Battery Charger: Models 6502 and 6507
The Model 6502 and Model 6507 are powered by two 6-VDC, sealed lead-acid
batteries. The included battery charger is intended for charging only the sealed
lead-acid batteries in ETS-Lindgren products.
The Model 6502 is not designed to operate using the battery charger
as a power source.
When the batteries are completely discharged, charging time is approximately
eight hours. Batteries should provide power for approximately 16 hours before

 Voltage selection switch— The battery charger is voltage-selectable,
providing the necessary charge voltage and current from either a
115 or 230 VAC 50/60 Hz source. The voltage selection switch is
located next to the power input receptacle.
Select the proper input voltage before connecting the battery charger
to the power mains.
 Power On— Illuminates when the charger is plugged into an AC outlet.
 Battery charging port— Located on the front of the unit.
Always remove main power before opening the
battery charger case.
 Fuse— A 200 mA 250 VAC time-delay fuse protects against
overcurrent. When replacing the fuse, use a fuse of the same type and
rating to maintain safe operations; see the battery charger
specifications on page 17 for more information. The fuse is accessible
by removing the two Phillips head screws on the bottom of the unit.
