Installing the control box
If the contact 15/54 (auxiliary) of the starter key can withstand a continuous load of
10A, make the connections of Fig. 10 section A. Otherwise, insert a relay as shown in
Fig. 10 section B.
Minimum cable cross-section: 2,5 mm².
CAUTION: so as not to run the risk of short-circuiting, do not connect the supply
cable connector until installation has been completed.
