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.
