C-Control Pro Mega Series Installation In this chapter the installation of hardware and software is described. Applicationboard Important Note on Inserting/ Retrieving a Mega Module For the connection between Module and Application Board high quality connectors have been used in order to ensure intimate contacts. Mounting and dismounting of a Module should only take place during power-down condition (switched off voltage) since otherwise damages may occur to Application Board and/ or Module resp.
