4.2 Mounting
Mount the NEMA enclosure securely to a wall or suitable surface using appropriate fasteners. Ensure adequate ventilation around the unit.
4.3 Wiring Connections
The unit features a barrier strip accessible through knock-outs for hardwiring power input and output connections. Follow these steps:
- Select appropriate knock-outs for incoming and outgoing power cables.
- Route the 120V AC input power cable to the designated input terminals on the barrier strip.
- Route the output power cable(s) for the protected equipment to the designated output terminals.
- Ensure all connections are secure and properly torqued according to electrical code requirements.
- Verify correct polarity (Line, Neutral, Ground) for all connections.
4.4 Remote Turn-On Connection
The SX20 NE/RT supports remote turn-on and turn-off. A separate terminal block within the enclosure is provided for this functionality. Connect a contact closure or an applied DC voltage source to activate the remote control feature. Refer to the wiring diagram provided with the unit for specific terminal assignments.
5. Operating Instructions
Once installed and wired, the SurgeX SX20 NE/RT operates automatically to protect connected equipment.
5.1 Indicator Lights
The front panel features two indicator lights:
- REMOTE (Yellow): This indicator illuminates when the unit is in remote control mode and is awaiting a signal for turn-on or turn-off.
- SELF-TEST (Green): This indicator illuminates when the unit has successfully completed its internal self-test and is operating normally. If this light is off, it may indicate a fault or power issue.
5.2 Self-Test Function
The unit performs an automatic self-test upon power-up and continuously monitors its internal components. The green SELF-TEST indicator confirms proper operation. If this light is not illuminated, consult the troubleshooting section.
6. Maintenance
The SurgeX SX20 NE/RT requires minimal maintenance. Periodically inspect the unit and its connections for any signs of wear, damage, or loose wiring. Ensure the enclosure remains free of dust and debris. Do not use liquid cleaners directly on the unit. No internal user-serviceable parts are present.
7. Troubleshooting
Refer to the table below for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to connected equipment. | No input power; tripped circuit breaker; faulty wiring. | Check main power supply; reset circuit breaker; verify all wiring connections. |
