Safety data values
The safety data is valid for the default design of the safety circuit described in this manual.
If the final design is different from the default and the customer has ordered safety data
calculations (P947), ABB calculates new safety data and delivers it separately to
the customer.
The safety data calculations are based on the following assumptions on the operation of
the main contactor/breaker [Qx]:
• It is switched at low load current (normal use, ~0%, AC-1).
• It is used for the emergency stop once a month.
• It is used for the ordinary on and off once a day.
