The half controlled thyristor rectifier can be used as an external charging module for a regen system consisting of multiple drives. The required
softstart function is built into the SPMC module as standard. An external 24V, 3A power supply is required in addition to the AC supply for the SPMC
to allow the rectifier to operate. Control wiring is required between the rectifier and drive(s) so that if the rectifier indicates a fault all drive(s) will be
disabled.

Also refer to the Unidrive SPM User Guide for further detailed information on the Unidrive SPMC mechanical and electrical installation.
• The user must provide a means of preventing live parts from being touched. A cover around the electrical connections at the top of
the inverter and the bottom of the rectifier where the cables enter is required.
• Fusing as specified must be provided.
