3.3.6 Connecting the
Inverter Manager to the Voltage
Supply
Danger to life due to electric shock from touching
an ungrounded product
Touching an ungrounded product can cause a lethal
electric shock.
• Ensure that the product is integrated into the existing
overvoltage protection.
• Ground the enclosure of the product.
Procedure:
To connect the Inverter Manager to the voltage supply,
perform the following actions in the specified order.
• Connect the grounding conductor to the
Inverter Manager.
• Connect the power supply unit.
Connecting the Grounding Conductor to the
Inverter Manager
Shielded ground: The shielded ground (also called
"protected ground") is located at the pin connector for the
electrical connection in the displayed view.
Procedure:
• Ground the Inverter Manager. For this purpose,
connect the grounding conductor to the grounding
screw of the Inverter Manager. Proper grounding and
the correct cable route help limit possible interference
emissions due to electromagnetic interferences (EMI).
