Important warning: the cables to be connected to the controller contacts should resist to the maximum
operating temperature which is determined by considering the expected maximum ambient temperature +
the controller overheating equal to 20°C. Moreover, it is necessary to protect the controller with a 1A,
250V protection fuse should be placed.
CONNECTIONS
Caution: with respect to safety rules follow the
below quoted instructions carefully:
• The cables to be connected to the controller
contacts should resist the maximum operating
temperature which is determined by considering
the maximum ambient temperature expected +
the controller auto-heating equal to 20 °C.
• Moreover, it is necessary to protect the
controller with a 1A, 250V fuse.
• Connect the terminals 12, 15 and 17 to the
same electric potential, as shown in the picture
