5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Fitting the device
Observe the temperature range. Ensure sufficient cooling.
o
Mount the device on DIN rail. Output terminals must be at the top.
Connecting the device
Note permitted loads.

Outputs not used for controlling fan levels can be used for simple switching. Please see
configuration data for the assignment of output terminals.
o
Connect bus cable with connecting terminal (figure 3).
o
Connect the mains power supply.
o
Connect fan-coil-units to the outputs of the actuator in accordance with configuration.
o
If multiple miniature circuit breakers supply dangerous voltages to the device or load,
couple the miniature circuit breakers or label them with a warning, to ensure release is
guaranteed.
i
A fan-coil output with up to six fan levels: see connection example (figure 3). Information
regarding assignment of the outputs in (table 2), (figure 4) and (figure 5).
i
Two fan-coil outputs with up to three fan levels each: see connection example (figure 6).
Information regarding assignment of the outputs in (table 3), (figure 7) and (figure 8).
i
Please refer to the documentation of these devices for more details on connecting fan-coil
devices.
