Does too little voltage (temporarily) cause damage to C-Bus components?

I have two networks.

If I need to turn the power off to the C-Bus side of things (which isn't often) I am able to switch off power to the whole of network 254 from the COMs room via a 2A circuit breaker.

With network 253 I have three power supplies in the COMs room and three powered relays in more distant locations (in other buildings) so when I power this off from the COMs room(on it's circuit breaker) I will still have 600ma of power for a network that requires around 1500ma normally.

The need to do this doesn't occur often and clearly the network won't function properly (which is fine since given I am powering them off I don't expect it to) but is there any possibility of damage to components if the voltage is below the minimum amount? Is the C-Bus hardware protected from inadequate voltage?

Thanks,

 

This will all be fine. The C-Bus units are designed to handle this sort of thing.

 

Thanks Newman.

 

it will be ok like new man said.
in asia we have a big electricity problem and c bus works very fine here.
