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.
