Terminal strip for connecting the líne 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 connector)
will be 8.5 mA for a line voltage of 460 V AC. Therefore, use wires with a
minimum section of 0.5 mm².
For further detail, see chapter 6. POWER LINE CONNECTION of this
manual.
Connection to an external Ballast resistor
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.

MANDATORY. The phase order in the line voltage input (2) must be exactly
the same as the one selected at the power connector (1). See figure F. H6/2.
