Standards and reliability

Parameter	Details
Safety model	KAA-8R-10S
Safety standards	BS EN/EN 50491-3; BS EN/EN 60669-1, -2-1 and -2-5; EAC TP TC 004. The catalog identifies a Notified Body test report for the marked tests.
EMC emissions and immunity	BS EN/EN 50491-5-1, -5-2 and -5-3; BS EN/EN 50090-2-2; BS EN/EN 60669-2-1 and -2-5; BS EN/EN 63044-5-1, -5-2 and -5-3; EAC TP TC 020.
Withstand voltage	Between switching and SELV control circuits: 3.5 kVAC.
MTBF reference	597,800 hours minimum per Telcordia SR-332; 447,900 hours minimum per MIL-HDBK-217F at 25°C. Calculated reliability references, not guaranteed service life.
Specification conditions	Unless otherwise stated, parameters are measured at 230 VAC input, rated load and 25°C ambient temperature.
Manufacturer warranty reference	The catalog states a 3-year manufacturer warranty, subject to its applicable terms.

Manufacturer installation instructions

Parameter	Details
Terminal torque discrepancy	The current catalogue states 0.8 Nm, while the instruction manual recommends 5 kgf-cm (4.4 lb-in) at the screw terminals. These values differ. Confirm the instructions for the supplied hardware revision with MEAN WELL before tightening.
KNX terminal and cable layout	Use 0.6-0.8 mm solid-wire diameter at the KNX bus terminal and strip 5 mm. The manual lists 350 m maximum from the bus supply to the furthest device, 700 m between devices and 1000 m total bus-line segments; the stated maximum 256 devices remains subject to actual system power and topology.
Secure commissioning	For KNX Data Secure, use ETS5 version 5.5.0 or later, the device-specific FDSK from its label and the required project security configuration. The manual also allows unsecured operation when deliberately configured; secure capability alone does not mean the installed system is operating securely.
Relay-terminal preparation	The manual specifies 0.5-4.0 mm2 solid or 0.5-2.5 mm2 stranded conductors (12-26 AWG) for the relay terminals, stripped 8 mm, with a 4 mm slotted screwdriver. Confirm the applicable terminal torque separately.
Shutter and switch configuration	Configure the appropriate paired channels for shutter or blind motors. Follow the motor wiring instructions and its load limits; the actuator can also be configured for switching outputs or mixed use, rather than treating every output as an interchangeable motor direction.
