The Penn Union SLU650 is a high-quality copper lug connector designed for reliable electrical connections. It is manufactured by Crimp Supply.
Safety Information
Always follow local electrical codes and safety regulations when working with electrical components. Improper installation can lead to electrical shock, fire, or other hazards.
- Ensure power is disconnected before installation.
- Use appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses.
- Consult a qualified electrician if you are unsure about any part of the installation process.
- Do not modify the connector.
Product Overview
The Penn Union SLU650 is a single-barrel copper lug connector, typically used for terminating electrical conductors. It features a set screw for securing the wire and a flat pad for bolt-down connections.

Setup and Installation
- Prepare the Conductor: Strip the insulation from the end of the electrical conductor to the appropriate length, ensuring that the bare wire will fully enter the lug barrel without excess insulation inside or bare wire exposed outside the barrel once secured.
- Insert the Conductor: Insert the stripped end of the conductor into the barrel of the SLU650 connector.
- Secure the Conductor: Using an appropriate tool (e.g., an Allen wrench or screwdriver, depending on the screw type), tighten the set screw on top of the lug barrel. Ensure the screw is tightened firmly to establish a secure electrical and mechanical connection. Refer to manufacturer specifications for recommended torque values if available.
- Mount the Lug: Attach the flat pad of the lug to the desired connection point using a bolt and nut (not included). Ensure the connection is tight and secure.
- Verify Connection: Double-check all connections for tightness and proper seating before restoring power.
Operating Instructions
The Penn Union SLU650 is a passive electrical connector. Once properly installed, it facilitates the electrical connection between a conductor and a terminal point. There are no operational controls or user interactions required after installation.
- Ensure the connector is not subjected to excessive mechanical stress or vibration that could loosen connections.
- Periodically inspect connections in critical applications for signs of corrosion or loosening.
Maintenance
The Penn Union SLU650 connector requires minimal maintenance. Regular inspection is recommended, especially in environments with high humidity, temperature fluctuations, or corrosive elements.
- Inspection: Visually inspect the connector and surrounding wiring for any signs of damage, corrosion, discoloration (indicating overheating), or loose connections.
- Cleaning: If necessary, gently clean the exterior of the connector with a dry, non-abrasive cloth. Ensure power is disconnected before cleaning. Do not use liquid cleaners that could leave residue or cause corrosion.
- Re-tightening: If any connections appear loose during inspection, disconnect power and carefully re-tighten the set screw and mounting bolt to the appropriate torque.
Troubleshooting
Most issues related to electrical connectors stem from improper installation or environmental factors. If an electrical circuit involving the SLU650 connector is not functioning as expected, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| No electrical continuity | Loose set screw; improperly stripped wire; corrosion; incorrect wire gauge. | Disconnect power. Re-tighten set screw. Re-strip and re-insert wire. Clean or replace corroded components. Ensure correct wire gauge for the lug. |
| Overheating at connection point | Loose connection; insufficient contact area; excessive current; corrosion. | Disconnect power. Tighten all connections. Ensure proper wire insertion. Verify current load is within specifications. Clean or replace corroded parts. |
| Physical damage to lug | Excessive force during installation; environmental impact. | Disconnect power. Replace the damaged lug with a new one. |
If troubleshooting steps do not resolve the issue, consult a qualified electrician.
