•
Keep away from flammable, explosive materials to avoid fire disaster.
•
The installation location should be away from areas where humidity is high or
where the inverter is in close proximity to corrosive substances.
Authorized service personnel must use insulated tools when installing or working
with this equipment.
•
PV modules shall have an IEC 61730 class A rating.
•
Never touch either the positive or negative pole of PV connecting device,
and touching both of them at the same time is strictly prohibited.
•
The unit contains capacitors that remain charged to a potentially lethal
voltage after the MAINS and PV supply has been disconnected.
•
Hazardous voltage will present for up to 5 minutes after disconnection from
power supply.
•
CAUTION-RISK of electric shock from energy stored in capacitors. Never
operate on the solar inverter couplers, the mains cables, PV cables or the PV
generator when power is applied. After switching off the PV and mains,
always wait for 5minutes to let the intermediate circuit capacitors discharge
before you unplug DC and mains couplers.
•
When accessing the internal circuit of thesolar inverter, it is very important
to wait 45 minutes before operating the power circuit or demounting the
electrolyte capacitors inside the device. Do not open the device before the
time limit since the capacitors require time to sufficiently discharge!
•
Measure the voltage between terminals UDC+ and UDC- with a multi-meter
(impedance at least 1Mohm) to ensure that the device is discharged before
beginning work (35VDC) inside the device.
PE Connection and Leakage Current
•
The end-use application shall monitor the protective conductor by residual
current operated protective device (RCD) with rated fault current Ifn≤240mA
which automatically disconnects the device in case of a fault.
•
DC differential currents are created (caused by insulation resistance and
through capacities of the PV generator). In order to prevent unwanted trigger-
ing during operation, the rated residual current of the RCD has to be min
240mA.
The device is intended to connect to a PV generator with a capacitance limit of
approx. 700nf.
