8.4 Connection between modules
Power bus connection
The power bus is connected through the terminals hidden under the cover at
the bottom of each module. To do this, use 2 of the 3 plates and the washers
and nuts supplied with each module.
The tightening torque must be between 2.32.8 N·m.
The power supply module must provide the power needed by all the devices
connected to it. If this power exceeds the maximum value that the power
supply can provide, two power supplies will be required.
Assign to each of them the supply of a separate group of drives.
MANDATORY. All the modules, including the Bus Protection Module, BPM,
must be tightly joined to each other guaranteeing a good electrical contact.

If two power supplies are needed, they must be installed in separate groups.
Note. *The Bus Protection Module BPM may be mounted anywhere in
the DC BUS and whenever there is a synchronous spindle and/or an
RPS power supply.
