Safety instructions

Dear customer, dear user,This description includes important instructions concerning the installation, function and the operation. This information is therefore an important part of the device. A non-observance can result in damage being caused or the safety of personnel and plant being impaired!

The device is only to be installed and commissioned by an electrical specialist.

If the device is to be used in processes by which a possible malfunction or incorrect operation can pose a risk to personnel and plant, corresponding safety precautions are to be taken in order to avoid this.

The general standard for the construction of switch cabinets in the machine construction industry have validity for the installation.

This document is not managed by an updating service of VSE Volumentechnik GmbH.Amendments can be made to this document without further notification; errors excepted.
