Usually in electronics / electrical, the idea of 'cascade' is that the output of one device feeds the input of the next. For example, one might have 3 PSUs cascaded if the output of the first 24 V supply fed another supply that derived a 12 V rail from this, and this in turn fed another PSU to drop the voltage down to 5 V; this is a very typical arrangement — a 'series' or 'succession' of PSUs without their being wired 'in series' in the technical sense; often found within equipment, but clearly not what is being referred to here.

First of all, I would say probably not 'monté' — this is clearly referring specifically to the way they are connected up.

As for 'cascading', there is some illogicality here in the source text, and once again, I suspect a marketing person has written this tewt without sufficient technical knowledge.

It isn't possible to connect this sort of PSU literally in 'cascade' — they might be connected in series, but as F-X F points out, that would serve to increase the overall voltage, which is highly unlikely to be the desired outcome here!

They might also be connected in parallel; this would keep the voltage the same, simply tripling the current capacity available. This would make some logical sense, since if additional equipment is added, more current may be needed. However, 'cascading' is not normally the word we would sue technically for connecting in parallel. If you have some circuit or block diagrams, that might make it possible to figgure it out; otherwise, I'm afraid for safety's sake you really do need to go back and check with your customer.
