Product Usage Instructions

Ensure that the safety and usage instructions provided with the product are followed to guarantee its safety.
Make sure to share these instructions with the installer and end user.
Use the product only for its intended purpose. Any other form of use may be considered improper and dangerous.
In case of a voltage failure, the device will memorize the status of active functions. Upon power supply restoration, active power thresholds will be reassessed.
To view electrical network parameters, follow these steps:
- From the Instant Power page (10), press and hold the button or the button for at least 5 seconds until the first parameter (11) is displayed.
- The displayed parameters include:
1. Current [A]
2. Voltage [V]
3. Power Factor
4. Frequency [Hz]
To reset energy counters, follow these steps:
- From the Energy page (2, 3), press and hold the SET button for at least 5 seconds until the confirmation page (6, 7) is displayed.
- Press the SET button to reset the counter. Press the button or the button to cancel the reset operation.
Ensure that qualified personnel installs the device, following current regulations and KNX installation guidelines.
Avoid contact between unused BUS signal cables, electrical continuity conductors, and live elements or earthing conductors.
Disconnect the mains voltage before installing or working on the device.

INSTRUCTION

The safety of the device is only guaranteed if the safety and usage instructions are respected, so keep them handy. Make sure these instructions are received by the installer and end user.
This product must only be used for the purpose for which it was designed. Any other form of use should be considered improper and/or dangerous. If you have any doubts, contact the GEWISS SAT technical support service.
The product must not be modified. Any modification will annul the warranty and may make the product dangerous.
The manufacturer cannot be held liable for any damage if the product is improperly or incorrectly used or tampered with.
Contact point indicated for the purposes of fulfilling the applicable EU directives and regulations:

ATTENTION: the device must only be installed by qualified personnel, observing current regulations and the guidelines for KNX installations.
ATTENTION: the unused BUS signal cables, and the electrical continuity conductor, must never touch any live elements or the earthing conductor.
ATTENTION: disconnect the mains voltage before installing the device or carrying out any work on it.
If the crossed-out bin symbol appears on the equipment or packaging, this means the product must not be included with other general waste at the end of its working life. The user must take the worn product to a sorted waste centre, or return it to the retailer when purchasing a new one. Products ready for disposal and measuring less than 25cm can be consigned free of charge to dealers whose sales area covers at least 400m², without any purchase obligation. An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its subsequent recycling, helps avoid the potential negative effects on the environment and people’s health, and encourages the re-use and/or recycling of the construction materials. GEWISS actively takes part in operations that sustain the correct salvaging and re- use or recycling of electric and electronic equipment.

IN BRIEF

The KNX meter performs the function of measuring the energy power on the KNX BUS and is able to monitor up to twenty absorption limit threshold levels. It’s installed on a DIN rail inside an electric board or junction box. The device supports KNX Data Secure: this technology increases the security of a KNX installation both during start-up as well as during normal operation through the exchange of encrypted telegrams.
The device is fitted with (see Figure A): $GEWISS-GWA9801-Direct- Connection-Energy-Meter-FIG-1 $1$$

Power supply phase input
Power supply neutral input
Neutral output for measuring instantaneous power
- Backward push-button
- Forward push-button
- push-button The device has a segmented display for viewing:
the electric measurement/parameter visualized, the relative value and signaling icons
Active parameter setting mode
Active power threshold; icon on if the threshold is exceeded, off if not exceeded
Energy measurement unit kWh
Power measurement unit kW

FUNCTIONS

The device performs the following functions:
Measurement of electric sizes

During normal operation, the display can show (Figure C): $GEWISS-GWA9801 -Direct-Connection-Energy-Meter-FIG-1 $3$$

Instantaneous active power; “P-” is indicated if the power is produced
Active energy consumed; max. 5 figures (99999 kWh, 2 above and 3 below)
Active energy produced; max. 5 figures (99999 kWh, 2 above and 3 below)
Power threshold status: “OFF”; “ON” based on the status of its activation for the monitoring function
As per the previous point

The device shows the absorbed power page (1) 60 seconds after the last pressing of a button key. The device can transmit the sizes measured via KNX.

For information purposes only, information about the electric network parameters is available. To view these data (Figure D), go to the instantaneous power page (10) and press the or button UP DOWN key for at least five seconds until the first parameter (11) appears. The parameters available are:

11. Current [A]
12. Voltage [V]
13. Power factor
14. Frequency [Hz]

Energy counter reset
The energy counters (produced and consumed energy) can be reset (Figures E, F): from the energy page (2, 3), press the SET button key for at least 5 seconds until the confirmation page (6, 7) appears. Press SET to reset the counter; press UP DOWN or to annul the reset operation. Power thresholds
It is possible to set up to twenty absorption limit thresholds to be monitored; it is possible to send signals when these thresholds are exceeded or not and count how long the measured power is above the threshold or how many times it exceeded the limit. It is possible to activate or deactivate threshold monitoring by subsequently pressing the SET button key (8, 9, in Fig G). $GEWISS-GWA9801-Direct-Connection-Energy-Meter-FIG-1 $3$$

BEHAVIOUR UPON BUS VOLTAGE/POWER SUPPLY FAILURE AND RESET
If a voltage failure takes place, the device memorises the status of the various active functions; when the power supply is restored, any active power thresholds are reassessed again.

ASSEMBLY

For the electrical connections, refer to figures H and I. To connect the KNX bus terminal, refer to Figure B. $GEWISS-GWA9801-Direct-Connection-Energy- Meter-FIG-1 $2$$ To operate correctly, the meter must be installed immediately downstream from the main switch (which should be a switch disconnector according to Standard CEI 64-8 V3, but which in this case must be a miniature circuit breaker (MTC) to protect the meter); in this way, it can measure the real consumption of the home. The meter neutral output (3) must be connected to the input of the two residual current circuit breakers of the home.

PROGRAMMING

The device must be configured with the ETS software. The device supports the KNX Data Secure protocol and can be programmed to communicate securely on the bus. Detailed information about the configuration parameters and their values is given in the Technical Manual (www.gewiss.com).
