5.2 Cablejat
ADVERTIMENT: Ensure all power is disconnected before performing any wiring. Incorrect wiring can cause damage to the device or electrical hazards.
- Identify the 'IN' (Input) and 'OUT' (Output) terminals on the meter.
- Connect the incoming AC power supply (Live 'L' and Neutral 'N') to the 'IN' terminals.
- Connect the load (device to be monitored) to the 'OUT' terminals, ensuring Live 'L' and Neutral 'N' connections are correct.
- Tighten all terminal screws securely to prevent loose connections.
