CAUTION
Bi-stable relays are used in the device, which may result in incorrect load control due to an undefined relay state on delivery!

There is a risk that the connected drive motors are destroyed.
During start-up, you must make sure that all relay contacts are open before switching on the load by applying the KNX bus voltage. Observe the start-up sequence:

  1. Switch on the KNX bus voltage.
  1. Wait approx. 10 s.
  1. Connect the load circuit.
CAUTION
National safety regulations

Failure to comply with national safety regulations may result in personal injury and property damage.

  1. Observe national provisions and comply with the appropriate safety regulations.
WARNING
Risk of death due to electric voltage and electric current!

Electrical expertise is required for the installation. Incorrect installation can deactivate electrical safety features without this being apparent to a lay person.

  1. The device should only be installed and put into operation by a certified electrician.
  1. When connecting the device, ensure that the device can be enabled.
  1. Do not open the housing of the device.
  1. Secure the phases with a B16 line protection switch.
  1. When planning and setting up electrical systems, observe the relevant guidelines, regulations and standards of the respective country.
  1. Do not connect DC or AC voltage to the inputs of the potential-free contacts (leads to damage/destruction of the device and voltage carry-over to the bus).
  1. Ensure safe separation of dangerous currents when connecting the potential-free contacts.
  1. Install the device in a location that is inaccessible to lay persons (e.g. flush-mounted box, sill duct, control cabinet).
  • Incorrect installation can deactivate electrical safety features without this being apparent to a lay person.
Passing on the device

If you pass on the device, ensure you also pass on the documentation for the device, such as, the operating instructions.
