1. Introduction
The Moonrays 11604 Low Voltage Cable Connectors are designed to simplify the installation of low voltage landscape lighting systems. This product includes two durable, watertight connectors suitable for outdoor use. They facilitate quick and secure connections between landscape lights and 12, 14, or 16-gauge low voltage landscape lighting cables.
2. Product Overview
Each Moonrays 11604 connector is constructed from durable plastic, engineered to withstand outdoor conditions. The design incorporates piercing points that establish electrical contact with the main low voltage cable and the fixture wire without requiring stripping. The connectors are compatible with various wire gauges, ensuring versatility for most low voltage landscape lighting setups.

3. Safety Information
Always adhere to local electrical codes and safety guidelines when installing low voltage lighting. While these connectors are designed for low voltage applications, improper installation can still pose risks. Ensure the power to the landscape lighting system is disconnected before beginning any installation or maintenance work. Do not use these connectors with high voltage systems. Keep children and pets away from the installation area.
4. Setup and Installation
Follow these steps for proper installation of the Moonrays 11604 cable connectors:
- Prepare the Main Cable: Ensure the main low voltage landscape lighting cable (12, 14, or 16-gauge) is laid out in its desired path. Do not cut the main cable.
- Open the Connector: Unscrew the three screws on the connector and carefully separate the two halves.
- Identify Wire Slots: The connector has specific slots for different wire gauges. The main cable slot is typically a pass-through channel, while the fixture wire slot is designed for the end of the fixture wire.
- Insert Main Cable: Place the main low voltage cable into the appropriate pass-through slot (12, 14, or 16-gauge) on one half of the connector. Ensure the cable is centered over the metal piercing points.
- Insert Fixture Wire: Take the 18-gauge wire from your landscape light fixture and insert its end into the designated fixture wire slot. Ensure it is fully seated.
- Secure Wires (Crucial Step): Before reassembling, use pliers to gently but firmly squeeze the wires down onto the internal metal piercing points. This ensures a proper electrical connection. You should feel the points penetrate the wire insulation.

- Reassemble Connector: Align the two halves of the connector, ensuring all wires remain correctly seated. Press the halves together firmly.
- Tighten Screws: Reinsert and tighten the three screws to secure the connector halves. Do not overtighten, but ensure a snug fit to maintain the watertight seal.
- Test Connection: Once all connections are made, restore power to the landscape lighting system to verify that the lights are functioning correctly.
- Optional Sealing: For added moisture protection, especially in areas prone to standing water, apply a silicone sealant around the edges of the connector after installation.
5. Operating Instructions
Once properly installed, the Moonrays 11604 cable connectors facilitate the flow of low voltage electricity to your landscape lights. There are no operational controls on the connectors themselves. The operation of your landscape lighting system will depend on your transformer and any associated timers or sensors.
6. Maintenance
These connectors are designed for minimal maintenance. Periodically inspect connections for any signs of damage or corrosion. If a connector appears damaged or corroded, replace it to ensure continued reliable operation of your lighting system. Ensure the area around the connectors remains free of debris that could compromise the seal.
7. Troubleshooting
- Lights Not Working:
- Verify that the main low voltage power source is active.
- Check all connections to ensure wires are properly seated and the internal piercing points have made contact with the wire conductors. Re-squeeze with pliers if necessary.
- Inspect the fixture wire for damage.
- Ensure the light bulb in the fixture is functional.
- Intermittent Light Operation:
- This often indicates a loose or poor connection. Re-check the wire seating and piercing points within the connector.
- Inspect for signs of corrosion at the connection points.
- Connector Damage: If the plastic housing is cracked or the screws are stripped, replace the connector immediately to maintain weather resistance and electrical integrity.
