2 Security
▪ 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 to avoid function-related dan-
gers.
▪ The product is manufactured based on state-of-the-art technology. Never-
theless, danger to life and limb for the user or impairment of the product
and other material assets may arise in the event of improper use.
2.1 Intended use
The product is designed solely for use in stationary large-scale systems.
It is designed to detect and report emerging, potentially harmful trends in the
monitored equipment (e.g. transformer) in good time by measuring the con-
centration 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 file as well as the warning notices in this technical
file and attached to the product, then the product does not present any dan-
ger to people, property or the environment. This applies throughout the ser-
vice life of the product, from delivery, installation and operation to removal
and disposal.
The following is considered intended use:
▪ Operate the product in accordance with this technical document, the
agreed-upon delivery conditions and the technical data.
▪ Ensure that all necessary work is performed by qualified personnel only.
▪ Only use the devices supplied for the intended purpose and in accordance
with the specifications in this technical document.
▪ Observe the notices in this technical document regarding electromagnetic
compatibility and the technical data.
2.2 Fundamental safety instructions
To prevent accidents, malfunctions and damage as well as unacceptable ad-
verse effects on the environment, those responsible for transport, installa-
tion, operation, maintenance and disposal of the product or parts of the prod-
uct must ensure the following:

Maschinenfabrik Reinhausen GmbH 202310 4001150/12 ENMSENSE® DGA 2/3
Personal protective equipment
Loosely worn or unsuitable clothing increases the danger of becoming
trapped or caught up in rotating parts and the danger of getting caught on
protruding parts. This results in danger to life and limb.
▪ All necessary devices and personal protective equipment required for the
specific task, such as a hard hat, safety footwear, etc. must be worn. Ob-
serve the "Personal protective equipment" [►Section 2.4, Page 12] sec-
tion.
▪ Never wear damaged personal protective equipment.
▪ Never wear rings, necklaces or other jewelry.
▪ If you have long hair, wear a hairnet.

▪ Keep the work area clean and tidy.
▪ Make sure that the work area is well lit.
▪ Observe the applicable laws for accident prevention in the relevant coun-
try.
Explosion protection
Highly flammable or explosive gases, vapors and dusts can cause serious
explosions and fire.
▪ Do not install or operate the product in areas where a risk of explosion is
present.
Safety markings
Warning signs and safety information plates are safety markings on the
product. They are an important aspect of the safety concept. Safety mark-
ings are depicted and described in the chapter "Product description".
