Terminal strip for mains connection
This connector may be used to connect the power supply to mains. When
connecting the power suppliy to mains, the phases may be connected in
any order L1-L2-L3, L1-L3-L2, L3-L1-L2, etc.

Terminal strip for connection to mains.
The ground connection of the cable shield is made from the vertical plate (A)
next to the terminal strip. See figure F. H2/40
The following table shows the values for gap, tightening torque, sections
and other interesting data of the power feed-through terminal blocks:

MANDATORY. As for possible high leak currents, use a protection ground
wire with a cross section of at least 10 mm² (Cu) or 16 mm² (Al) or two
protection ground wires with the same cross section as that of the wires
connected to the power supply terminals. Comply with local regulations on
grounding.
INFORMATION. IGBT components cannot actually be protected with fuses.
Therefore, installing protection fuses when using RPS power supplies does
not prevent a failure of the module, but it does minimize the number of
i
components that may be destroyed as a result of a possible failure.
RECOMMENDATION.
L2 and L3, for a higher current than the one for S6 of the RPS used. See
table T. H6/3.
The L1-L2-L3 phases may be connected
in any sequence at the power connector.
Important note. Make sure that the phase sequence
T3
matches the one at the line voltage input connector.
