PVP260kW Inverter
Installation and Operation Manual
Equipment Precaution/ Warning Labels
Observe all warning decals, placards and symbols posted within the inverter for safe
operation.
Disconnect Switches
The unit is equipped with both AC and DC Disconnect (power OFF) switches to stop
power conversion within the inverter unit. Before accessing the interior of the cabinet,
these switches must be in the off position. Since these disconnects only stop power
conversion within the unit, both the DC (photovoltaic array) and AC (utility grid) circuits
must be isolated in order to fully ensure the inverter is de-energized. See
2.5 De-energize/
Isolation Procedures on page 13 for information on how to perform this task.
!
DANGER
AC and DC voltages will still be present at the inverter AC and DC landing
points unless utility connection circuit breaker and PV array inputs are
disconnected.
!
DANGER
Risk of Electrical Shock. Allow five (5) minutes for internal power to dissipate
prior to entering the enclosure cabinet. Ensure all terminals are voltage free
with the use of a multimeter.
2.3 Personal Safety
Safety Zone
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).
