4. Отсекти коопсуз жабыңыз.

2. DIN темир жол орнотуу

The timer is designed for standard 35mm DIN rail mounting. Simply clip the timer onto the DIN rail in your electrical panel.

3. Электр зымдары боюнча нускамалар

Маанилүү: Ensure power is disconnected before wiring. Refer to the diagrams below for correct wiring. The TM919A-3 model operates on 24V DC.

Image: Simple wiring diagram for connecting the timer directly to a load (e.g., a light bulb). Terminals 1 and 2 are for 24V DC input, and terminals 3, 4, 5 are for the switch output.

Image: Advanced wiring diagram showing the timer connected to an external contactor (ABB AX-09-30-10) for controlling higher power loads. The timer's output controls the contactor coil, which then switches the main load.

• Connect the 24V DC power supply to terminals 1 (+) and 2 (-).
• Terminals 3, 4, and 5 are the switch output. Terminal 4 is the common (COM), Terminal 3 is normally closed (NC), and Terminal 5 is normally open (NO).
• Connect your load (e.g., light, pump) to the appropriate output terminals based on whether you need it to be ON or OFF when the timer is active. For most applications, connect the load between terminal 5 (NO) and the power supply.
• For high-power loads, use an external contactor as shown in the advanced wiring diagram.
