touching both of them at the same time.

The unit contains capacitors that remain charged to a potentially lethal voltage after the
MAINS , battery 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 capacitor, Never operate on the
inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when
power is applied. After switching off the PV , battery and Mains, always wait for 5minutes to
let the intermediate circuit capacitors discharge before unpluging DC ,battery inplug and
MAINS couplers.

When accessing the internal circuit of inverter, it is very important to wait 5 minutes before
operating the power circuit or demounting the electrolyte capacitors inside the device. Do not
open the device before hand 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.

Explanation
CE mark. The inverter complies with the requirements of the applicable CE
guidelines.
RCM remark.
SAA certification
Beware of hot surface.
The inverter can become hot during operation. Avoid contact during
operation.
Danger of high voltages.
Danger to life due to high voltages in the inverter!
Danger.
Risk of electric shock!
The inverter cannot be disposed of together with the household waste.
Disposal information can be found in the enclosed documentation.
Don’t work on this inverter until it is isolated from battery, mains and on-site
PV generation suppliers.
Danger to life due to high voltage.
There is residual voltage in the inverter which needs 5 min to discharge.
Wait 5 min before you open the upper lid or the DC lid.
