Several wiring methods of the timer switch
There are two types of wiring according to the power of the timer switch control appliances.
The first one.
1, the power of the appliance is less than or equal to 660W, you can directly wiring, zero and fire wire wiring order can not be connected to the wrong.
2, the timing switch is connected to the back of the air switch, the left side of the fire wire, the right side of the zero wire (2p), the timing switch into the line and the air switch connection.
3, the timing switch and electrical appliances connected, pay attention to the timing switch appears "zero", "fire" position, do not connect the reverse.
The second.
1, the power of the appliance is greater than or equal to 660W, you can not use the timing switch to directly control the appliance (beyond the power of direct control, timing switch is easy to burn out), you need to use with AC wiring, that is, the timing switch control AC contactor, AC contactor control high-power appliances.
2, timing switch connected to the back of the air switch, the left side of the fire line, the right side of the zero line (2p), the timing switch into the line and air switch connection.
3, connect the AC contactor and the air switch, the fire-zero wire of the air switch is connected to the L1 and L2 of the AC contactor. Connect the AC contactor and timing switch, the fire-zero wire of the timing switch is connected to A1 and A2 of the AC contactor. Connect the AC contactor and the electrical appliance, the fire-zero wire of the appliance is connected to T1 and T2 of the AC contactor.
