2.2SPECIFICATIONSSPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE
The operating times below include the activation time of a trip rated form-A output contact unless otherwise indi-
cated. FlexLogic™ operands of a given element are 4 ms faster. This should be taken into account when using
FlexLogic™ to interconnect with other protection or control elements of the relay, building FlexLogic™ equations, or
NOTE
interfacing with other IEDs or power system devices via communications or different output contacts.
