NOTICE
Overvoltage at devices with 230-V mains connecon
An impermissible overvoltage may occur if the central supply of the N conductor is interrup-
ted if the devices are connected to a TN three-phase system.
Possible consequences: Destrucon of the device
▶
Provide for the use of isolang transformers.
NOTICE
The product contains electrostac sensive devices.
Possible consequences: Destrucon of the device
▶
Before working in the connecon area, the sta must ensure to be free of electrostac
charge.
NOTICE
Pluggable terminal strips or plug connecons
Plugging or removing the terminal strips or plug connecons during operaon may cause high
voltages and arcing.
Possible consequences: Damage of the devices
▶
Switch o device.
▶
Only plug or remove the terminal strips or plug connecons in deenergised status.
NOTICE
Use of mains lters and RFI lters in IT systems
Mains lters and RFI lters from Lenze contain components that are interconnected against

NOTICE
Overvoltage at components
In case of an earth fault in IT systems, intolerable overvoltages may occur in the plant.
Possible consequences: Destrucon of the device.
▶
Before using the inverter in the IT system, the contact screws must be removed.
▶
Posions and number of the contact screws depend on the device.
Ensure a trouble-free operaon:
Carry out the total wiring so that the separaon of the separate potenal areas
