Power connectors
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 RST, RTS, TRS, etc.
The ground connection of the cable shield is made from the vertical plate
(A) next to the terminal strip. See figure
.
The following table shows the values for gap, tightening torque, sections
and other interesting data of the power feed-through terminal blocks:

This detail represents the termi-
nal strip for connecting the RPS-
80 power supply to mains.
MANDATORY.
As for possible high leak currents, use a protection ground
wire with a cross section of at least 10 mm² (Cu) or 16mm² (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 fu-
ses. Therefore, installing protection fuses when using RPS power supplies
does not prevent a failure of the module, but it does minimize the number of
components that may be destroyed as a result of a possible failure.
RE-
COMMENDATION
. Install fast fuses in three-phase power supply lines L1,
L2 and L3, for a higher current than the one for S6 of the RPS used. See ta-
ble
.
