Protect PV.500-MH Operating Instructions

The main assemblies of the inverter are:
 DC load interrupter switch Q4
 Inverter stack, display and control unit with communication
components
 AC filter
 Inverter output contactor K7
 Mains transformer (external)
 Mains disconnector Q26
The PV cells supply the inverter stack with DC voltage via DC load
interrupter switch Q4. The inverter stack converts this DC voltage
into a 3-phase AC voltage. A sinusoidal current is fed into the
mains via the AC filter, inverter output contactor K7 and the mains
transformer.
Risk to life due to electric shock.
Potentially fatal voltages are present at the terminals on
the equipment.
 Do not touch live parts.
Mains disconnector Q26 and the isolator in the generator connec-
tion box (GCB) are there to isolate the inverter in the event of unit
faults or when maintenance needs to be performed on the unit.
The control unit is supplied with power from the AC mains or, op-
tionally, from a second AC mains.
