2 Safety
This technical document contains detailed descriptions on the safe and
proper installation, connection, commissioning and monitoring of the prod-
uct.
▪ Read this technical file through carefully to familiarize yourself with the
product.
▪ This technical file is a part of the product.
▪ Read and observe the safety instructions provided in this chapter in partic-
ular.
▪ Observe the warnings in this technical file in order to avoid function-re-
lated dangers.
▪ The product is manufactured on the basis of state-of-the-art technology.
Nevertheless, risks to life and limb for the user or impairment of the prod-
uct and other material assets may arise in the event of improper use.
2.1 Appropriate use
The device is designed solely for use in electrical energy systems and facili-
ties. It is designed to detect and report emerging, potentially harmful trends
in the monitored equipment (e.g. transformer) in good time by measuring the
concentration of gases and moisture in the equipment's insulating oil.
The device is not designed and is not suitable for detecting rapidly develop-
ing faults and therefore is not intended to protect the equipment from such
faults (e.g. through shutdown). For this, please use safety devices that have
been designed for this purpose.
If used as intended and in compliance with the requirements and conditions
specified in this technical document as well as the warning notices contained
in this technical document and attached to the product, the product does not
pose risk of personal injury or damage to property or the environment. This
applies throughout the entire service life of the product, from delivery, instal-
lation and operation to removal and disposal.
Intended use refers to the following:
▪ Operate the product in accordance with this technical document, the
agreed-upon delivery conditions and the technical data.
▪ Ensure that any necessary work is only performed by qualified personnel.
▪ Only use the equipment included in the delivery for the intended purpose
and in accordance with the specifications of this technical document.
▪ Observe the notices in this technical document regarding electromagnetic
compatibility and the technical data.
