SECURITY INSTRUCTIONS
NORMAFIX
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)
