1. Understanding the Device
The Sagemcom CS 50001 is part of Sagemcom’s range of smart metering products. It is typically a:
- Static electricity meter (single or three-phase)
- Data concentrator or grid sensor
- Component in Advanced Metering Infrastructure (AMI)
The original manual often lacks detailed troubleshooting, communication protocols (DLMS/COSEM), or practical installation tips.
I can't find my Peak/Off-Peak readings
If you do not have a time-discriminated tariff (a flat rate), your meter may not be configured to separate the readings. In this case, reading 1.8.0 (Total) is the only number that matters for your bill.
Wiring Made Simple: The #1 Source of Errors
The manual provides a complex wiring diagram with 20+ terminals. Here is the "better" version.
Terminal Blocks (Standard configuration):
| Terminal | Label | Connection |
| :--- | :--- | :--- |
| 1, 2, 3 | L1, L2, L3 | Voltage inputs (Phase 1, 2, 3) |
| 4, 5, 6 | N | Neutral connection |
| 7, 8, 9 | I1 P1 – P2 | Current Transformer (CT) leg 1 |
| 10, 11, 12 | I2 P1 – P2 | Current Transformer leg 2 |
| 13, 14, 15 | I3 P1 – P2 | Current Transformer leg 3 |
| 16, 17 | COM / RS485 | Modbus communication (A / B) |
| 18, 19 | Pulse Output | For external monitoring |
Better Tip #2: The "CT Polarity" rule.
Half of all "meter not working" complaints come from reversed CTs. The manual mentions it, but here is the golden rule: P1 (Line side of CT) faces the grid. P2 (Load side) goes to the meter. If your reading is negative or zero under load, swap the wires on terminals 7-8.
Better Tip #3: Voltage before Current.
Always wire the voltage (terminals 1-6) FIRST. The meter needs power to initialize before it reads the CTs. If you wire CTs first, you risk magnetic saturation and inaccurate readings.
Quick-Start User Manual
Technical Specifications (For Installers)
If you are looking for the manual to install or troubleshoot the device, here are the standard technical details:
- Reference Standard: IEC 62053-21 (Class 1 or 2 accuracy).
- Voltage: 230V AC (± 20%).
- Current (In): Usually 5(60)A or 10(80)A depending on the specific sub-model.
- Installation:
- Mount on a DIN rail (35mm).
- Wiring follows standard Single Phase configuration: L (Line) IN, N (Neutral) IN, then L OUT, N OUT to the load.
- Warning: Incorrect wiring can damage the meter.
- Impulse Constant: Indicates the LED flash rate (e.g., 1000 imp/kWh) for testing accuracy.
3. Emergency Credit (If applicable)
Some Sagemcom meters allow for a small amount of "emergency credit" to be activated so you aren't left without power immediately.
- Activation: Usually requires pressing a button on the front panel or inserting a specific token. Check the specific sticker on your device for this feature.
