8. Special remarks
Thyro-A requires a vertical fitting position. With cabinet mounting sufficient ventila-
tion of the cabinet must be ensured. The distance between the Power Controller and
the cabinet ceiling or other mountings should be at least 150mm. The distance be-
low the Power Controller should be at least 100mm. Heating up of the device by
heat sources must be avoided. The dissipation of the Power Controller is stated in
the Type overview table.
Grounding must be carried out according to local regulations! (a groun-
ding screw is provided for protective conductor connection on fastening
adapter). The grounding also serves EMV devices (Y capacitor 4.7 nF).
For single-phase devices with type currents 8, 16 or 30A an adapter can be delive-
red for the 35mm top-hat rail assembly.
The device must be connected to the mains and the associated load according to the
corresponding connecting plans.
On delivery the device is parameterized and adjusted to the respective power sec-
tion. The operating mode TAKT (S1-1, S1-2) for transformer load (R201) is set. If a
different operating mode is desired, then it must be set by the user. The following
table shows the default settings of the DIP switch.
