MODEL 25680

PLEASE SAVE THESE IMPORTANT SAFETY AND OPERATING INSTRUCTIONS

For correct operation of the equipment, it is important to read and be familiar

with this entire manual before installing and operating the discharger.

DO NOT DISCARD THIS MANUAL AFTER READING.

LOOK FOR THIS SYMBOL TO POINT OUT SAFETY PRECAUTIONS.  IT MEANS:

BECOME ALERT—YOUR SAFETY IS INVOLVED.  

IF YOU DO NOT FOLLOW THESE

SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.

A discharge unit is used to measure the remaining
or proportional useful energy for which a battery set
is capable.  Since slightly different methods are used
when determining a battery's useful energy, this
discharge unit has the capability of being
programmed to use a variety of discharge times and
shut-off voltages.  Other features which have been
designed in are:

Operates from battery voltage only (no AC supply)

Used on 72 volt battery systems only

Electronically controlled (uses microcontroller)

Programmable voltage or time shut-off

LED digital display for easy reading

Built-in thermal protection

8 foot DC cord with cord wrap built into handle

Durable eighteen gauge (18 Ga.) steel case with
powder coat paint

Large 500 amp alligator clamps for battery
connections

Three minute test cycle feature for measuring cell
voltages

Discharge data can be viewed or saved with a
terminal or computer

IMPORTANT SAFETY INSTRUCTIONS

1.

This manual contains important safety and
operating instructions for discharge unit Model
25680.

2.

Before using discharge unit, read all instructions
and cautionary markings on electric vehicle,
battery, battery charger, and all accessories

3.

Position the discharger on a foundation of stone,
brick, concrete or grounded metal.

4.

TO REDUCE THE RISK OF FIRE, DO NOT
USE THE DISCHARGER NEAR FLAMMABLE
MATERIALS OR VAPORS.

5.

Do not expose discharge unit to rain or snow.

6.

Use of an attachment not recommended or sold
by the discharge unit manufacturer may result in
a risk of fire, an electric shock, or injury to
