Table 3-5 SPMD 200V drive ratings (200V to 240V ±10%) based on AC supply voltage
*SPMD12X1 to 12X3 ratings apply with the rectifier docked and undocked.
**SPMD12X4 rating with the rectifier docked. The overload rating for the SPMD12X4 is only available if the ambient temperature is 35°C or lower.
***SPMD12X4 rating with the rectifier undocked. The maximum continuous output current and overload rating for the SPMD12X4 is only available if
the ambient temperature is 35°C or lower.

The Unidrive SPMD can be connected to its rectifier module in two ways, directly above the inverter (docked) or independently mounted in
different vertical planes (undocked). Changes in the flow of air mean that the ratings are different for the two mounting methods for SPMD12x4.
For details on docking, refer to section 5.6 Docking a Unidrive SPMC/U to an SPMD on page 39.

When using an SPMU a separate soft start circuit must be
provided for the DC bus. Refer to Figure 4-6 on page 30 and
section 6.5 Resistor sizing for Unidrive SPMU softstart on
page 70.

NOTE
CAUTION
The Unidrive SPMD can be connected to its rectifier module in two ways, directly above the inverter (docked) or independently mounted in
different vertical planes (undocked). Changes in the flow of air mean that the ratings are different for the two mounting methods for SPMD14x4.
For details on docking, refer to section 5.6 Docking a Unidrive SPMC/U to an SPMD on page 39.
