Incorrect handling m ay cause hazardous conditions, resulting in death or severe injur y.

Incorrect handling m ay cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

1. Electric Shock Prevention

WARNING

z While power is ON or when the inverter is running, do not

open the front cover. Otherwise you may g et an electric shock.

z Do not run the inverter with the front cover or wiring cover

removed. Otherwis e you may access the exposed highvoltage terminals or t he charging part of the ci rcuitry and get an electric shock.

z Even if power is OFF, do not remove the front cover

except for wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.

z Before wiring or insp ection, power must be sw itched OFF.

To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring o r inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are n o residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other appli cable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

z Any person who is involved in wiring or inspection of this

equipment shall be f ully competent to do the wor k.

z The inverter must be installed before wiring. Otherwise

you may get an elect ric shock or be injured.

z Setting dial and key operations must be performed with

dry hands to prevent an electric shock.

z Do not subject the c ables to scratches, excess ive stress,

heavy loads or pinc hing. Otherwise you may get an electric shock.

z Do not change the cooling f an while power is ON. It is

dangerous to change the cooling fan while power is ON.

z Do not touch the printed circuit board or handle the

cables with wet hands. Otherwise you may get an electric shock.

z When measuring th e main circuit capacitor ca pacity, the

DC voltage is applied to the motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powerin g OFF to prevent an e lectric shock.

2. Fire Prevention

CAUTION

z Inverter must be installed on a nonflammable wall without

holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

z If the inverter has become faulty, the inverter pow er must

be switched OFF. A continuous flow of large current could cause a fire.

z When using a brake res istor, a sequence that will turn OFF

power when a fault signal is output must be configured. Otherwise the brak e resistor may overheat due to damage of the brake transi stor and possibly cause a fire.

z Do not connect a resistor directly to the DC terminals P/+

and N/-. Doing so could cause a fire.

3.Injury Prevention

CAUTION

z The voltage applied to each terminal must be the ones

specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.

z The cables must be connected to the correct terminals.

Otherwise burst, dam age, etc. may occur.

z Polarity must be cor rect. Otherwise burst, damage, etc.

may occur.

z While power is ON or for some time after power-OFF, do

not touch the inver ter as they will be extr emely hot. Doing so can cause burns.

NOTE

y The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as

possible within the p ermissible range. This m ust be noted especi ally when the inverter is installed in an enclosure. (Refer

to page 8)

y Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit

to protect them from noise. (Refer to page 9)

y Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.

This will cause the i nverter to trip or the c apacitor and surge suppress or to be damaged. If any of the above dev ices are connected, immediately remove them.

y Electromagne tic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install options among the capacitor type EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC filter to minimize the interferen ce. ( Refer to Chapter 3 of the Instruction Manual (Applied)).

NOTE

y Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely c an cause a short circuit

or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.

y Use crimping terminals with insulation sleeve to wire the power supply and motor.

Wiring

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the

motor terminals, deteriorating the insulation of the motor. Take the following measures 1) or 2) in this case.

1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection

according to wiring length.

Carrier frequency 14.5kHz or less 8kHz or less 2kHz or less

2) Connect the surge voltage su ppression filter (FR-ASF- H/FR-BMF-H) o n the inverter output side.

NOTE

y Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side. If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention

function occurs, incre ase the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention

operation selection in Chapter 4 of the Instruction Manual (Applied))

y When using the automatic restart after instantaneous power failure function with the wiring length exceeding 100m,
