Installation & Maintenance Guidelines

Installation

• Mount on a DIN rail and ensure the module is placed horizontally
• Use screw terminals for wiring and verify connection tightness

Wiring

• Select 115 V or 230 V input interface based on the power supply, ensuring correct phase sequence
• Connect the output terminal to the PLC power bus according to system requirements

Ventilation & Heat Dissipation

• Maintain adequate ventilation around the module and avoid stacking to prevent overheating

Status Monitoring

• Real-time check the power supply status via LED indicators or PLC monitoring functions
• Immediately inspect the input power and load if a red light is illuminated or flashing

Regular Inspection

• Examine terminal connections, screw tightness, and heat sink dust accumulation every 6–12 months

Redundancy Configuration

• For high-reliability requirements, parallel two 140CPS11420 modules to ensure continuous power supply in case of a single-unit failure
