Himoinsa M1 - Inputs and Outputs

DIMENSIONS, WIRING AND MECHANICAL PARTS | PAGE 17
The equipment must be isolated or disconnected before connecting the voltage
input for the generator, as there is a risk of danger.
The USB connector complies with the standard 2.0. To power the control unit, it
is recommended that a cable be used with a cross-section of 1 mm

.
A cable with a cross-section of 2.5 mm

must be used for +BAT, ARR, PR and PC
connections. For the rest of the connections it is recommended that a cable be
used with a cross-section of 1 mm
