The following table shows the values for gap, tightening torque (wire entry
holes) and other data regarding the screw-on terminals of the ballast
connectors according to drive model:

WARNING. On ACD/SCD/CMC 1.08/1.15 modules, if an external Ballast
resistor (for braking) is going to be connected, make sure that its Ohm value
is exactly the same as that of the internal Ballast resistor. See table T.
H3/18 which indicates this value. The rest of the compact modules have
no internal Ballast resistor; therefore, always install the external Ballast
resistor supplied by FAGOR with the unit.
The terminals (Ri, Re and L+) are used to configure the Ballast circuit
whose purpose is to dissipate the energy generated while braking the motor.
By jumpering the terminals (Ri and L+), the system is configured so as to
work with the internal resistor of the compact drive module; this configuration,
as mentioned earlier, can only be set for ACD/SCD/CMC 1.08/1.15
models.
NOTE. Never configure models ACD/SCD/CMC 1.25/2.35/2.50 and SCD
2.75 with internal Ballast resistor (jumper between Ri and L+). These
modules do not have an internal Ballast resistor. If this warning is ignored
and a (L+, Ri) configuration is used instead of (L+, Re), either
unknowingly or inadvertently, there is no risk of destroying the module,
but the power bus will not charge. Remember that pin Ri has no function
in these modules.
Up to 45 °C (113 °F), this resistor dissipates the power indicated in the
technical data table. See table T. H3/18.
All the modules carry a protection against over-temperature which issues
an error E301 when reaching 105 °C (221 °F).
