B ATTERY C HARGER O PERATION
The ETS-Lindgren voltage-selectable battery charger is solely intended for
charging the sealed lead-acid batteries found in ETS-Lindgren products. The
battery charger is a means of providing the necessary charge voltage and current
from either a 115 VAC 50/60 Hz or 230 VAC 50/60 Hz source.
It is necessary to select the proper input voltage prior to connecting
the battery charger to the power mains. The voltage select switch is
located adjacent to the power input receptacle.
To maintain safety requirements, use the CSA-certified power cord provided. If it
is necessary to provide other means of attaching the battery charger to the power
mains, it is required that a Type HD 21 (PVC cord) or Type HD 22 (rubber cord)
with a nominal cross-section of 0.75 mm 2 be used.
The battery charger provides both fast and trickle charge operation. Switching
from one charge mode to the other is provided automatically by the charger. The
front panel indicator marked FAST CHARGE illuminates when the battery
charger is in the fast charge mode. When the POWER ON light is illuminated and
the FAST CHARGE light is extinguished, the battery charger is in the trickle
charge mode.
Always remove mains power before opening
the housing.
The battery charger is protected against overcurrent by a 200 mA 250 VAC
time-delay fuse. If it becomes necessary to replace the fuse, use a fuse of the
same type and rating to maintain safe operation. The fuse is accessible by
removing the two Phillips head screws on the underside of the unit. The output of
the battery charger is protected against overcurrent conditions by use of
fold-back circuitry.
