Installation and Wiring Guide

6.1 Mechanical Installation

Opening requirements: The standard panel opening size is 6.5 inches wide by 10 inches high, and the tolerance must be strictly controlled. During installation, the external chassis is inserted from the front of the panel and secured with four screws.

IQ modification: For the original Eaton IQ series instrument openings, seamless replacement can be achieved by adjusting the installation frame.

6.2 Electrical Wiring

CT wiring (TB4): Strict attention must be paid to polarity and phase sequence, and the CT secondary side needs to be grounded at one point. The recommended wire specification is 14-10 AWG.

PT Wiring (TB2): Supports star or delta connections. It is important to note that the secondary side of the voltage transformer must be grounded, and the terminal VG (TB2-218) must be connected internally to the casing. It is strictly prohibited to connect phase or neutral wires.

Control power supply (TB1): Terminal 101 is the DC positive or AC live wire, and 102 is the common terminal.

Input/Output (TB1, TB2): Digital inputs need to be connected to an internal wet power supply (C In Source 205/210) through external dry contacts. The output contact capacity of the relay needs to match the load.

Communication and Interlocking (TB3): Provide INCOM communication ports (J1, J2) and regional interlocking interfaces (J3). It is recommended to use shielded twisted pair cables and wire noses at the terminals to prevent short circuits.

6.3 Grounding

The casing must be reliably grounded through a dedicated grounding terminal, with a grounding wire not less than 14 AWG. All secondary common terminals of CT and PT should also be grounded.

Programming and Settings

The setting of FP-5000 can be completed through the front panel, front panel RS-232 port (using PowerPort software), or rear INCOM communication port (using PowerNet software).

7.1 Set Group and Password

Multiple setting groups: Supports up to 4 complete protection settings, which can be switched through panel, communication, or external input to adapt to different operating modes.

Password protection: The factory default password is "0000", and the default password is accepted within the first two minutes after power on. The password consists of a combination of 4 letters and numbers, and is shared between the setting mode and the testing mode.

7.2 Main Setting Categories

System configuration: Define system frequency, phase sequence, CT/PT ratio, connection method, primary/secondary display units, etc.

Protection setting: Set the starting value, delay, curve type, and direction according to the functional group (phase overcurrent, ground overcurrent, imbalance, voltage, frequency, power, circuit breaker failure, power factor, synchronization, etc.).

System alarm: Set power, demand THD、 Alarm thresholds for circuit breaker operation times, cumulative breaking current, etc.

Input/output configuration: Map physical input points (Cin1-8) to logical functions (such as 52a, BFI, remote reset); Map the logical outputs (OG1-7) to physical relays and define logical relationships (AND/OR and NOT/OR) and contact characteristics (self hold/non hold/delayed reset).

Programmable logic: Build custom logic using 6 logic gates, 6 timers, 2 latches, and 12 locking doors to achieve complex interlocking and control strategies.

Communication settings: Set INCOM address, baud rate, and RS-232 port rate.

7.3 Save and Activate

After modifying the settings, it is necessary to save them through a confirmation prompt, otherwise the changes will be invalid. If the circuit breaker is in the closed state during storage, it may trigger the misoperation of the protective component, and caution should be exercised during operation.

Communication and Network Integration

FP-5000 provides flexible and diverse communication interfaces for easy integration into automation systems.

8.1 Communication Interface

Front panel RS-232: Used for local connection to a PC, running PowerPort software for monitoring, configuration, or firmware upgrades.

Rear INCOM port (J1): Connected to IMPACC network, supports 9600bps FSK modulation, uses shielded twisted pair cable, and has a maximum distance of 10000 feet. Centralized management can be achieved through PowerNet software.

Rear INCOM accessory bus (J2): reserved for future expansion of I/O modules.

Protocol support: INCOM protocol (compliant with IMPACC standard) and Modbus RTU protocol (optional communication board).
