INITIAL SET-UP & DESCRIPTION
Charger
The basic charging circuit is the silicon diode, rectifi-
er-type with ferroresonant transformer (s). This fer-
roresonant transformer design regulates charging
current by allowing the battery to determine its own
charge cycle rate in accordance with its state of dis-
charge. It provides a constantly-tapering charge
that eliminates the possibility of overcharging, even
with line voltage variations of ± 10%. Single-phase
input chargers have one transformer, three-phase
input chargers have two. The charger is internally
protected from overload and short circuits.
When charging lead acid batteries, with the same
number of cells and ampere-hour capacity as shown
on charger nameplate, the charging time will be
approximately 8 hours. Batteries of smaller or larg-
er ampere-hour capacities can also be charged, but
will require shorter or longer charging, respectively.
WARNING: Do not connect a
battery to this charger if any LED
is lit. Do not disconnect a battery
from this charger while a charge
is in progress. Otherwise, arcing
and burning of connector parts or
a battery explosion may result.
Batteries produce explosive gases.
Keep sparks, flame, and cigarettes
away. Ventilate when charging in
an enclosed area. Always shield
eyes when working near batteries.
Set-Up
See Location Diagram of Selector Switches includ-
ed in this manual.
For proper operation, the Control must be set to
match the charger in which it is installed.
