ATTENTION
FOR INSTALLATIONS WHERE A SEALING IS REQUIRED TO AVOID LIQUID CONTACT, THE CUT FOR THE CONTROLLER MUST BE OF
70,5X29mm MAXIMUM. THE SIDE LOCKS MUST BE FIXED SO IT PRESSES THE RUBBER SEALING AVOIDING
INFILTRATION BETWEEN THE CUT AND THE CONTROLLER.
IMPORTANT
THE USE OF APPROPRIATE TOOLS IS ESSENTIAL TO AVOID DAMAGE IN THE CONNECTION AT INSTRUMENT TERMINALS:
SCREWDRIVER SLOT 3/32''(2.4mm) FOR ADJUSTMENTS IN THE SIGNAL TERMINALS;
