Battery Charger RE
User's Manual
2. Safet 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
