Please note the following instruction in the context of electrical
"
connection:
• Operation of the inverter is only intended for use in buildings/
property with an operating current greater than/equal to 110 A for
each phase.
• Operation of the inverter at asymmetrical systems (one system
phase grounded) is not admissible.
• The inverters may only be connected to earthed systems such as
TT,TN or IT systems.
• The mains system must be appropriately fused.
• The operation in systems with normal ELCBs is not permitted
because residual currents from the DC link may flow back into the
system via earthing without activating the ELCB.
• If you use residual current protective equipment for the mains sys­
tem side, it must be suitable for being operated in conjunction
with medium-frequency systems with a DC link and a frequency of
1000 Hz. Please use type B.
Check the applicable manufacturer data!
Comply with all applicable regulations!
• Make sure that the mains voltage is within the permitted range.
For information on inverter-specific range, refer to Section 15
from page 305 and the nameplate of the respective inverter.
The positions of the connections are indicated in Section 7.1.1 from
page 251.
Connect the PE connector at the inverter to the PE connection of the
"
mains.
In connection with the PE conductor connection, also observe the
information and specifications in the Instructions "Rexroth PSG xxxx
MF welding transformers" (refer to page 173).
Connect terminal L1 at the inverter to system phase L1.
"
Connect terminal L2 at the inverter to system phase L2.
"
Connect terminal L3 at the inverter to system phase L3.
