TP-5660 11/98 Safety Precautions and Instructions III
Installing accessories to
transformer assembly. Hazardous
voltage can cause severe injury or
death. To prevent the possibility of
electrical shock, disconnect harness
plug before installing any accessories
involving connection to transformer
assembly primary terminals 76, 77, 78,
and 79. Terminals are at line voltage!
(Models with E33+, S340, S340+, 340,
R340, or R33 controls only.)
Installing accessories to
transformer assembly. Hazardous
voltage can cause severe injury or
death. To prevent the possibility of
electrical shock, disconnect harness
plug before installing any accessories
which will be connected to transformer
assembly primary terminals on
microprocessor logic models.
Terminals are at line voltage!
Making line or auxiliary
connections. Hazardous voltage
can cause severe injury or death. To
prevent the possibility of electrical
shock, deenergize the normal power
source before making any line or
auxiliary connections.
Short circuits. Hazardous
voltage/current can cause severe
injury or death. Short circuits can
cause bodily injury and/or equipment
damage. Do not contact electrical
connections with tools or jewelry while
making adjustments or repairs.
Remove wristwatch, rings, and jewelry
before servicing equipment.
Servicing the transfer switch.
Hazardous voltage can cause
severeinjuryor death. Deenergizeall
power sources before servicing. Open
main circuit breakers of all power
sources to the transfer switch and
disable all generator sets as follows:
1) Move all generator set master
controller switches to the OFFposition.
2) Disconnect power to all battery
chargers. 3) Disconnect all battery
cables, negative (--) leads first.
Reconnectnegative(--)leadslastwhen
reconnecting battery cables after
servicing. Follow these precautions to
prevent starting of generatorsets by an
automatic transfer switch, remote
start/stop switch, or engine start
command from a remote computer.
Servicing transfer switch controls
and accessories within the
enclosure. Hazardous voltage can
cause severe injury or death.
Disconnect transfer switch controls at
the inline connector to deenergize the
circuit boards and logic circuitry but
allow the transfer switch to continue to
supply power to the load. Disconnect
all power sources to any accessories
mountedwithin theenclosure butwhich
are not wired through the controls and
deenergized by inline connector
separation. Test circuits with a
voltmeter to verify that they are
unpowered before servicing.
Heavy Equipment
Unbalanced weight.
Improper lift can cause severe
injury or death and/or equipment
damage.
Use adequate lifting capacity.
Never leave transfer switch standing
upright unless it is securely bolted in
place or stabilized.
