2. Safety instructions and warnings
GENERAL
Battery chargers can cause injury or death, or damage to other equipment or property, if the user does not strictly observe
all safety rules and take precautionary actions. Safe practices must be learned through study and training before using this
equipment. Only qualified personnel should install, use, or service this battery charger.
SHOCK PREVENTION
Bare conductors, or terminals in the output circuit, or ungrounded, electrically-live equipments can fatally shock a person.
To protect against shock, have competent electrician verify that the equipment is adequately grounded and learn what
terminals and parts are electrically HOT. The body’s electrical resistance is decreased when wet, permitting dangerous
current to flow through the body. Do not work in damp area without being extremely careful. Stand on dry rubber mat or
dry wood and use insulating gloves when dampness or sweat cannot be avoided. Keep clothing dry.
INSTALLATION AND GROUNDING – Electrical equipment must be installed and mantained in accordance with all the applicable
national and local codes. A power disconnect switch must be located at the equipment. Check the data label for voltage and phase
requirements. If only 3-phase power is available, connect single-phase equipment to ONLY TWO WIRES of the 3-phase line. DO
NOT CONNECT the equipment grounding conductor to the third live wire of the 3-phase line as this makes the equipment frame
electrically HOT, which can cause a fatal shock. If a grounding conductor is part of the power supply cable, be sure to connect
it to a properly grounded switch box or building ground. If not part of the supply cable, use a separate grounding conductor.
Don’t remove a ground prong from any plug. Use correct mating receptacles. Check ground for electrical continuity before using
equipment. The grounding conductor must be of a size equal to or larger than the size recommended by Code or this manual.
CHARGING LEADS – Inspect leads often for damage to the insulation. Replace or repair cracked or worn leads immediately.
Use leads having sufficient capacity to carry the operating current without overheating. Never extend the charging leads
without prior approval of the manufacturer. Extending the charging leads without prior approval of the manufacturer may
cause wrong operation of the charger and voids the warranty.
BATTERY TERMINALS – Do not touch battery terminals while equipment is operating.
SERVICE AND MAINTENANCE – Shut OFF all power at the disconnect switch or line breaker before inspecting, adjusting,
or servicing the equipment. Lock switch OPEN (or remove line fuses) so that the power cannot be turned ON accidentally.
Disconnect power to equipment if it is to be left unattended or out of service. Disconnect battery from charger. Measure
voltage on capacitors and, if there is any voltage reading, wait 5 minutes before to proceed.
Keep inside parts clean and dry. Dirt and/or moisture can cause insulation failure. This failure can result in high voltage at the
charger output.
BURN AND BODILY INJURY PREVENTION
The battery produces very high currents when short circuited, and will burn the skin severely if in contact with any metal
conductor that is carrying this current. Do not permit rings on fingers to come in contact with battery terminals or the cell
connectors on top of the battery. Battery acid is very corrosive. Always wear correct eye and body protection when near batteries.
FIRE AND EXPLOSION PREVENTION
When batteries are being recharged, they generate hydrogen gas that is explosive in certain concentrations in air (the
flammability or explosive limits are 4.1% to 72% hydrogen in air). The spark-retarding vents help slow the rate of release of
hydrogen, but the escaping hydrogen may form an explosive atmosphere around the battery if ventilation is poor.
The ventilation system should be designed to provide an adequate amount of fresh air for the number of batteries being
charged. This is essential to prevent an explosion. Always keep sparks, flames, burning cigarettes, and other sources of
ignition away from the battery recharging area. Do not break “live” circuits at the terminals of batteries. Do not lay tools or
anything that is metallic on top of any battery.
To prevent arcing and burning of the connector contacts, be sure the charger is OFF before connecting or disconnecting
the battery. The digital display must be completely OFF.
