XtrapulsPac Installation Guide
Chapter 5 - Appendix
5. Connection of the braking resistor
In order to avoid any EMC or electrical problem, some rules must be observed:
๏‚ท heat must be evacuated,
๏‚ท shielded cable or at least twisted wires must be used,
๏‚ท wires must bear high voltage and high temperature (recommended type: UL1015, AWG 14),
๏‚ท wires must be as short as possible (max. 1 m).
5.5 - LOW OPERATING VOLTAGE
XtrapulsPac drives offer the possibility to change the operating voltage.
Thanks to this feature, XtrapulsPac drives are able to work within a wide voltage range of from 24 Vdc / 17 Vac
up to 800 V
DC
/ 480 V
AC
.
Please note that a specific operating voltage modifies the drive specifications according to the table below:

IMPORTANT
The use of XtrapulsPac drives at very low operating voltage suffers from several limitations:
- Voltages below +15 V
DC
cannot be accurately measured on the DC link.
- The capacitors bank is optimized for operation at rated voltage. The energy stored in capacitors is
proportional to the square of the voltage. At very low voltage, the storage ability of the regenerative energy is
limited. Extra storage (capacitors, battery, โ€ฆ) can be necessary to assume proper operation during high
dynamic deceleration phases.
- The detection of a braking transistor error is not active:
o Below 40 V
DC
for a Pac 230 V
o Below 80 V
DC
for a Pac 400 V.
The braking resistor MUST be mounted out of range of heat sensitive and inflammable
parts (plastic, cable sleeves, etc.).
