9.4 If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If
electrolyte enters eye, immediately flood the eye with running cold water for at least 10
minutes and get medical attention immediately.
9.5 NEVER smoke or allow a spark or flame in vicinity of battery or engine.
9.6 Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or
short circuit battery or other electrical part that may cause explosion. Using insulated tools
reduces this risk, but will not eliminate it.
9.7 Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a storage battery. A storage battery can produce a short circuit current high
enough to weld a ring or the like to metal, causing a severe burn.
9.8 When charging batteries, charge LEAD-ACID or LIQUID ELECTROLYTE
NICKEL-CADMIUM batteries only. Consult SENS before using with any other type of
battery - other batteries may burst and cause injuries to persons and damage to property.
9.9 NEVER charge a frozen battery.
9.10 Consult national and local ordinances to determine if additional battery fault protection is
necessary in your installation.
10. PREPARING BATTERY FOR CHARGE
10.1 Be sure area around battery is well ventilated while battery is being charged.
10.2 Ensure battery terminals are clean and properly tightened. Be careful to keep corrosion
from coming in contact with eyes.
10.3 Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. Do not overfill. For a battery without removable cell caps, such as valve
regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
10.4 Study all battery manufacturer specific precautions such as removing or not removing cell
caps while charging and recommended rate of charge.
11. CHARGER LOCATION
11.1 Locate the charger as far away from the battery as DC cables permit.
11.2 Never place charger directly above or below battery being charged; gases from battery will
corrode and damage charger.
11.3 Never allow battery acid to drip on charger when reading electrolyte specific gravity or
filling battery.
11.4 Do not operate charger in a closed-in area or restrict ventilation in any way.
11.5 Do not set anything on top of the charger.
IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS –This guide contains important safety and operating instructions
for EnerGenius®DC battery chargers.
2. Do not expose charger to rain or snow.
3. Use of an attachment not recommended or sold by the battery charger manufacturer may result in
a risk of fire, electric shock, or injury to persons.
4. This charger is intended for commercial and industrial use. ONLY TRAINED AND QUALIFIED
PERSONNEL MAY INSTALL AND SERVICE THIS UNIT.
5. Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in
any way; shut off power at the branch circuit protectors and have the unit serviced or replaced by
qualified personnel.
6. To reduce risk of electric shock, disconnect branch circuit feeding charger before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.
7. Use appropriate lockout / tagout procedures to ensure safety of all personnel installing and
servicing this equipment. The input and output breakers are equipped with provision to lock
breakers in the OFF position.
8. WARNING – RISK OF EXPLOSIVE GASES
8.1 WORKING IN VICINITY OF A LEAD-ACID OR NICKEL-CADMIUM BATTERY IS
DANGEROUS. STORAGE BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU READ THIS DOCUMENT AND FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
8.2 To reduce the risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity of
a battery. Review cautionary markings on these products
and on engine.
9. PERSONAL PRECAUTIONS
9.1 Someone should be within range of your voice or close enough to come to your aid when
you work near a storage battery.
9.2 Have plenty of fresh water and soap nearby in case battery electrolyte contacts skin,
clothing, or eyes.
9.3 Wear complete eye protection and clothing protection. Avoid touching eyes while working
near a storage battery.
