2 Safety
This technical file contains detailed descriptions on the safe and proper in-
stallation, connection, commissioning and monitoring of the product.
▪ 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 of the user or impairment of the prod-
uct and other material assets may occur during use due to function-re-
lated dangers.
2.1 Appropriate use
The protective relay protects the on-load tap-changer and the transformer
when a malfunction occurs in the diverter switch oil compartment or selector
switch oil compartment. The product is designed solely for use in electrical
energy systems and facilities. 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 danger to people, property or the environment.
This applies throughout service life of the product, from delivery to installa-
tion and operation through to disassembly and disposal.
The following is considered appropriate use:
▪ Use the product only with the on-load tap-changer and transformer speci-
fied in the order.
▪ The serial numbers of on-load tap-changer and on-load tap-changer ac-
cessories (drive, drive shaft, bevel gear, protective relay, etc.) must match
if the on-load tap-changer and on-load tap-changer accessories are sup-
plied as a set for one order.
▪ Operate the product in accordance with this provided technical file, the
agreed delivery conditions and technical data.
▪ Ensure that all necessary work is performed by qualified personnel only.
▪ Only use the equipment and special tools included in delivery for the in-
tended purpose and in accordance with the specifications of this technical
file.
2.2 Fundamental safety instructions
To prevent accidents, disruptions 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:
2 Safety
Maschinenfabrik Reinhausen GmbH 201810 1800059/09 ENRS
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 increases the 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 section "Personal protective equipment" [►Section 2.4, Page
12].
▪ Never wear damaged personal protective equipment.
▪ Never wear rings, necklaces, or other jewelry.
▪ If you have long hair, wear a hairnet.
Work area
Untidy and poorly lit work areas can lead to accidents.
▪ 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.
Protection against electric shock
If the terminal box cover of the protective relay hangs from the wire on the
side of the enclosure, this can lead to damage to the wires. This poses a
danger to life and limb.
▪ Always remove the terminal box cover with wire from the protective relay
for any work which involves opening the protective relay.
▪ Remove the slotted head screw for potential tie-in and remove the termi-
nal box cover with wire.
Working during operation
The product may only be operated in a sound, operational condition. Other-
wise it poses a danger to life and limb.
▪ Regularly check the operational reliability of safety equipment.
▪ Comply with the inspection work, maintenance work and maintenance in-
tervals described in this technical file.
Explosion protection
Highly flammable or explosive gases, vapors and dusts can cause serious
explosions and fire. This increases the danger to life and limb.
▪ Do not install, operate or perform maintenance work on the product in ar-
eas where a risk of explosion is present.
