1. Introduction
Even if the unit seems to be in stand by status, switch it OFF before operating on
circuit breakers. It may happen that the unit would operate the circuit breakers without
warning.

1.3 Safety notes
If there are doubts about safety use, the unit must put out of service.
The automatic transfer switch ATS022 must be prevented from operating the circuit breaker before
accessing the circuit breakers
performing maintenance on circuit breakers or any electrical circuits powered by them
performing any other operations where opening/closing the circuit breakers could be dangerous
During maintenance, it is advisable to lock the circuit breaker mechanically to the open position
Safe use is not possible if:
1. The unit has been damaged during transport
2. The unit shows visible signs of damage
3. The unit does not work
4. The unit has been stored for a long period
