This section of the Operation Manual describes
electric motor operation procedures.
Before you perform any electric motor operation
procedures, read “Section 2 SAFETY” and the
following safety messages.
WARNING! The following safety messages
address a potential Electrical Shock Hazard
while operating and servicing the electric
motor:
• Always turn off the power supply equipment
breaker immediately in the event of an
emergency during operation.
• Always turn off the power supply equipment
breaker immediately in the event of a power
failure during operation. The machine may
be operated after the breaker is reset and the
machine is restarted.
• Always turn off the power supply equipment
breaker and wait at least 10 minutes before
performing inspection and maintenance on
the electric system. Before performing any
procedures, use a voltmeter to verify no
voltage is present at the power supply box.
• Alert all personnel of your actions before
performing inspection and maintenance on
the electric system. Attach a “DO NOT
TOUCH” warning tag on the power supply
equipment breaker.
• Always use caution when performing
inspection and maintenance procedures on
the electric system. Be sure of your action
prior to performing inspection and
maintenance on the electric system.
• Do not expose the power supply box and the
inverter to water.
WARNING! Burn Hazard. Do not touch any
electric system components immediately after
the machine is operated. Be sure the
component is cool to the touch before
performing inspection and maintenance on
the electric system.
IMPORTANT: The hydraulic oil is cooled by
the engine fan blowing air through the oil
cooler to cool it. The engine fan is only turning
when the engine is running. Continuous
electric motor crane operation may raise the
hydraulic oil temperature. Pay close attention
to hydraulic oil temperature during electric
motor crane operation. The crane may need to
be periodically shut down to allow the
hydraulic oil to cool off.
