IMPORTANT SAFETY INSTRUCTIONS
PowerMaster Technical Manual
ELECTRICAL HAZARDS
All generators covered by this manual produce
•
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch
as does the standby generator when it is in operation. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure
all appropriate covers, guards and barriers are in
place before operating the generator(s). If working
around an operating unit, stand on an insulated,
dry surface to reduce shock hazard.
Do not handle any kind of electrical device while
•
standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
The National Electrical Code (NEC) requires the
•
frame and external electrically conductive parts
of the generator to be connected to an approved
earth ground and/or grounding rods. Local electrical codes also may require proper grounding of the
generator electrical system.
After installing this standby electrical system, the
•
generator(s) may crank and start at any time without warning. When this occurs, load circuits are
transferred to the STANDBY (generator) power
source. To prevent possible injury if such a start
and transfer occur, always set the generator’s
AUTO/OFF/MANUAL switch to its OFF position
before working on equipment and remove the
negative battery lead.
In case of accident caused by electric shock, imme-
•
diately shut down the source of electrical power.
If this is not possible, attempt to free the victim
from the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting implement, such as a rope or board, to free the victim
from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
Never wear jewelry when working on this equip-
•
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.
The enclosure door on this unit is grounded to the
•
chassis with a wire. The grounding wire must be
reconnected when the door is replaced to reduce
the risk of electric shock.
FIRE HAZARDS
For fire safety, the generator(s) must be installed
•
and maintained properly. Installation always must
comply with applicable codes, standards, laws
and regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator(s) is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
Keep a fire extinguisher near the generator(s) at all
•
times. Extinguishers rated “ABC” by the National
Fire Protection Association are appropriate for
use on the standby electric system. Keep the extinguisher properly charged and be familiar with its
use. If there are any questions pertaining to fire
extinguishers, consult the local fire department.
EXPLOSION HAZARDS
Do not smoke around the generator(s). Wipe up
•
any fuel or oil spills immediately. Ensure that no
combustible materials are left in the generator(s)
compartment, or on or near the generator(s), as
FIRE or EXPLOSION may result. Keep the area
surrounding the generator(s) clean and free from
debris.
