This user manual does not list the locking-out procedures that must be applied. The interventions described are carried out on de-energized equipment (in the course of being installed) or locked out (non operational).
Whilst commissioning and operating the product all general safety instructions for electrical applications (protective gloves, insulating stool, etc.) must be respected, this in addition to the standard operating instructions.
All operations must be completed once started.
The durations (for completing the operations mentioned) given in the maintenance tables are purely an indication and depend on on-site conditions.
1.2 Protection equipments
Only qualified and accredited people can operate on our products. They must be equipped with all the correct protective equipment required for the task being performed.
A qualified person is one who has the skills and knowledge related to the construction, installation and operation of electrical equipment and has received safety training to recognize and avoid the hazards involved.
Except when it is imposed, the wearing of the gloves has been voluntarily limited in this manual so as to have clear visuals of the hands and operations described.

3.1 Interlocking by locks
Interlocking, using padlocks, is a necessary requirement to: Guarantee certain operational functions, - slave the switchboard to an earthing switch or line isolator, - block access.
This manual deals with the two types of padlock-type locking: - locking a function, Operational interlocking
3.2 Instructions for manoeuvres and operations
The information given in this manual is required for the production of equipment operation and manipulation requirements.
These procedures are specific to each individual installation and are produced by the customer.
The manipulation and operations requirements must be displayed on the functional units concerned.
3.3 Changes or modification to installations
CAUTION Any changes or modifications to the installations must trigger an update of the padlock interlock orders.
WARNING NEVER MODIFY OR REMOVE A FUNCTIONAL INTERLOCK
NOTICE A general interlock plan must be drawn up and updated as and when the installation is changed.
