4.2 Dyagram fil elektrik

The wiring configuration depends on the model (16A or 30A) and whether a contactor is used for higher loads. Always ensure power is disconnected before wiring.

4.2.1 TM928SAKL (16A Model) Direct Load Wiring

For loads up to 16A, the timer can directly control the device. Connect the Line (L) and Neutral (N) to terminals 1 and 2 respectively for power supply. The load is connected between terminal 3 (NO - Normally Open) and the Neutral (N) line. Terminal 4 (NC - Normally Closed) is not used in this configuration.

4.2.2 TM928SAKL (16A Model) with Contactor

For inductive loads or loads exceeding 16A, a contactor must be used. The timer controls the contactor coil, which in turn switches the main load circuit. Connect the timer's output (NO terminal 3) to one side of the contactor coil, and the other side of the coil to Neutral (N). The main power for the load passes through the contactor's power contacts.

4.2.3 TM928SBKL (30A Model) Direct Load Wiring

For loads up to 30A, the TM928SBKL model can directly control the device. Connect the Line (L) and Neutral (N) to terminals 1 and 2 respectively for power supply. The load is connected between terminal 3 (NO - Normally Open) and the Neutral (N) line. Terminal 4 (NC - Normally Closed) is not used in this configuration.

4.2.4 TM928SBKL (30A Model) with Contactor

For inductive loads or loads exceeding 30A, a contactor must be used. The timer controls the contactor coil, which in turn switches the main load circuit. Connect the timer's output (NO terminal 3) to one side of the contactor coil, and the other side of the coil to Neutral (N). The main power for the load passes through the contactor's power contacts.
