To gain access to the second power stage terminals, the housing covers must be removed. See Figure 5-3 on page 35.
2.2 SPMA inverter
The SPMA is a complete drive with internal rectifier and AC input line chokes (AC in to AC out). It can provide a maximum continuous output current
of 236A (400V drive). DC connections are available for use in regen and bus-parallel applications. The SPMA is available with or without a braking
IGBT fitted.
