BTU/hr. The rectifiers use free convective cooling, where cooler
air enters the cabinet through perforations in the front bottom
plate and is exhausted through perforations in the top cover. A
minimum of 66.04cm (26 inches) in front and 30.48cm
(12 inches) above the rectifier must be free of obstructions to
allow the door to swing free and provide for adequate
ventilation. In a side-by-side alignment of rectifiers, the cabinet
door opens 90
o
and projects approximately 33 cm into the front
aisle causing no interference with adjacent rectifiers.
Warning:
Do not block rectifier ventilation openings or damage may result
due to overheating.
AC Input Power
The customer is responsible for providing ac power to the
rectifier. Table 5-A gives requirements for the ac power
installation. Separate branch circuits must be provided to each
rectifier to ensure the reliability of the system. A branch circuit
consists of all the phase leads to a rectifier plus the ac equipment
ground (AC EG). The wiring method should meet national and
local codes. A screw-type terminal is supplied on the rectifier.
Figure 5-4, top view of the rectifier, shows openings for the ac
input conduit and two required grounds. Figure 5-3 shows the ac
input wire termination points.
1. Input wire count includes one “green wire” ground.
Consult Table 5-A and choose #14 AWG green, comcode
407405497 or #10 AWG green, comcode 407405570. For
phase wiring, use KS24194 L3 (#14 AWG, comcode
407405489 gray; #10 AWG, comcode 407576636 gray; #6
AWG, comcode 407405646 gray) or 75° C commercial
wire.
