4. Setup

4.1 Installazzjoni Mekkanika

1. Ensure all power is disconnected at the main breaker.
2. Mount the TOB1S-63 circuit breaker onto a standard 35mm DIN rail by engaging the clips on the back of the device.

4.2 Wiring Elettriku

The TOB1S-63 is a 3P+N device. Connect the incoming power supply to the 'Power' terminals and the load to the 'Load' terminals as indicated on the device.

• Connect the three phase lines (L1, L2, L3) and the neutral line (N) to the respective 'Power' input terminals.
• Connect the corresponding load lines (L1, L2, L3, N) to the 'Load' output terminals.
• Ensure all screw-type terminals are tightened securely to prevent loose connections and arcing.

4.3 WiFi Network Connection (TUYA Smartlife App)

1. Download the 'TUYA Smartlife' app from your smartphone's app store.
2. Irreġistra jew idħol fil-kont Smartlife tiegħek.
3. Ensure the circuit breaker is powered ON. The 'Signal' indicator light should be blinking. If not, press and hold the 'Press 10s network' button until it blinks rapidly.
4. In the Smartlife app, tap '+' to add a device. Select 'Electrical' > 'Circuit Breaker (Wi-Fi)'.
5. Follow the on-screen instructions to connect the device to your 2.4GHz WiFi network.
6. Once connected, the 'Signal' indicator will become solid.

4.4 RS485 Modbus Connection (Optional)

For RS485 Modbus communication, connect the A and B terminals of the circuit breaker to your Modbus network. Refer to the Modbus protocol documentation for specific register addresses and communication parameters.

5. Istruzzjonijiet Operattivi

5.1 Operazzjoni manwali

To manually turn the circuit breaker ON or OFF, use the red toggle switches on the front panel. Push up for ON, push down for OFF.

5.2 Smartlife App Operation

Once connected to the Smartlife app, you can:

• Remotely turn the circuit breaker ON/OFF.
• Set schedules or timers for automatic operation.
• Monitor real-time current, voltage, u l-konsum tal-enerġija.
• Adjust protection parameters (OVP, UVP, OCP).

5.3 Karatteristiċi ta' Protezzjoni

The TOB1S-63 provides the following adjustable protection features:

• Fuq Voltage Protezzjoni (OVP): Adjustable range 250-300V. The breaker will trip if the voltage exceeds this set limit.
• Taħt VoltagProtezzjoni e (UVP): Adjustable range 150-200V. The breaker will trip if the voltage drops below this set limit.
• Over Current Protection (OCP): Adjustable range 1-63A. The breaker will trip if the current exceeds this set limit.
• Protezzjoni ta' ċirkwit qasir: Non-adjustable, inherent protection against short circuits.

Adjust these settings via the Smartlife app interface for the device. After a trip event, investigate the cause before manually resetting the breaker.

6. Manutenzjoni

The TOMZN TOB1S-63 circuit breaker requires minimal maintenance.

• Spezzjona l-konnessjonijiet tal-wajers perjodikament biex tiżgura li jibqgħu ssikkati u ħielsa mill-korrużjoni.
• Żomm l-apparat nadif u ħieles mit-trab u l-fdalijiet. Uża drapp niexef u artab għat-tindif.
• Tużax prodotti tat-tindif likwidi jew solventi.
• Żgura ventilazzjoni xierqa madwar l-apparat biex tevita sħana żejda.
