3.5.5 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.
The specifications for the factory settings of the transformer are
provided on the yellow connection diagram (1) on the rear side of the
unit.
UL-conformity with the following fuses:
Category "ClassCC", slow-burning.
3.5.6 Collective fault signal
Two connections are provided for connection of the collective fault signal. They are marked with the item
designation SK; see Electrical connection.
The fault signaling contact is potential-free.
Ensure that the contact is loaded with a maximum of 230V, 1 A.
