Schneider Electric Acti 9 IH Mechanical Time Switch User Manual

1. Product Overview

The Schneider Electric Acti 9 IH mechanical time switch (Model CCT15365) is designed to automatically control electrical loads by switching them On and Off according to a user-defined daily program. This device features a 24-hour switching cycle with a minimum interval of 15 minutes between operations, allowing for up to 48 On and 48 Off switching points per day. It includes a 200-hour battery reserve to maintain program settings during mains power outages and offers a manual override function for temporary control. With a width of 54mm (equivalent to 6 modules of 9mm), it is suitable for standard electrical installations.

Key Features:

• Mechanical time switch for reliable operation.
• 24-hour daily switching cycle.
• Minimum switching time of 15 minutes.
• Up to 48 ON/OFF switching operations per day.
• 200-hour battery reserve for power outage protection.
• Manual override capability.
• Single channel output.

3. Setup and Installation

3.1 Safety Precautions

Before proceeding with installation, ensure that the main power supply is disconnected to prevent electric shock. Installation should only be performed by a qualified electrician in accordance with local electrical codes and regulations.

• Always disconnect power before installation or maintenance.
• Verify voltage and current ratings match your application.
• Do not expose the device to moisture or extreme temperatures.
• Ensure proper grounding if required by local codes.

3.2 Mounting

The Acti 9 IH time switch is designed for DIN rail mounting. Locate a suitable position within your electrical panel or enclosure.

1. Align the time switch with the DIN rail.
2. Press firmly until the device clicks securely into place on the rail.

3.3 Wiring

Refer to the wiring diagram on the device and the following instructions. Use appropriate wire gauges for the rated current (16 Amps).

• Connect the Live (L) input to the terminal marked 'L'.
• Connect the Neutral (N) input to the terminal marked 'N'.
• For the output, connect the switched Live to terminal '1' (Normally Open contact).
• Connect the load to terminal '2' or '3' as per your circuit design. Terminal '2' is typically the common, and '3' is the normally closed contact if applicable, but for this 1-channel switch, '1' is the switched output.
• Ensure all connections are tight and secure to prevent loose contacts and overheating.

3.4 Initial Power-Up

Once wiring is complete, restore power to the circuit. The time switch will begin operating. The internal battery reserve will charge automatically.

4. Operating Instructions

4.1 Setting the Current Time

The time switch features a 24-hour dial. To set the current time:

1. Rotate the outer dial clockwise until the current time aligns with the time indicator arrow (usually a small triangle or line on the fixed part of the switch).
2. Ensure accuracy for precise scheduling.

4.2 Programming the Timer

The dial has segments (pins) around its circumference, each representing 15 minutes. To program the ON/OFF times:

• To set an ON period: Push the pins outwards for the desired duration. When the dial rotates to these pushed-out segments, the switch will turn ON.
• To set an OFF period: Leave the pins in their inward position for the desired duration. When the dial rotates to these inward segments, the switch will turn OFF.
• Each pin represents 15 minutes. For example, to set a 1-hour ON period, push out 4 consecutive pins.
• You can set up to 48 ON and 48 OFF switching points within the 24-hour cycle.

4.3 Manual Override

The time switch includes a manual override switch, typically a small lever or button, allowing you to temporarily change the output state regardless of the programmed schedule.

• Locate the manual override switch (often labeled with an 'I' for ON and 'O' for OFF, or a hand symbol).
• Move the switch to the desired position (ON or OFF).
• The manual override will remain active until the next programmed switching point, at which time the timer will resume its automatic operation.

4.4 Battery Reserve

The integrated battery reserve provides up to 200 hours of power to maintain the time and program settings during mains power failures. The battery charges automatically when the device is connected to the mains supply.

5. Maintenance

The Schneider Electric Acti 9 IH mechanical time switch requires minimal maintenance.

5.1 Cleaning

• Ensure power is disconnected before cleaning.
• Wipe the exterior of the device with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the unit.

5.2 Battery

The internal battery reserve is designed for long-term operation and is not user-replaceable. If the time switch consistently loses time or program settings during power outages, it may indicate a depleted internal battery, and the unit may need professional inspection or replacement.
