1.3 Safety instructions
1.3.1 Applicable regulations
SVS/12 switchgear is designed in compliance with EU
safety directives.
SVS/12 switchgear satisfies:
IEC 62271-1 Common specifications for high voltage
switchgear and controlgear standards
(prHD448), for the general regulations.
IEC 60265-1 High voltage switches for rated voltages
above 1 kV and less than 52 kV
(HD355.1), as a load break switch
combination for general use.
IEC 62271-105 High voltage alternating current switch
fuse combinations (prEN62271-105), as a
load-break switch with fuses.
IEC 62271-100 High voltage alternating current circuit
breakers (prHD348), as a circuit-breaker.
IEC 62271-200 Alternating current metal enclosed
switchgear and controlgear for rated
voltages above 1 kV and up to and
including 52 kV (EN 62271-200), in the
"compartmented" version based on the
insulated connections method.
1.3.2 Safety measures
Safety measures are a combination of the safety aspects
incorporated into the design of the system, and the
precautions to be taken before and during use.
A. D
ESIGN
A number of aspects are mentioned below. These are
explained in chapters 1.1 and 4.1.
A.1 Safe

Earthed metal enclosure and full primary insulation
protect against electric shock

Mechanical interlocks prevent unauthorised switching
operations.

Continuous voltage indication

Mechanical interlocks protect access to the cable
connections for changing fuses and floor contacts

Environment-friendly materials
A.2 User-friendly

Uniform and simple control panels

Easy access to the cable connection

Sufficient space for cable termination

Easy to transport

Easy to install in the operating area
B. U
SE
This includes aspects relating to:

switchroom

personnel

execution of work

fire-fighting
B.1 Switchroom
For the construction and related aspects of switchrooms,
local regulations must be complied with.
Eaton also gives the following advice with regard to clear
spaces, escape routes and entrances:
Clear space
In front of switchgear installations or between two facing
switchgear installations there must be a clear space along
the whole length. This clear space must not be less than
1.25 m in front of the installation (1.75 m for a face-to-face
arrangement).
For the height, a clear space of at least 2 m is required
from the floor or the platform in front of the installation.
Escape routes
In front of switchgear installations or between two facing
switchgear installations there must be an escape route at
least 0.5 m wide and 2 m high along the whole length.
Escape routes must be in a straight line as far as possible.
There must be no projecting parts within these escape
routes.
The height must be measured from the floor or from the
platform in front of the switchgear.
