DANGER
Operation with ungrounded (IT) mains supplies can produce extremely dangerous
conditions
The converter must always be grounded. If the converter is not grounded correctly,
extremely dangerous conditions may arise within the inverter which could prove potentially
fatal.
The converter can only be used on TT and TN mains supplies.
DANGER
Risk of burns and fire due to high temperatures
During operation and for a short time after switching the converter off, the surfaces reach
temperatures that can inflict burns or start fires!
Before attempting to touch the surfaces of the converter, ensure that enough time is given
to allow the converter to cool down to a safe temperature to avoid personal injury.
Remove any flammable materials from around the converter to reduce the risk of fire.
WARNING
Direct current on the PE conductor
This product can cause a direct current on the PE conductor.
If the wrong type of protection device is used, then the expected protection by such a
device could fail to provide the expected protection.
If a residual current device (RCD) is used to provide protection in case of direct or indirect
contact,
only a type B RCD
may be used on the power supply side of this product.
