5. Setup and Installation

Before beginning installation, ensure that all power to the circuit is disconnected at the main breaker or fuse panel.

5.1 Mounting

1. Select a suitable mounting location that is dry and protected from environmental elements, consistent with NEMA Type 1 enclosure ratings.
2. Secure the relay enclosure using appropriate fasteners through the mounting tabs.
3. Utilize the 1/2" NPT nipple for conduit connection to protect wiring.

5.2 Wiring Connections

Refer to the product label and the following guidelines for correct wiring. All wiring should be performed by a qualified electrician.

Coil Input Wiring:

• Common: White/Yellow wire.
• 24 Vac/dc Input: White/Blue wire.
• 120 Vac Input: White/Black wire.
• Connect the appropriate input voltage (24VAC/DC or 120VAC) to the corresponding coil input wire and the common wire.

Contact Output Wiring (SPDT):

• Common (COM): Yellow wire.
• Normally Open (N/O): Orange wire.
• Normally Closed (N/C): Blue wire.
• Connect the load to the desired contact configuration (N/O or N/C) and the common wire.

Ensure all connections are secure and insulated before restoring power.

6. Operation

Once properly installed and wired, the relay operates automatically based on the applied coil voltage.

• When the specified coil voltage (24VAC/DC or 120VAC) is applied to the coil input, the relay will activate.
• Upon activation, the Normally Open (N/O) contacts will close, and the Normally Closed (N/C) contacts will open.
• The integrated LED indicator will illuminate when the relay coil is energized and the relay is activated.
• When the coil voltage is removed, the relay will de-activate, returning the contacts to their original state (N/O open, N/C closed).

7. Maintenance

The RIB2401B relay is designed for reliable, long-term operation with minimal maintenance. Periodic checks can help ensure continued performance:

• Visual Inspection: Periodically inspect the relay and its wiring for any signs of physical damage, loose connections, or overheating.
• Cleaning: If necessary, gently clean the exterior of the enclosure with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Functionality Check: Verify that the LED indicator illuminates when the relay is expected to be active and extinguishes when inactive.

Always disconnect power before performing any inspection or cleaning.

8. Troubleshooting

If the relay is not functioning as expected, consider the following:

• No LED Indication:
  • Check if power is supplied to the coil input.
  • Verify that the correct voltage (24VAC/DC or 120VAC) is applied to the correct coil input wires.
  • Inspect for loose or incorrect wiring connections.
• Relay Not Switching Load:
  • Ensure the relay is activating (LED is on).
  • Check the load wiring to the COM, N/O, and N/C terminals for correct connections.
  • Verify the load current and voltage do not exceed the relay's contact ratings.
  • Test the load independently to confirm it is functional.
• Intermittent Operation:
  • Check for unstable input voltage to the coil.
  • Inspect for loose wiring connections that may cause intermittent contact.

If issues persist after troubleshooting, contact customer support or a qualified electrician.
