Working methods for electrical engineering work
Basically, a distinction is made between three working methods for working on electrical systems:
Method 1 Work in a de-energised condition (disconnected)
Method 2 Work in the vicinity of live parts
–
Distance 300 mm min.
Method 3 Work on live parts
–
AuS1: Simple routine work, e. g. measurements.
=> No specialised personnel or personal protective equipment (PPE) required.
– AuS2: Work such as installing hw+
=> Specialised personnel and personal protective equipment PPE mandatory.
Service index definition
The service index summarizes the user requirements with regard to the three properties of operation,
maintenance and expansion in a three-digit numerical code. Three steps are defined for each of the
three properties.
Operation Maintenance Expansion
– Presetting
– Interlocking
– Adjustment
– Inspection
– Cleaning
– Restoring the operating state
– Extension
– Addition
– Modifications
Step 1 IS = 1xx
Disconnection of the entire
switchgear.
IS = x1x
Disconnection of the entire
switchgear.
IS = xx1
Disconnection of the entire
switchgear.
Step 2 IS = 2xx
Switching off the functional unit
concerned (power and auxiliary
circuits).
IS = x2x
Switching off the functional unit
concerned.
Connections must be
disconnected.
IS = xx2
Switching off the functional unit
concerned.
Expansion limited to reserve
spaces.
Step 3 IS = 3xx
Switching off the power of the
functional unit concerned
(auxiliary circuits remain in
contact).
IS = x3x
Switching off the power of the
functional unit concerned.
Connections do not need to be
disconnected.
IS = xx3
Switching off the power of the
functional unit concerned.
Retrofitting possible.
04.02 Electrical connection
Type of electrical connection according to EN 61439
The user can specify the electrical connection of functional units within the switchgear combination. A
three-digit code identifies the type of electrical connection of the functional unit:
–
1st letter: Feeding the main circuit to the functional unit
– 2nd letter: Outlet of the main power circuit from the functional unit
– 3rd letter: Connection of auxiliary power circuits
The following letters stand for the relevant type of connection:
–
F: For fixed connections,
– D: For releasable connections,
– W: For guided connections.
A functional unit with the code allocation FFD has, for example, fixed feed connections, fixed outlet
connections and releasable auxiliary circuits.
