SECTION 3
INSTALLATION AND PREPARATION FOR USE
GENERAL
3.1
This section contains the information
required to prepare the equipment site to receive the
battery charger and the information required to
unpack, install and prepare the battery charger for use.
TEST EQUIPMENT
3.2
The test equipment required for initial
installation is listed in table 1-2.
SITE REQUIREMENTS
3.3 The battery charger is intended to be
mounted on the interior wall of a building. It should
have a minimum clearance of 12 inches (30 cm) at the
top, bottom and sides. There should be adequate
room at the front to permit the cabinet door to open
and permit a maintainer to test/trouble shoot the
battery charger.
3.3.1 ELECTRICAL POWER: /01 variations
require a 115 volt, line-to-neutral, 50/60 Hz ac power
source and /02 variations require a 230 volt, line-to-
neutral, 50/60 Hz ac power source. Either source
should be rated at a minimum of 500 Volt amperes.
3.3.2 ELECTRICAL POWER CABLE: The
ac power source cable should be a three wire (two
conductors plus ground) cable. It enters the battery
charger through a cable entry hole in the bottom of its
cabinet. Individual wires are connected to TB1-4
(line), TB1-5 (neutral) and safety ground stud.
3.3.3 BATTERY CABLE: The wiring from
the battery charger to the batteries to be charged
should be a two-conductor cable. The conductors
should be a minimum of 16 AWG (rated for seven
ampere maximum load). The battery cable enters the
battery charger through a cable entry hole in the
bottom of its cabinet. Individual wires are connected
to TB2-2 (+) and TB2-1 (-).
UNPACKING
3.4
The battery charger is packed, fully
assembled, in a wooden crate that is 20 inches (51 cm)
wide, 18 inches (46 cm) deep and 11 inches, (28 cm)
high. Shipping weight is approximately 55 pounds
(25 kg). A packing list provides a detailed listing of
crate contents.
ANCILLARY PARTS
3.5
An ancillary parts kit is provided with each
battery charger. These parts include the ferrite toroids
(LXP38) as well as hardware required for installation.
An itemized listing of the ancillary parts kit is
included in its packing list.
INFORMATION TO BE DETERMINED PRIOR
TO FINAL INSTALLATION
3.6
The following information must be
obtained by the end user prior to applying ac power
and final adjustment of battery charging current and
full charge shutoff voltage.
3.6.1 AC POWER SOURCE: The RMS
voltage of the ac power source (115 V ac or 230 V ac)
to be used must be determined.
3.6.2 TYPE OF BATTERY: The type of bat-
tery to be charged must be determined.
3.6.3 BATTERY VOLTAGE (NO LOAD):
The full charge, no load battery voltage at 25
°
C
(77
°
F) must be determined from the battery manufac-
turer's specification sheets.
3.6.4 CHARGING CURRENT: Determine the
constant charge current to be applied to the batteries,
based on the battery manufacturer's recommendations.
3.6.5 SPECIFIC GRAVITY: If batteries to be
charged contain provision to check their specific
gravity, determine what their specific gravity should
be when they are fully charged, from the battery
manufacturer's specification sheets.
