Safety data values

This 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, 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 [Q2]:
• 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.
The safety data calculations are based on the following assumptions on the operation of
the main breaker [Q1]:
• 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 week.
The safety data calculations are based on the assumption that the emergency stop is used
once a month.
