Safety data values
This safety data is valid for the default design of the safety circuit (as described in section
Safety block diagrams below). In case the final design differs 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.

•
It is used for the ordinary on and off once a week.
