1. Pre-installation Check

Verify that the part number HBMBCAAJNEA1BBN1XG meets your project requirements. Check the installation environment: the allowable operating temperature ranges from -25°C to +70°C. Avoid locations with severe vibration, corrosive vapors, direct sunlight and excessive humidity.

Prepare required tools including insulated screwdriver, torque wrench, anti-static wrist strap and multimeter. Isolate the corresponding bay, disconnect all power supplies and fully discharge capacitors prior to wiring work. Get ready the wiring diagram, CT/VT test block (RTXP18 recommended), and shielded twisted-pair cables for communication.

2. Panel Mounting

The REM615E supports flush mounting, semi-flush mounting, 19-inch rack mounting and Combiflex frame mounting.

The cutout size for standard flush mounting is 161.5±1 mm (height) × 165.5±1 mm (width). Insert the IED housing into the panel opening, attach the mounting brackets and fasten the screws with a torque of 0.7–1 Nm. Ensure the front sealing gasket is properly seated to preserve the IP54 front protection rating. Leave adequate ventilation space around the device for heat dissipation.

Once the housing is secured, insert the removable plug-in module into the housing and raise the locking lever to fix and seal the module.

3. Wiring Procedure

Protective earth

Run a short and thick cable from the protective earth terminal to the main cabinet earth busbar. Earthing connection shall be completed first before all other wiring.

CT current inputs

Route 1A/5A CT secondary conductors to the current terminals. Install test blocks on CT circuits. Always short the CT secondary before disconnection; an open CT secondary circuit is strictly prohibited.

VT voltage inputs

Connect VT secondary circuits (100 V phase-to-phase) to voltage terminals and residual voltage terminals. The VT secondary side must be solidly grounded.

Binary inputs

Wire breaker position feedback, limit switches, interlock signals, local/remote selection and reset dry contacts to the 14 optically isolated binary inputs. These inputs accept both AC and DC wet contact signals.

Binary relay outputs

Lay cables for Form C relay outputs for trip circuits, alarm signals and status indication. Activate trip circuit supervision for critical trip loops.

RTD and 4–20mA analog inputs (optional)

Connect Pt100/Pt1000 RTD sensors and 4–20mA transmitters to the dedicated auxiliary analog terminals. The 3-wire RTD wiring method is recommended to minimize measurement errors.

Auxiliary power supply

Supply 48–250 V DC or 100–240 V AC to the power terminals. Confirm the supplied voltage falls within the rated range of this specific variant.

Communication wiring

Ethernet port (IEC61850, Modbus TCP): Use shielded CAT5e cable with single-point shield grounding.

RS485 port (Modbus RTU, IEC 60870-5-103): Apply shielded twisted pair cable in bus topology; fit a terminating resistor at the far end of the bus.

Wire IRIG-B or PTP time synchronization lines according to system design.

4. Wiring Separation Rules

Physically separate CT/VT signal cables, power cables, binary signal wires and communication cables. Communication and analog signal cables must be shielded and routed away from high-current power cables to suppress electromagnetic interference.

5. Power-on and Commissioning

Perform a thorough inspection of all wiring, terminal tightening torque, earthing connections and CT shorting status before energization. Remove CT shorting jumpers once the inspection is passed.

Switch on the auxiliary power supply and confirm the IED boots up without hardware fault alarms. Establish connection with PCM600 via the front service port or Ethernet port, then download the protection setting file. Configure protection parameters, application logic, communication addresses and time synchronization.

Carry out binary input/output tests, CT/VT injection tests and protection function verification. Check event logs, disturbance recorder records and communication connectivity to SCADA or DCS. Save and lock the settings, complete the commissioning report and close the front seal.
