3.1 Interlocking by locks

Interlocking, using padlocks, is a necessaryrequirement to:Guarantee certain operational functions,- slave the switchboard to an earthing switchor line isolator,- block access.

This manual deals with the two types ofpadlock-type locking:- locking a function,Operational interlocking

3.2 Instructions for manoeuvres and operations

The information given in this manual isrequired for the production of equipmentoperation and manipulation requirements.

These procedures are specific to eachindividual installation and are produced by thecustomer.

The manipulation and operationsrequirements must be displayed on thefunctional units concerned.

3.3 Changes or modification to installations

CAUTIONAny changes or modifications to theinstallations must trigger an update of thepadlock interlock orders.

WARNINGNEVER MODIFY OR REMOVE AFUNCTIONAL INTERLOCK

NOTICEA general interlock plan must be drawn upand updated as and when the installation ischanged.
