1.3. Safety Notes

Read this manual carefully and completely: use of the protection releases should be reserved to qualified and expert personnel only.
WARNING: this symbol highlights information about operations, actions or circumstances that can cause injuries
to the personnel, damage to the protection release or economic losses.
You must assume that safe usage is impossible if:
1. The protection release shows visible signs of damage.
2. The protection release does not function (e.g. with autotest or by means of the trip test unit).
3. The release has been damaged during transport.
The protection release must be put out of service to prevent accidental use.
WARNING: Prior to servicing and/or replacing, the circuit-breaker must be open.
Also remember to disconnect all power supplies connected.
