1)
PFH values are according to EN ISO 13849.
2)
In low demand mode, DC of electromechanical devices is considered as 0%, and therefore no overall DC value is claimed
in low demand mode.

ACS880-07LC/17LC/37LC drives without a main breaker
ACS880-07LC/17LC/37LC drives can be delivered without a factory-installed main breaker.
In these cases, safety data is delivered separately to the customer.
Note: Customer-installed components are not included in the safety data calculations. These
values must be added to the calculations by the customer.
￭ Safety component types
Safety component types as defined in IEC 61508-2:
• emergency stop button: type A
• safety relay(s): type A
• main contactor(s): type A
• main breaker: type A.
• FSO module: type B
• FSE module: type B
• drive STO circuit:
• frame sizes R1...R9 and drives with R1i…R7i inverter modules: type A
• frame sizes R10 and R11 and drives with R8i inverter modules: type B.
￭ Safety block diagrams
The components that are included in the safety data calculations are shown in the safety
block diagram(s). The components not included in the delivery are not included in the safety
data calculations.
The components that are included in the safety circuit are shown in the safety block diagrams
for different drive types.
