See chapter 5, the section regarding the “ BALLAST RESISTOR
SELECTION GUIDE ” to know whether it is necessary or not to install an
external Ballast resistor or the internal one is enough.
Resistor model
See chapter 4, section regarding “ RESISTOR MODULES ” to know which
external Ballast resistor corresponds when an external resistor is required in
an ACD/SCD/CMC 1.08/1.15 module.
Connection diagrams
Terminals (Ri, Re and L+) of the ACD/SCD/CMC 1.08/1.15 modules are used
to configure the Ballast circuit.
Jumpering the terminals (Ri and L+) makes it possible to dissipate the braking
energy in the internal resistor of the compact drive. Up to 45 °C (113 °F), this
resistor dissipates the power indicated in the technical data table. See table
T. H3/18 .
In ACD/SCD/CMC 1.08/1.15 models, remove the jumper between (Ri and L+)
and connect an external resistor between (Re and L+) for dissipating energy.
On ACD/SCD/CMC 1.25/2.35/2.50 and SCD 2.75 models, always connect the
external resistor between Re and L+.
All the modules carry a protection against over-temperature which issues an
error code E301 when reaching 105°C/221°F.

WARNING. Never connect an external resistor in parallel with the internal
Ballast resistor. Ignoring this warning may cause severe damage to the
system.
