Adapting the cooling unit to the respective mains
voltage

Safety

An electric shock can be fatal.
Before starting work:
► turn the power source mains switch to the "O" position
► disconnect the power source from the mains
► ensure that the power source remains disconnected from the mains until all work has
After opening the device, use a suitable measuring instrument to check that electrically
charged components (e.g. capacitors) have been discharged.
An inadequate ground conductor connection can cause serious injury or damage.
The housing screws provide a suitable ground conductor connection for earthing the hous-
ing and must NOT be replaced by any other screws that do not provide a reliable ground
conductor connection.

General

The TS 4000 MV / 5000 MV and TPS 2700 MV / 4000 MV / 5000 MV power sources can
be operated as standard at a mains voltage of 3 x 200-240V / 3 x 380-460V (+/-10%). The
mains voltage switching in the power source takes place automatically.
The cooling units are factory-configured for the following mains voltages:
FK 4000
FK 4000 R
FK 4000 Rob
FK 4000 R FC = 3 x 400 V, 50 / 60 Hz, +/-10%
FK 4000 R US = 3 x 230 / 460 V, 50 / 60 Hz, +/- 10%
The cooling units are adapted accordingly for other mains voltages with the help of an
auto-transformer.
The auto-transformer is available as an option for the FK 4000 R, FK 4000 Rob and
FK 4000 R FC cooling units.
For the FK 4000 and FK 4000 R US cooling units, the auto-transformer is fitted as stand-
ard.
