Terminal strip for connecting the mains voltage input
Three-phase line input taken at a point before the three single-phase RPS
chokes (one choke per phase). This connection is needed to receive the
mains line voltages and it is done through connector (2) as shown in the
next figure:
The max. current circulating through the wires (screwed into this connec-
tor) will be 8.5 mA for a mains voltage of 460 V AC (rms) Therefore, use
wires with a minimum section of 1 mm².
For further detail, see chapter 6. POWER LINE CONNECTION of this man-
ual.
Connection to an external braking resistor (Ballast)
RPS power supplies do not carry a Ballast circuit and, consequently,
FAGOR does not have external braking resistors (Ballast) associated with
them. In applications requiring a Ballast circuit, one off-the-shelf will have to
be installed.

Important note: Make sure that if the phase sequence is e.g. S-L1,T-L2,R-L3
at the power connector, it must then match the sequence set at the line voltage
connector; that is: S - L1, T-L2, R-L3 .
