2000 50A Ferroresonant Rectifier J85502B-1

5 - 2 Installation

Issue 6 May 1999

Bay Mounting

J85502B-1 rectifiers that are shipped as part of a battery plant are
installed in the battery plant racks before shipment. Rectifiers
ordered as individual units are shipped in individual containers.

The rectifiers mount in Lucent Technologies 26-inch wide bays,
with 24-5/16 inch mounting centers. The bays have drilled holes
on 1-inch centers, in the vertical plane, to accommodate #12-24
threads per inch self-tapping screws. Any restriction on the
location in the bays is described in the documentation for the
specific power plant.

Two 3/8-16 eyebolts are provided for lifting the rectifier into
position in the plant bay. They should be removed before the
rectifier is mounted permanently in the bay. A supplementary
bay that contains ONLY rectifiers should be located so that the
backs of the rectifiers are at least three inches from any wall.

Heat Dissipation

Heat dissipated to the environment is another factor in selecting
a location for the J85502B-1. The maximum heat exhausted by
each rectifier is approximately 845 BTU/hr (24-volt rectifier) or
1025 BTU/hr (48-volt rectifier). The rectifiers use free
convective cooling, where air enters the cabinet through
perforations in the bottom of the rectifier and escapes through
perforations in the top cover. A minimum of 10 inches in front
of the rectifier must be free of obstruction to allow the door to
open horizontally and provide for adequate ventilation.

AC Input Power

The customer is responsible for providing ac power to the
rectifier. Table 5-A provides requirements for the ac power
installation. Separate branch circuits must be provided to each
rectifier to assure reliability of the system. The wiring method
should meet national and local codes. If the codes governing the
installation allow it, Armored Cable (AC), also known at BX,
makes routing the ac wiring within the bay easier.

Figure 5-1 shows the ac input conduit hole. Figure 5-2 shows
termination points for the ac input wires. The “green wire” is the
AC equipment ground (AC EG), also known as frame ground
(FR GRD). Its termination point is on the left wall of the
rectifier near the ac input conduit hole.

Caution

Do not block rectifier ventilation openings or damage may
result due to overheating.
