Advanced Energy
1‑2 Safety and Product Compliance Guidelines 570-1001791-05A
PERSONAL SAFETY
Ensure any personnel entering a safety zone within a four foot area around any
operating inverter wear appropriate Personal Protective Equipment (PPE) as
mandated by national, state, and local authorities.
Medical and First Aid Treatment
Personnel working in and around operating power generation equipment should be
trained in Arc Flash Hazard, Fire Extinguisher selection and use, First Aid, Cardio
Pulmonary Resuscitation (CPR), and Automated External Defibrillator (AED) use (if
available).
Safety Equipment Requirements
Authorized service personnel performing operations on this unit should have the
following minimum safety equipment available:
•Consult NFPA 70E, or applicable local standards, for PPE requirements on
switch gear operating at less than 600 V
• Electrical hazard footwear (ANSI Z41/Z85 rated)
• Lock Out Tag Out (LOTO) Kit
• Appropriate meter to verify the circuits are safely de-energized (1000 VAC and
DC rated, minimum)
• Any other equipment as applicable to your operation as required by national,
state, and local regulations

DISCONNECT SWITCH
The inverter is equipped with an AC disconnect (power OFF) to stop power
conversion within the inverter. Before accessing the interior of the cabinet, this
disconnect must be in the OFF position. Since this disconnect only stops power
conversion within the inverter, both the external (or optional inverter integrated) DC
(photovoltaic array) and AC (utility grid) circuits must be isolated in order to fully
ensure the inverter is de-energized. Wait five minutes for the inverter to de-energize
before working on the inverter.
Advanced Energy® AE 500 Inverter
570-1001791-05A Safety and Product Compliance Guidelines 1‑5
AC/DC DISCONNECT DEVICE AND OTHER REQUIREMENTS
If the optional inverter integrated AC disconnect and inverter integrated DC
subcombiner breakers were not selected, then isolated disconnect devices must be
provided for both the PV array DC connection and for the AC utility grid connection
when installing an AE inverter.
AC DISCONNECT DEVICE, OVERCURRENT PROTECTION,
AND TRANSFORMER REQUIREMENTS
If the optional inverter integrated AC disconnect was not selected, then you must
install an AC disconnect and overcurrent protection device at the AE inverter that
complies with National Electric Code ANSI/NFPA 70 and local building code
requirements, whichever is more restrictive. The AC disconnect must be rated for
480 VAC at the maximum overcurrent protection setting, typically 1.25 * IAC
maximum. You must connect the inverter to a three-phase 480 VAC grounded wye
feeder or an 800 A service. Refer to the table below.
DC DISCONNECT DEVICE AND FUSE REQUIREMENTS
If the optional DC subcombiner circuit breakers were not selected, then you must
provide a DC disconnect and fusing for each section (or sub-array) of the PV array.
The disconnect must be rated for the voltage and the current rating of the
photovoltaic array connected to the inverter. The DC disconnect installation must
comply with your national and local electrical code.
Wiring Requirements
You must meet the following requirements when wiring the AE 500 inverter:
Table 1‑1. Branch breaker size recommendations
Model 208 VAC 480 VAC 600 VAC
AE 500 N/A 800 A N/A
WIRING INFORMATION
☞ Important
You must use National Electrical Code (ANSI/NFPA 70) wiring methods.
DANGER:
Do not connect the PV negative or positive conductors to the ground bus
bars provided. The PV array is grounded through the integral GFDI.
Connecting the PV array positive or negative conductors to ground at any
other point in the system would defeat the ground fault protection circuit.
