CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment.

To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:

all connectivity work must be carried out with the power turned OFF;
use appropriate tools and personal protection against electric shock;
do not use damaged cables, wires and connectors;
avoid folding the cables and wires;
do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;
do not use the power socket with poor contacts to connect;
do not exceed the load limit parameters specified in the manual;
the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.

When the power is on, NEVER:

connect/disconnect the connectors;
open modules and sensors.

Connectivity recommendations

In order to protect the actuator and loads connected to it, installing a circuit breaker is recommended.
The nominal value of the circuit breaker should be calculated based on the maximum total load of connected
devices and at the same time should not significantly exceed the maximum permissible characteristics of the actuator.
Depending on the requirements, you can use one circuit breaker for one actuator (it is recommended)
or one circuit breaker per each group of connected loads, or, if necessary, a separate circuit breaker can be installed
for each load.

Connection of actuators

Caution: Before applying power to the module, you must properly configure the outputs in the application. The contacts configured incorrectly can lead to simultaneous power supply to both channels, resulting in the module failure and/or failure of the equipment connected to it, and even a fire.
If free (unused) channels remain in a given group after a curtain/jalousie/shutter actuator with low-voltage control or gate actuator has been connected to it, these channels need to be left unused. (Do not connect other devices to them!)
