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 tempe
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 ex
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
