5. 설치(Setup)
The Circutor CEM-C30-312 MID is designed for DIN rail mounting. Ensure all safety precautions are followed before beginning installation.
5.1 장착
- Ensure the power supply to the installation is completely disconnected.
- Mount the meter onto a standard DIN rail (35mm) in an electrical panel.
- Ensure adequate ventilation around the meter to prevent overheating.
5.2 배선 연결
The CEM-C30-312 MID uses indirect measurement, requiring external current transformers (CTs). Refer to the wiring diagram provided with your current transformers and the meter for precise connections. Below is a general guide:
- 권tage 연결: 볼륨을 연결하세요tage inputs (L1, L2, L3, N) to the corresponding phases and neutral of the electrical system.
- Current Transformer Connections: Connect the secondary outputs of the current transformers (e.g., S1, S2) for each phase to the meter's current input terminals. Ensure correct polarity.
- 펄스 출력: If using the pulse output, connect it to the desired external device (e.g., PLC, BMS) according to DIN 43864.
- 광 포트 : The lateral optical port is for connecting the optional CEM-M communication module.

Important: Incorrect wiring can lead to inaccurate readings or damage to the meter. Always double-check all connections before restoring power.
6. 운영
Once installed and powered, the CEM-C30-312 MID will begin measuring electrical energy. The meter's operation is primarily managed through its LCD display and two control buttons.
6.1 디스플레이 및 탐색
The 7-digit LCD display shows various electrical parameters in a rotating sequence. Use the control buttons to manually cycle through the available screens or access specific functions.
- Button 1 (Unsealable): Typically used for navigating through display screens and confirming selections.
- Button 2 (Sealable): Often used for resetting partial counters or accessing advanced settings. This button is typically sealed after commissioning to prevent unauthorized resets.
Commonly displayed parameters include:
- 총 유효 에너지(kWh)
- Partial Active Energy (kWh)
- Total Reactive Energy (kvarh)
- 순간 볼륨tage (V) per phase
- Instantaneous Current (A) per phase
- Instantaneous Active Power (kW) per phase and total
- 역률 (PF)
- 주파수(Hz)
6.2 Resetting Partial Counter
To reset the partial energy counter, press and hold the designated (sealable) button for a few seconds until the display confirms the reset. This function is typically protected to prevent accidental data loss.
