Terminal strip to connect the Ballast resistor
The power supply is supplied from factory with a wire jumper between ter-
minals Ri and L+. This configuration of the power supply means that it
comes from the factory with its internal Ballast resistor.
However, if with this internal resistor it is not possible to dissipate enough
power (e.g. when braking), the configuration must be modified so the
power supply can work with an external ballast resistor capable of dissi-
pating that energy. Remove the wire between terminals Ri and L+ and
connect the proper external resistor between terminals Re and L+. See
the diagram in the figure.
Removing the jumper between Ri and L+ and not connecting an external
ballast resistor generates error code E215 or E304 on the display. On PS-
25B4 power supplies, the power bus will not be charged.
Here is a graphic representation of the two possible configurations:
The following table shows the values for gap, tightening torque (wire en-
try holes) and other data regarding the screw-on terminals of the ballast
resistor according to power supply model:
These power supply carry a protection against over-temperature which
triggers error E301 on the display and stops its operation when reaching
105 °C (221 °F).
