Precaution:This manual contains important instructions that should be followed during

Monicon Instruments Co., Ltd. CHR-1285/2485
installation and maintenance of the generator and batteries.
Precaution: Read the following information carefully before attempting to install,
operate or service this equipment. Also read the instructions and information on tags, decals,
and labels that may be affixed to the transfer switch. Replace any decal or label that is no
longer legible.
Warning: Connection of a generator to an electrical system normally supplied by an
electric utility shall be by means of suitable transfer equipment so as to isolate the electric
system from utility distribution system when the generator is operating. Failure to isolate
electric system by these means may result in damage to generator and may result in injury or
death to utility workers due to back feed of electrical energy.
Monicon Instrument, Inc., hereafter referred to as the “manufacturer”, cannot anticipate
every possible circumstance that might involve a hazard. The warnings in this manual, and
on tags and decals affixed to the unit are, therefore, not all-inclusive. If using a procedure,
work method or operating technique the manufacturer does not specifically recommend,
ensure that it is safe for others. Also make sure the procedure, work method or operating
technique chosen does not render the battery charger unsafe. Throughout this publication,
and on tags and decals affixed to the battery charger, DANGER, WARNING, CAUTION and
NOTE blocks are used to alert personnel to special instructions about a particular operation
that may be hazardous if performed incorrectly or carelessly. Observe them carefully. Their
definitions are as follows:
Three commonly used safety symbols accompany the DANGER,
WARNING and CAUTION blocks. The type of information each indicates
follows:
After this heading, read instructions that, if not strictly complied
with, will result will result in personal injury, including without limitation,
death, or property damage.

Monicon Instruments Co., Ltd. CHR-1285/2485
After this heading, read instructions that, if no strictly complied
with, may result in personal injury or property damage.
After this heading, read instructions that, if not strictly
complied with, could result in damage to equipment and/or property.
NOTE:
After this heading, read explanatory statements that require special emphasis. These
safety warnings cannot eliminate the hazards that they indicate. Common sense and
strict compliance with the special instructions while performing the service are essential
to preventing accidents.
GENERAL HAZARDS 
Improper or unauthorized installation, operation, service or repair of the equipment is
extremely dangerous and may result in death, serious personal injury, or damage to
equipment and/or personal property.
Extremely high and dangerous power voltages are present inside an installed battery
charger. Any contact with high voltage terminals, contacts or wires will result in
extremely hazardous, and possibly LETHAL, electric shock. DO NOT WORK ON THE
BATTERY CHARGER UNTIL ALL POWER VOLTAGE SUPPLIES TO THE
SWITCH HAVE BEEN POSITIVELY TURNED OFF. IMPORTANT SAFETY
INSTRUCTIONS
Competent, qualified personnel should install, operate and service this equipment.
Adhere strictly to local, state and national electrical and building codes. When using this
equipment, comply with regulations the National Electrical Code (NEC), CSA Standard;
C22.1 Canadian Electric Code and Occupational Safety and Health Administration
(OSHA) have established.
Caution

Monicon Instruments Co., Ltd. CHR-1285/2485
Never handle any kind of electrical device while standing in water, while barefoot, or
while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
Jewelry conducts electricity and wearing it may cause dangerous electrical shock.
Remove all jewelry (such as rings, watches, bracelets, etc.) before working on this
equipment.
If work must be done on this equipment while standing on metal or concrete, place
insulated mats over a dry wood platform. Work on this equipment only while standing
on such insulated mats.
Never work on this equipment while physically or mentally fatigued.
Keep the battery charger enclosure closed and bolted at all times. Only qualified
personnel should be permitted access to the charger interior.
In case of an accident caused by electric shock, immediately shut down the source of
electrical power. If this is not possible, attempt to free the victim from the live
conductor but AVOID DIRECT CONTACT WITH THE VICTIM. Use a
non-conducting implement, such as a dry rope or board, to free the victim from the live
conductor. If the victim is unconscious, apply first aid and get immediate medical help.
When a battery charger is installed for a standby generator set, the generator engine may
crank and start at any time without warning. To avoid possible injury that might be
caused by such sudden start-ups, the system’s automatic start circuit must be disabled
before working on or around the generator or battery charger. For that purpose, a
SAFETY DISCONNECT is provided inside the controller panel. Always set that control
panel to its OFF position before working on the equipment. Then place a “DO NOT
OPERATE” tag on the battery charger and on the generator. Remove the Negative (Neg)
or (–) battery cable.
