6. Wiring & Connection

6.1 Connection Sockets

• Front-connecting: PF083A
• Rear-connecting: PL08

6.2 Key Connection Diagrams

6.2.1 Automatic Water Supply Control

• Power Supply: Commercial voltage (200VAC) connected via MCCB.
• Control Circuit: 24V control circuit, power supply provides 8V for electrodes.
• Wiring Notes: Connect terminal 2 to the contactor’s coil terminal; ground the common electrode E3 (longest electrode).

6.2.2 Automatic Drainage Control

• Power Supply: Commercial voltage (200VAC) connected via MCCB.
• Control Circuit: 24V control circuit, power supply provides 8V for electrodes.
• Wiring Notes: Connect terminal 3 to the contactor’s coil terminal; ground the common electrode E3 (longest electrode).

6.2.3 Three-phase Four-line Circuit Connection

• Line Voltage: 380 or 415VAC; Phase Voltage (N-R/N-S/N-T): 220 or 240VAC (compatible with 200VAC rated voltage).
• Wiring Notes: Power supply is taken from N-phase and one line phase; ground terminal 1; adjust terminal connections (terminal 2 for water supply, terminal 3 for drainage) based on application.

6.3 Operating Principles

• Water Supply Control: The pump stops when the water level reaches E1 (LED indicator ON) and starts when the water level drops below E2 (LED indicator OFF).
• Drainage Control: The pump starts when the water level reaches E1 (LED indicator ON) and stops when the water level drops below E2 (LED indicator OFF).

7. Mechanical Dimensions (Unit: mm)

• Overall Dimensions: Refer to the "Dimensions" section of the original document.
• Mounting: Use the provided PFC-N8 mounting bracket to mount the level controller to PF083A rail-mounted sockets.
• Key Dimensions: 91mm (length) × 70mm (width) (specific detailed dimensions follow the original drawing; all units are in millimeters).

8. Safety & Usage Precautions

1. Cable Selection: Use completely insulated, 600-V, 3-conductor (0.75mm²) cabtire cables; avoid exceeding the maximum recommended cable length.
2. Grounding Requirement: Ensure reliable grounding of the common electrode E3 (longest electrode) and specified terminals to prevent electrical hazards.
3. Insulation & Dielectric Strength: Comply with the specified insulation resistance and dielectric strength requirements; avoid operating in environments that may damage insulation.
4. Environmental Limits: Do not use beyond the specified operating temperature and humidity ranges to ensure stable performance.
5. Application Restriction: Not suitable for applications involving serious risk to life or property without proper system-level risk mitigation design.
6. Specification Changes: Product specifications are subject to change without notice; confirm actual specifications before use.
