PRECAUTION
:
This is equipment should be installed, adjusted and serviced by qualified electrical
maintenance personal familiar with the construction and operation of the equipment and the hazards
involved. Failure to observe this precaution could results in bodily injury.
:
The user is responsible for ensuring that all driven machinery, drive train
mechanism not supplied by Hitachi, Ltd., and process line material are capable of safe operation at an
applied frequency of 150% of the maximum selected frequency range to the AC motor. Failure to do
so can result in destruction of equipment and injury to personnel should a single point failure occur.
:
For protection, install an earth leakage breaker with a high frequency circuit
capable of large currents to avoid an unnecessary operation. The ground faults protection circuit is not
designed to protect personal injury.
:
HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER
BEFORE WORKING ON THIS CONTROL.
:
SEPARATE MOTOR OVERCURRENT, OVERLOAD AND OVERHEATING
PROTECTION IS REQUIRED TO BE PROVIDED IN ACCORDANCE WITH THE SAFETY CODES
REQUIRED BY JURISDICTIONAL AUTHORITIES.
:
These instructions should be read and clearly understood before working on
L300P series equipment.
:
Proper grounds, disconnecting devices and other safety devices and their location
are the responsibility of the user and are not provided by Hitachi, Ltd.
:
Be sure to connect a motor thermal switch or overload devices to the L300P
series controller to assure that inverter will shut down in the event of an overload or an overheated
motor.
:
DANGEROUS VOLTAGE EXISTS UNTIL CHARGE LAMP IS OFF.
:
Rotating shafts and above ground electrical potentials can be hazardous.
Therefore, it is strongly recommended that all electrical work conform to the National Electrical Codes
and local regulations. Installation, alignment and maintenance should be performed only by qualified
personnel. Factory recommended test procedures, included in the instruction manual, should be
followed. Always disconnect electrical power before working on the unit.
NOTE : POLLUTION DEGREE 2
The inverter must be used environment of the degree 2.
Typical constructions that reduce the possibility of conductive pollution are;
1) The use of an un-ventilated enclosure
2) The use of a filtered ventilated enclosure when the ventilation is fan forced that is, ventilation is
accomplished by one or more blowers within the enclosure that provide a positive intake and
exhaust.
