i
PWM operation: electrothermal actuators only have the positions Open and Closed. In
PWM operation, switch-on and switch-off during the drive's cycle time achieves an almost
constant behaviour.
4 Information for qualified electricians
4.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.
Connecting and mounting the device
DANGER!
When connecting the bus/extensions and mains' voltage wires in a shared
appliance box, the KNX bus cable may come into contact with the mains
voltage.
The endangers the safety of the entire KNX installation. People at remote
devices may also receive an electric shock.
Do not place bus/extensions and mains voltage terminals in a shared
connection compartment. Use an appliance box with a fixed partition wall
(Figure 5) or separate boxes.
