9.1 INSTALLATION
The installation orientation of Thyro-P is vertical, so that ventilation of the thyristors fastened to
heat sinks is ensured. In case of cabinet mounting, additionally sufficient ventilation of the cabi-
net must be ensured. The distance between Power Controller and the bottom should be at least
100mm; the distance to the ceiling 150mm. The devices may be installed next to each other with-
out lateral distance. Heating up of the device by heat sources must be avoided. The dissipation of
the Power Controller is stated in the table chapter 10 TYPE OVERVIEW.
Grounding must be performed according to local regulations of the utility company (grounding
screw for protective conductor connection).
9.2 PROTECTION AGAINST CONTACT IP20

To ensure protection during operation, the correct mounting is necessary of the added IP20 protec-
tion devices at each electric connection.
In the following description mounting of the protection devices is shown, this handling also applies
to 2- or 3- phase units of Thyro-P.
For devices of 16A/37A/75A/110A applies:
• The blind cover for non-used connections has to be pressed into the device cover until it snaps
into place.
• For devices of 110A, the covers have to be adjusted by the customer in accordance to the nee-
ded gaps while IP20 protection code has to be considered. Therefore gaps have to be chosen as
small as possible, so that needed IP20 protection code is ensured.
The cover has to be pressed into the device cover until it snaps into place.
For devices of 80A/130A/170A/200A/280A applies:
• The covers have to be adjusted by the customer in accordance to the needed gaps while IP20
protection code has to be considered. Therefore gaps have to be chosen as small as possible, so
that needed IP20 protection code is ensured.
• Afterwards the blind cover for non-used connections has to be pressed into the device cover
until it snaps into place.
For devices of 495A/650A applies:
Before connecting the device, the coverage has to be removed.
