  The forthcoming SOXS (Son Of X-Shooter) will be a new spectroscopic facility
for the ESO New Technology Telescope in La Silla, focused on transient events
and able to cover both the UV-VIS and NIR bands. The instrument passed the
Final Design Review in 2018 and is currently in manufacturing and integration
phase. This paper is focused on the assembly and testing of the instrument
control electronics, which will manage all the motorized functions, alarms,
sensors, and electric interlocks. The electronics is hosted in two main control
cabinets, divided in several subracks that are assembled to ensure easy
accessibility and transportability, to simplify test, integration and
maintenance. Both racks are equipped with independent power supply distribution
and have their own integrated cooling systems. This paper shows the assembly
strategy, reports on the development status and describes the tests performed
to verify the system before the integration into the whole instrument.
