The control unit with microprocessor KER_EU can be used with motors having a power not exceeding
750W.
a) The wire connections and the operating logic should be in compliance with regulations in
force.
b) The cables featuring different voltage should be physically separated, or adequately insulated
by an additional insulation of at least 1 mm.
c) The cables should be further fastened in proximity to the terminals.
d) Check all connections before powering the unit.
e) Check that setting of the Dip-Switches are the required ones.
f) Normally Closed inputs which are not in use should be short-circuited.
