5. Ho kenya
The SVP719-1-40A is designed for easy installation on a standard 35mm DIN rail. Follow these general guidelines:
- Ho Khaoha ha Motlakase: Always ensure the main power supply is completely disconnected before beginning any installation work.
- Ho hlongoa: Snap the device onto a 35mm DIN rail securely. The rail-type buckle ensures a firm fit.
- Wiring: Connect the input (IN) and output (OUT) terminals according to the wiring diagram. The terminal posts are made of copper for good conductivity. Applicable wire sizes are 16-25mm² / 6AWG-4AWG. Ensure all connections are tight and secure.
- Netefatso: After wiring, double-check all connections for correctness and ensure no loose wires.

6.3 Ts'ebetso e akaretsang
Once installed and configured, the device operates automatically. It continuously monitors voltage and current. If a parameter exceeds or falls below the set limits, the protector will instantaneously cut off the power supply to protect connected equipment. When conditions return to normal, the device will automatically re-engage the power supply after the set recovery delay time.
