3.15 End Cell Switch Inhibit: A positive battery control
signal fs available at TB3 terminal 13 to inhtti activation
of an automatically controlled end cell switch during nor-
mal rectifier operation. If a low current ahrm occurs in
the rectifier, this control signal is automatically removed
3.16 fj& A positfve battery alarm signal is present at
output voltage condition.
3.17 LCA: A poskfve battery alarm signal is present at
3.18 m Positlive battery to TB3 terminal 16 is nor-
mally supplied through a factory installed jumper wire
between terminals 16 and 20. Positive battery at termi-
nal 16 of TE3 is required for AC input power contmf. If
location or automatic control device. disconnect and
or control device.
3.18 Voftmeter lndicatffa O~tiin: Connect terminals
17 and 16 of TD3 with a jumper wire if front panel voft-
meter indfff of battery voftage is desired when rectii
fier fs turned off. lf voftmeter indication of zero volts is
desired with rectifier turned off, do not connect jumper
to teninals 17 and 18.
tiier is operating in ffoat mode, positive battery is avafl-
able at TB3 terminal 19. When the equalize mode is
selected, positfive battery is removed from TD3 terminal
19 and supplied at terminal 21.

longed AC input power failure. the associated battery
discharges to below 36 VDC, the rectifier will be unable
to restart. To permit restartiig the rectifiir in thff went,
a customer-furnished auxiliary 49 voft power supply may
be connected to terminals 1 (+) and 2 (-) of auxiliary
power supply tenfnal bfodc TM. TBI is located on
amperes.

by the manufacturer before sh@ment: however, the
installer should perform the following initial checks to
insure proper equipment operation after installatfon is
completed.

a) Initial Preoaration
Place the HVSD and POWER
switches on the front panel to the OFF
position. Place the FLOATIEQUAL-
Open the front access panels by loos-
ening the captive fasteners, then
locate battery disconnect link 52.
Remove this link from its receptacle.
Check to insure mat all fuses are
securely installed in their fuseholders.
Any tape and packing materials used
in the interior of the rectifier for ship-
ping purposes should be removed at
this time.
Connect all input. output, and control
Data sheet. Refer to Paragraph 3.06
for further wiring information.
b)
DANGER
Steps 1J through 4) must be pelf-d exactly
filter capacitor8 before installing
If reference leads are extended to the
battery, perfom the folfowfng steps:
Remove the local sensing
leads from their storage termi-
nals on circuft card A9.
Working with one lead at a
time, disconnect the extended
reference leads from terminals
1 and 2 of TB3 on circuit card
leads.
Connect the local sensing
leads to TBS. terminal 1 (+)
