5. ఇన్‌స్టాలేషన్ (సెటప్)

The Circutor CEM-C30-312 MID is designed for DIN rail mounting. Ensure all safety precautions are followed before beginning installation.

5.1 మౌంటు

1. Ensure the power supply to the installation is completely disconnected.
2. Mount the meter onto a standard DIN rail (35mm) in an electrical panel.
3. Ensure adequate ventilation around the meter to prevent overheating.

5.2 వైరింగ్ కనెక్షన్లు

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:

• వాల్యూమ్tagఇ కనెక్షన్లు: వాల్యూమ్ని కనెక్ట్ చేయండిtage 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.
• పల్స్ అవుట్‌పుట్: If using the pulse output, connect it to the desired external device (e.g., PLC, BMS) according to DIN 43864.
• ఆప్టికల్ పోర్ట్: 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. ఆపరేషన్

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 డిస్ప్లే మరియు నావిగేషన్

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:

• మొత్తం క్రియాశీల శక్తి (kWh)
• Partial Active Energy (kWh)
• Total Reactive Energy (kvarh)
• తక్షణ వాల్యూమ్tage (V) per phase
• Instantaneous Current (A) per phase
• Instantaneous Active Power (kW) per phase and total
• పవర్ ఫాక్టర్ (పిఎఫ్)
• ఫ్రీక్వెన్సీ (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.
