Hazardous voltage.
Backfeed to the utility system can
cause property damage, severe
injury, or death.
If the generator set is used for
standby power, install an automatic

is possible whenever electricity is
present.
Open the main circuit
breakers of all power sources before
servicing the equipment. Configure the
installation to electrically ground the
generator set, transfer switch, and
related
equipment
and
circuits to comply with applicable codes
and
standards.

Safety Precautions and Instructions
Servicing the day tank. Hazardous
voltage can cause severe injury or
death. Service the day tank electrical
control module (ECM) as prescribed in
the equipment manual. Disconnect the
power to the day tank before servicing.
Press the day tank ECM OFF
pushbutton to disconnect the power.
Notice that line voltage is still present
within the ECM when the POWER ON
light is lit. Ensure that the generator set
and day tank are electrically grounded.
Do not operate the day tank when
standing in water or on wet ground
and
because these conditions increase the
risk of electrocution.
