2 Installation Instructions
2.1 Input voltage
All inputs are provided with Opto couplers. To activate the inputs you can either use the internal switching
voltage or use an external supply. When using an external supply you must first change the internal jumper
setting of the control board. To do so carefully open the controller housing and set the jumper J2 in accordance
with the drawing and table below.
Attention!
The control board consists of electrostatic sensitive components. If working on the control boards
please use electrostatic save measurements to prevent any damage to the components. Do not touch the board
or any of the components!
