However, it comprises important information that must be followed for personal safety, aswell as to avoid material damage. Information is highlighted and illustrated as follows according to the degreeof danger:

! DANGERDANGER means that death or severe injury will result if the measures specified are not taken.

² Comply with all instructions, in order to avoid death or severe injuries.

! WARNINGWARNING means that death or severe injury may result if the measures specified are not taken.

² Comply with all instructions, in order to avoid death or severe injuries.

iiNOTE

Important information about the product, product handling or a certain section of the documentation whichmust be given particular attention.

Qualified Electrical Engineering Personnel

Only qualified electrical engineering personnel may commission and operate the equipment (module, device)described in this document. Qualified electrical engineering personnel in the sense of this manual are peoplewho can demonstrate technical qualifications as electrical technicians. These persons may commission,isolate, ground and label devices, systems and circuits according to the standards of safety engineering.

Proper Use

The equipment (device, module) may be used only for such applications as set out in the catalogs and thetechnical description, and only in combination with third-party equipment recommended and approved bySiemens.Problem-free and safe operation of the product depends on the following:• Proper transport

• Proper storage, setup and installation

• Proper operation and maintenance

When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If properaction is not taken, death, severe injury or property damage can result:• The equipment must be grounded at the grounding terminal before any connections are made.

• All circuit components connected to the power supply may be subject to dangerous voltage.

• Hazardous voltages may be present in equipment even after the supply voltage has been disconnected(capacitors can still be charged).

• Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting theequipment, ensure that the current-transformer circuits are short-circuited.

• The limiting values stated in the document must not be exceeded. This must also be considered duringtesting and commissioning.

The times describe the response time of a typical CFC chart at the respective task level. The maximumnumber of ticks applies to a typical load for the device based on the application template Directional time-overcurrent protection, grounded electrical power system. The maximum number can be lower in case ofextensive protection applications.The task level Measurement runs in cycles every 500 ms. All other task levels are event-triggered.In order to estimate the tick consumption of a CFC chart, you can use the following formula:

Tchart = 5 ∙ nInp + 5 ∙ nOutp + TTLev + ∑i Tint + ∑j TBlock

where:

nInp Number of indications routed as input in the CFC chartnOutp Number of indications routed as output in the CFC chartTTLev 101 Ticks in Fast Event-Triggered Level

104 Ticks in Event-Triggered Level54 Ticks in Measurement Level74 Ticks in Interlocking Level
