Installation

The time switch is designed for mounting onto a DIN rail in your consumer unit/distribution box
and may only be installed by a qualified electrician.
1. Install the time switch by hooking the time switch's hooks over the DIN rail. Then press
the time switch's bottom edge to lock it against the DIN rail.
2. Connect the phase (live) and neutral wires to the L and N connections. Protect the current
carrying lead (phase) with a max 16 A fuse.
3. Connecting channel 1: Connect the desired circuit to be controlled to the CH1 terminals.
4. Connecting channel 2: Connect the desired circuit to be controlled to the CH2 terminals.
5. Tighten the screws securely for proper contact. Make sure that the connected leads are
properly stripped free of cable insulation to ensure a clean contact area.
Things to consider:
Since all electronic equipment is sensitive to voltage peaks, you should try to isolate the time
switch by connecting it to a separate phase circuit than the one you will use for controlling your
electronic equipment.
