The TOMZN TOB15-63 WiFi Smart Circuit Breaker is designed for DIN rail mounting within an electrical panel or suitable enclosure. Ensure the installation environment is dry and protected from direct sunlight and extreme temperatures.
- Ge asopọ agbara: Before starting, ensure the main power supply to the circuit is completely disconnected at the source. Use a voltagOlùdánwò e láti fìdí rẹ̀ múlẹ̀ pé kò sí agbára kankan.
- Iṣagbesori: Securely mount the circuit breaker onto a standard DIN rail in your electrical panel.
- Asopọmọra:
- Connect the incoming live (L) and neutral (N) wires to the designated input terminals (usually marked 'IN' or with arrows pointing inwards).
- Connect the outgoing live (L) and neutral (N) wires to the designated output terminals (usually marked 'OUT' or with arrows pointing outwards).
- Ensure all connections are tight and secure using the screw-type terminals. Loose connections can cause overheating and fire hazards.
