Power to the machine must be switched off before carrying out cabling. Connections are to be made in compliance with the wiring scheme of the controlled equipment. After installation has been completed, the installer is required to check that all commands are working properly. Avoid prolonged contact with oils and acids when using the equipment, as these may damage the products. 1) Using the locknuts (Ref. 27), attach the central pipe (Ref. 12) to a minimum 3 mm thick plate with a central hole of Ø 48.5÷52.5 mm (using the reducing cable clip on the nuts). As an alternative the central pipe (Ref. 12) can be attached to a plate with a threaded hole of Ø 48 mm, 1.5 mm pitch using the locknuts as jam nuts (Ref. 27).
