NOTE : POLLUTION DEGREE 2
The inverter must be used in 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.
NOTE : ENCLOSURE SIZE FOR 75 kW TO 110 kW
The inverter, 75kW to 110kW must be installed into an enclosure with dimmensions no
less than 183cm (72 in) by 183cm (72 in) by 60cm (24 in).
NOTE : SET OF MOTOR CAPACITY AND POLES (A1, A2)
When data does not match a capacity of connected motor , it may cause unstaible motor
operation. Set proper motor capacity (kW) and motor poles even under V/F control mode.
NOTE : ENCLOSURE SIZE FOR 132 kW AND BIGGER
The inverters, 132kW and bigger, are complied as recognizedcomponents.
Therse devices are intended for use in an overall ecclosure with an internal ambient of
40 degree C for variable torque rating or 50 degree C for constant torque rating maximum.
End product temperature testing should be conducted to verify sufficient forced air ventilation
is provided to maintain this ambient in room ambient of 10-40 degree C.
Based upon component level testing , end product temperature testing may be conducted at
any convenient room ambient in the rangeof 20-40 dwgree C, unless the room ambient in the
intended application exceeds 40degree C, in which case testing should be conducted at the
elevated ambient.
Enclosure internal ambient temperature should be measured above the drive on to the upper
left or right side. Temperature measurments on the drive itself should not be necessary.

*Fasten the screws with the specified fastening torque. Check so that
there is no loosening of screws.
Otherwise, there is a danger of fire.
*Be sure to install an earth leakage breaker.
The ground fault protection is designed to detect current flowing to the
ground upon power on. This function is to protect the inverter, not
people. Install the earth leakage breaker to protect against the ground
fault on wires between the inverter and the motor. (Use a breaker that is
very sensitive to high frequency current so as not to cause malfunction.)
*Be sure to set the fuse(s) (the same phase as the main power supply)
in the operation circuit.
Otherwise, there is a danger of fire.
*As for motor leads, earth leakage breakers and electromagnetic
contactors, be sure to use the equivalent ones with the specified
capacity(rated).
Otherwise, there is a danger of fire.
*Connection to wiring terminal must be reliabily fixed with two means
of support.
