SECURITY INSTRUCTIONS

Read this manual carefully before proceeding with any handling, operation and

maintenance action. Failure to follow safety recommendations, could lead to serious

physical and material injury.

This manual should be accessible to all people involved in the installation, operation and

maintenance of the equipment.

The equipments described in this manual were designed and tested to operate within their

nominal values. Use outside this range may result in malfunction, and could cause serious

physical and material injury.

The cells and switches are equipped with safety interlocks making its use simple and

secure. Do not force them.

This equipment can be remotely controlled and contains live and mechanical parts that

move at high speed.

In the cells with circuit breakers, never perform checks on the circuit-breaker while it is

closed or with the closing springs charged. The circuit breaker must be open and the

closing springs discharged. (See the DIVAC Instruction Manual)
