The TM612 is designed for 36mm DIN rail mounting. Ensure that installation is performed by a qualified electrician in accordance with local electrical codes and regulations.

5.1 Mounting

1. Locate a suitable 36mm DIN rail within your electrical enclosure.
2. Align the timer switch with the DIN rail and press firmly until it clicks into place.
3. Ensure the device is securely fastened to prevent accidental dislodgement.

5.2 Wiring

Refer to the wiring diagram typically found on the device itself or in the included quick-start guide. The TM612 features two independent volt-free relay outputs. Connect the power supply (220V AC) to the designated input terminals (L and N). Connect your loads to the respective output terminals (C1, 1, 2 for Channel 1 and C2, 3, 4 for Channel 2, or similar markings depending on the specific unit). Always ensure power is disconnected before wiring.

5.3 Initial Power-Up and Battery Installation/Check

The device comes with a replaceable 3V CR2032 battery for backup. Upon initial power-up or after a prolonged power outage, the display may be blank or show incorrect time. The battery ensures that programmed settings are retained during power interruptions.

• If the display is blank, ensure the main power supply is connected and stable.
• The internal battery charges when the device is powered. Allow some time for the battery to charge if it's completely depleted.
• To replace the battery, carefully open the battery compartment (usually on the front or side) and insert a new CR2032 battery, observing polarity.

6. Operating Instructions
