Frequently Asked Questions - GW90708 Gewiss

How do I install the Gewiss GW90708?

Installation should be performed by a qualified electrician. Ensure the power is turned off before wiring. Follow the wiring diagram provided in the manual.

What is the maximum load for this device?

The maximum load is 10 A at 250 V AC. Do not exceed this rating to avoid overheating or damage.

Is the GW90708 compatible with LED lights?

Yes, but ensure the total LED load does not exceed the rated current. Some LEDs may require a minimum load; check the LED specifications.

Can I use this switch with a dimmer?

This model is a standard on/off switch and is not compatible with dimmers. Use a dedicated dimmer switch for dimmable lighting.

How do I clean the GW90708?

Clean with a dry, soft cloth. Do not use water, solvents, or abrasive cleaners as they may damage the surface.

What is the protection rating of this device?

The device has an IP20 rating, suitable for indoor use where it is protected against solids larger than 12 mm but not against water.

Is the GW90708 child-safe?

Standard switches do not have built-in child safety features. For additional safety, consider using child-proof covers or installing at a height out of reach.

Where can I download the manual?

The manual is available for free on notice-facile.com. Search for 'Gewiss GW90708' and download the PDF.

Can I replace an old switch with this model?

Yes, if the old switch has the same mounting box size (typically 80 x 80 mm) and wiring configuration. Consult a professional if unsure.

What is the warranty period?

Gewiss offers a 2-year warranty against manufacturing defects. Keep the purchase receipt for warranty claims.

This device is a product of the KNX-EIB System and complies with KNX directives.

Detailed technical knowledge obtained in KNX-EIB training courses is a prerequisite to proper understanding.

The functionality of this device depends on the software.

Detailed information on loadable software and attainable functionality as well as the software itself can be obtained from the manufacturer's product database.

Planning, installation and commissioning of the unit is effected by means of KNX-certified software.

An updated version of the product database and the technical descriptions are available in the Internet at www.gewiss.com.

WHAT YOU CAN DO WITH THE AREA/LINE COUPLER

The coupler connects two BUS KNX-EIB data lines and ensures the electrical separation of these lines from one another.

The definite functions of the device are defined by addressing and parameterization.

Line coupler LK:

Physical address X.0.0.

Connection of a main line (HL) with an area line (BL). Alternatively with or without filter function. The coupler belongs logically to the subordinate line.

Area coupler BK:

Physical address X.0.0.

Connection of a main line (HL) with an area line (BL). Alternatively with or without filter function. The coupler belongs logically to the subordinate line.

Amplifier V:

Physical address X.Y.Z.

Handing and repetition of telegrams on a line, no filter function.

Division of a line into max. 4 independent line segments ≥ max. 3 line amplifiers connected in parallel per line (FIG. C). Each line segment requires a separate power supply (SV) including a choke (DR).

Function of diagnosis LED ("DIAG") red

LED off: telegrams are filtered or blocked (both directions)

LED on: telegrams are retransmitted without being filtered (at least one direction)

LED flashing: error detected (as per error flags in device)

Function of operation LED ("RUN") green

LED off: device off, no voltage on main line

LED on: device on, voltage on both lines

LED flashing: no voltage on subordinate line

HOW TO INSTALL THE AREA/LINE COUPLER

1 The device is snap-fastened on the DIN rail until the latch is heard to engage, with the connecting terminals pointing downloads

2 The main line is connected with the left-hand terminal (terminal "HL"). This terminal supplies power to the device electronics so that it is possible to report a bus voltage failure of the subordinate via the main line.

3 The subordinate line is connected to the right-hand terminal (terminal "UL").

Removal info: Do not lever out the connecting terminal from below.

Risk of shorting the bus voltage which is not available during the short-circuit.

HOW TO SET UP THE AREA/LINE COUPLER

Danger:

The device must be mounted and commissioned by an authorised electrician. The relevant guide lines, regulations and standards of the respective country.

1 Download the physical address in the device via ETS.

2 Set the parameters of the coupler and download them via ETS.
