(b) Cut the conductors to the length required to
attach them to appropriate terminals of TB2.
(c) Remove approximately 0.5 inches of insulation
from each conductor and install a terminal lug
intended for a #6 screw.
(d) Connect wires to TB2 as identified by the silk
screen markings adjacent to the terminal board
(positive to TB2-2, negative to TB2-1).
NOTE
Wind wires in step (d) through two turns of LXP38
toroid located in ancillary kit.
(e) Connect the other end of the wires to the
batteries or battery bank to be charged, ensuring
the wire connected to TB2-2 goes to the positive
terminal of the battery and the wire connected to
TB2-1 goes to the negative terminal.
NOTE
It is recommended that an on/off switch and a five
ampere fuse be placed in one of the wires going to the
batteries being charged.
3.8.5
POSITIONING OF BATTERY TEM-
PERATURE SENSOR:
Locate battery temperature
sensor U1 where it will sense the ambient temperature
of the air surrounding the batteries being charged,
observing the following:
(a) Verify the leads of temperature sensor U1 are
connected to terminal board TB2 as identified
by the silk screen markings adjacent to the
terminal board (white to TB2-3 and red to
TB2-4).
(b) Verify the leads of temperature sensor are
routed though the left-hand cable entry hole and
pass through the cable clamp securing the
wiring to the batteries being charged.
(c) Ensure the temperature sensor is located where
it will not be exposed to corrosive acids or
gasses.
3.8.6
POST-INSTALLATION INSPECTION:
Visually inspect the battery charger's interior after
installation and prior to applying power as follows:
(a) Check for obvious damage and missing parts.
(b) Verify attaching hardware is firmly tightened.
(c) Check electrical wiring for broken or frayed
insulation, loose or improper connections and
broken, shorted or pinched conductors.
(d) Verify connector P1 is mated with connector
A1J1 on printed wiring board A1, ensuring pins
are fully engaged.
(e) Check for and remove any unwanted foreign
objects from the interior of the cabinets, paying
particular attention for floating conductive
materials such as strands of wire, metal
slivers/filings and loose hardware.
INITIAL TURN-ON PROCEDURES
3.9
Special precautions must be taken, during
the initial turn-on of the battery charger, to safeguard
against failures incurred during transit and
installation. Prepare the battery charger for initial
turn-on after installation as follows:
(a) Verify the requirements of paragraph 3.8 have
been completed.
(b) Remove any loads that may be connected to the
batteries.
(c) Perform a complete calibration procedure as
detailed in paragraph 5.1.
NOTE
If fully charged batteries are connected to the battery
charger during initial turn-on, it will be necessary to
partially discharge them to complete the calibration
procedures.
If discharged batteries are connected to the battery
charger during initial turn-on, the time required to
complete the calibration procedure will be determined
by degree of discharge and the capacity of the
batteries.
