AHJ). The plaque or
directory must provide the location of system disconnecting means, and include information
regarding whether the structure contains a standalone electrical power system.
• Facilities with Utility Services and PV Systems – Buildings, facilities, or structures with
both utility service and a photovoltaic system must have a permanent plaque or directory
providing the location of the service disconnecting means and the photovoltaic system
disconnecting means, if they are not located at the same location.
2.7.1 Inverter Warning Label
A warning label as shown in Figure 2-18 is provided to inform all personnel that an inverter is
installed in your electrical system. Affi x this label in a clearly visible location at the electrical panel
that is being powered by the inverter. This is because it might be falsely assumed that the panel is
no longer “hot” after the AC power has been shut off, when power may actually still be available
due to the inverter automatically powering the panel.
This electrical system is equipped with an Automatic
Generator Starting (AGS) device and/or an inverter.
Disconnect all AC and DC power to the AGS and/or
inverter before performing any service to the electrical
system. Failure to do so can result in shock causing
serious injury or death.

2.8 Final Inspection
1. Verify all cables/conduit runs are secured with wire ties or other non-conductive fasteners to
prevent chafi ng or damage from movement and vibration.
2. Verify strain reliefs or grommets are in place to prevent damage to the wiring or conduit where
it passes through walls, bulkheads, or other openings.
3. Verify all AC connections are correct and torqued to a maximum of 1.8 N-m (16 in lbf).
4. Replace the covers on the main electrical/distribution panel.
5. Replace the chassis access cover.
6. Verify the inverter’s front panel switch is in the OFF position.
Info: If required by code, have the installation inspected by an electrical inspector.
