SAVE  THESE  INSTRUCTIONS

.   This  manual contains important  safety  and  operating  instructions.    Before

using this equipment, read all instructions and cautionary markings on  (1) unit, (2) battery, and (3) product

using the battery.

2.

 

CAUTION:  To reduce risk of injury and/or damage to the batteries, use only the type of batteries specified on

the charger nameplate.

3.

 

Do not expose equipment to rain or snow.

4.

 

Do not operate equipment if it has received a sharp blow, been dropped, or otherwise damaged in any way;

take it to a qualified serviceman.

5.

 

Do not disassemble this unit; take it to a qualified serviceman when service or repair is required.  Incorrect re-

assembly may result in a risk of electric shock or fire.

6.

 

To reduce risk of electric shock, disconnect this unit from the AC supply, batteries and loads before attempting

any maintenance or cleaning.  Turning off controls will not reduce this risk.

7.

 

WARNING

 

 RISK OF EXPLOSIVE GASES

a.

 

Working  in  the  vicinity  of  a  battery  is  dangerous.    Some  batteries  generate  explosive  gases  during  normal  battery

operation.  For this reason, it is of utmost importance that each time before using this unit, you read this manual and

follow the instructions

b.

 

To  reduce  risk  of  battery  explosion,  follow  these  instructions  and  those  published  by  the  battery  manufacturer  and

manufacturer  of  any  equipment  you  intend  to  use  in  the  vicinity  of  the  battery.    Review  cautionary  marking  on  all

products.

8.

 

PERSONAL PRECAUTIONS:

a.

 

Someone should be within range of your voice or close enough to come to your aid when you work near a battery.

b.

 

Have plenty of fresh water and soap nearby in case the battery electrolyte contacts skin, clothing, or eyes.

c.

 

Wear complete eye protection and clothing protection.  Avoid touching eyes while working near a battery.

d.

 

If the battery electrolyte contacts skin or clothing, wash immediately with soap and water.  If the electrolyte enters the

eye,  immediately  flood  the  eye  with  running  cold  water  for  at  least  ten  (10)  minutes  and  get  medical  attention

immediately.

e.

 

Never smoke or allow a spark or flame in vicinity of a battery.

f.

 

Be extra cautious, DO NOT drop metal onto a battery.  It might spark or short-circuit the battery or cause an explosion.

g.

 

Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery.  A battery

can produce a short-circuit current high enough to weld these items causing severe burns.

h.

 

NEVER charge a frozen battery.

i.

 

Do not use battery charger for charging dry-cell batteries that are commonly used with home appliances.  These batteries

may burst and cause injury to person or damage to property.

9.

 

PREPARING TO CHARGE

a.

 

If it is necessary to remove the battery connections, always remove grounded terminal from the battery first.  Make sure

all loads are disconnected and unit is off, so as not to cause an arc.

b.

 

Be sure the area around the battery is well ventilated while the battery is being charged.

c.

 

When cleaning battery terminals, be careful to keep corrosion from coming in contact with eyes.

d.

 

Study all the battery manufacturer

s specific  precautions  such  as  removing  or  not  removing  cell  caps  while  charging,

recommended rates of charge, and maintenance procedures.

e.

 

Follow the battery manufacturer's recharging instructions.

10.

 

UNIT LOCATION

a.

 

Never  place  this  unit  directly  above  the  standard  flooded  battery.    Gases  from  the  battery  will  corrode  and  damage

equipment.  A sealed maintenance free or valve regulated lead acid (VRLA) may be placed below this equipment.

b.

 

Never allow the battery electrolyte to drip on this unit when reading the specific gravity or filling the battery.

c.

 

Do not operate this unit in a closed-in area or restrict ventilation in any way.

d.

 

Do not set any battery on top of this unit.

11.

 

DC CONNECTION PRECAUTIONS

Connect and disconnect DC output cables only after setting all of this unit's switches to off position and removing AC

input supply.  Do not pull on output cables when disconnecting charger from battery.
12.

 

GROUNDING INSTRUCTIONS

This  battery  charger  should  be  connected  to  a  grounded,  metal,  permanent  wiring  system;  or  an  equipment

grounding conductor should be run with circuit conductors and connected to equipment-grounding terminal or lead

on battery charger.  Connections to battery should comply with all local codes and ordinances.
