Provides information about the electrical requirements of the cabinet.

Cabinet rated power

The power supply that the cabinet can handle, as shown on the cabinet nameplate. You must enter a value with appropriate units of measure for the standard that you are using. The units of measure depend on the type of load. You can specify the default units of measure for your plant in the Data Dictionary Manager.

Power factor

Enter the ratio of active power to apparent power at 100% of the rated power and at the demand point. The power factor can have a value between 0 and 1.

Rated active power

Shows the quantity of electrical power in kW drawn from the network and that is actually converted to output power.

Rated reactive power\

Shows the quantity of reactive power in kVAR that the cabinet items draw from the network.

Rated apparent power

Shows the quantity of electrical power in kVA that represents the vector sum of the active and reactive power. This quantity is the actual power that the network needs to generate.

Supply

Select the type of supply: alternating current (AC) or direct current (DC).

Number of phases

Select the number of phases in the power supply to the load. You can select 1 or 3 phases. This property applies for an AC supply only.

Frequency (Hz)

Select the operating frequency of the load. This property applies for an AC supply only. You can define and customize the available frequencies in the Data Dictionary Manager.

Phase arrangement

Select a value to determine which of the available phases are in use for the current load, for example 2 PH + N (two phases plus neutral). This property applies for an AC supply only.

Rated voltage

Select the voltage at which the load is designed to operate. This quantity ensures electrical compatibility between the electrical supply and the equipment. It usually appears on the load nameplate. You can define and customize the available rated voltages in the Data Dictionary Manager.

Number of wires

Select the number of wires used to supply power to the load.

Override FLA calculation

Select the required option to determine whether the software uses a calculated or manually typed full load current value. If you select Calculated, the software calculates the full load current value based on values you enter on the Load Data tab; the calculated value overwrites any value that you previously entered manually. Selecting Manual enables data entry in the Full load current box, with the last calculated full load current as the starting value.

Full load current (FLA)

The electrical current, in amperes, that the load draws from the supply when operating at maximum power. The full load current usually appears on the nameplate of the load. You can select Calculated or Manual from the Override FLA calculation list to determine whether the software calculates this value or whether you enter a value manually. When the load has an attached cable, the software copies this value to the cable and uses it as a default value for sizing the cable.

Starting current

The electrical current, in amperes, that the cabinet uses for the associated equipment when starting. When the cabinet has an attached cable, the software copies this value to the cable and uses it as a default value for sizing the cable.

Coincidence factors

Allows you to enter values corresponding to the percentage utilization of the load for the selected operating mode. Also known as duty factors. Type a value between 0 and 1 for the required mode. A value of 0 corresponds to an unused load, while a value of 1 corresponds to continuous operation.

Operating mode

Select the operating mode that describes how the cabinet is used in practice in the plant. The standard available operating modes are:

Continuous

Intermittent

Standby

Spare

The coincidence factor corresponding to the selected operating mode provides a quantitative measure of the cabinet behavior in that mode.  You can customize the available operating modes in the Data Dictionary Manager.

Manage Operating Cases

Opens the Manage Operating Cases dialog where you can add, edit, or delete property values specific to various plant operating cases that exist for the current plant item.
