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-
t
ed 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.
P
ossible 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
v
oltages 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
PE.
Possible consequences: The lters may be destroyed when an earth fault occurs.
Possible consequences: Monitoring of the IT system may be triggered.
▶
Do not use mains lters and RFI lters from Lenze in IT systems.
▶
Before using the inverter in the IT system, remove the IT screws.
NOTICE
Overvoltage at components
In c
ase 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
