A Helios DC System 4000/48 rectifier cabinet equipped with six Helios Rectifier 200I/48 or 200E/

48 will dissipate a maximum of 8,010 watts or 27,350 Btu/hr.

The floor loading is based on a footprint of 600 mm x 600 mm (23.6 in. x 23.6 in.) plus a 30-inch 

aisle width (15 inches front and rear).
The point loading is based on distributing the cabinet weight over four shims, each with an 

assumed area of 25.8 cm
