Introduction
Information
information
The 24V supply must be protected using a 4A slow-blow fuse, one for each supply pole.
Control connections to the Unidrive SPMC/U should be made with 0.5mm
The status relay contacts are rated for switching non-inductive loads at 250Vac 6A non-inductive, up to 4Adc if the voltage is limited to 40V or up to
400mA dc if the voltage is limited to 250Vdc. Protection from overcurrent must be provided.

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.
WARNING
Input fuses as specified must be provided.
WARNING
The Unidrive SPMC/U depends on the drive for protection.
Status outputs must be linked to the drive enable regen
drive(s) and circuit to ensure that when the rectifier indicates
a fault the motoring drive(s) are disabled.
