§ Fix each wire tightening each pin from the front side with a hexagonal
screwdriver (Allen number 2).
§ Push the insert back into the hood/housing.
§ Fix the assembly tightening the top locking screw and tightening the
cable gland nut on the back of the hood/housing.
b) MBS Unit with DC power supply source:
q Nominal voltage: 24 VDC (Range: from 21.6 to 31.2 VDC).
q Use the power cable connector provided with the MBS Unit to connect the
MBS Unit to the power supply source. Use a cable of 3 wires with weather
protection and the following features:
§ Cable diameter: 10 mm - 14 mm.
§ Cable section: 6 mm² (0.6/1KV) or AWG-10.
§ Maximum cable length1:
- One MBS Unit: 85 m.
- Two MBS Units: 42 m.

The greater the cable length, the greater the voltage drop in it. The specified length has been calculated to ensure
minimum operating voltage of the MBS Unit, assuming a minimum voltage of 24V at the output of the power system and a
typical resistivity of copper wire Ω ≤ 0.0172 mm
