Adapting the upstream fuse /transformer options
Only cooling units with the rated operating voltage 400V / 460V can be optionally connected to a different mains
voltage.
Reconnection takes place via the supply of the primary side of the transformer.
The upstream fuse must match the changed mains voltage; see Adapting the upstream fuse.
