Infinity B (NE-B) G240 System -48V, +24V,
+24V/-48V or –48V/+24V
Use a #10 or 1/4" diameter double-hole lug on 5/8"
center (Not provided) to ground the chassis; Torque
connections to 35 in- lbs using 5/16" nut driver
The ac input panel is directly above the top row of
power modules. 1" and 1-1/2" conduit knockouts are
located on the left and right ends of the ac panel.
Each rectifier position is factory configured for
individual 208/220VAC inputs. Individual inputs
require 20A protectors and 10 AWG wires. Two
rectifier positions can be fed from one ac source by
installing the provided jumpers. When using one
input for two rectifiers a 40A protector and 8 AWG
wire is required. Recommend two 1-1/2" conduits
feeding up to 8 rectifiers per conduit; (16) 10 AWG
