WARNING Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
WARNING High voltage
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the device as a whole!
Insulation test
The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter devices will be dam-
aged. All necessary tests have been carried out for all concerned groups of components at the factory (test voltage 1 kV or 1.5 kV
respectively, depending on the device).
If you wish to carry out the insulation test by yourself, please test only separate groups of components.
Disconnect the compressor, the fan, the heating or the peristaltic pumps, respectively, and then carry out the insulation tests.
