After the protective device isreset or replaced, the PLC system must continue to work normally.• It may be necessary to repair or replace the module after the presenceof output currents within a range of 2 to 20 times or temporary overloadsthat exceed the limits specified by the manufacturer (see first bulletpoint).• No fire or electric shock hazards must arise when there is an overload oftwo times I e for 5 min. The highest temperature rise in the I/O insulationmust not exceed the values specified in 4.4.2. immediately after eachoverload.
