11. Special Usages
T he user can consult our compa ny if he wants to use another method instead of the recommended
connecting method provide d in the manual, s uch as shared DC bus.
12. Cautions for Scr ap of Inverter
T he e lectrolytic capaci tors in the main ci rcui ts and PCB may explode when they are bur ned a nd poisonous
gas may be generated when the plastic parts are bur ned. Please dispose the inverter as industrial rubbish.
13. About Applicable Motor
1) The sta ndard motor used is the 4-pole squirrel cage as ynchronous induction motor. If other kind of
motor is used, pl ease be sure to select the applica ble i nverter acc ording to the rated curr ent of the motor,
and pl ease consult us if the user wants t he inverte r t o drive the permanent magne tic synchronized motor.
2) The cooling fan of non-variable frequency motor is connected to the rotor in the s ame bearing, so the
cooling effect is weakened if the speed is low, t here fore use the variable-frequency motor or ins tall a
cooling fan in the ove rheat condition the motor.
3) The inverter has already been configured with the standard parameters for applicable motor, pleas e
be sure to modify the default values or perform the motor parameter identification according to the
actual condi tions, other wis e the operation effect or prot ection performance may be reduced.
4) Short-circ uit in the cable or motor may ca use the inverter alar m or even damage t he inverter.
T herefor e, pleas e conduct the insulat ion short-circuit test to t he cable and the motor installed for the
first time. The short-c ircuit test shal l also be car ried out in routine maintenance . Pay attention that the
inverter shall be separated from the unit during such test.

The AC motor dri ve has gone through rigorous qua lity control tests at the factory before shi pment.
After re cei ving the AC drive, c heck for the following.
Receiv ing
1.Check to make sur e t hat t he package includes an AC drive,the User Ma nual,dust covers and
rubber
bushings.
2.Inspect the unit to insure it was not damaged duri ng shi pment.
3.Make sure that the par t numbe r indicat ed on the name plate corres ponds wi th the part number of your
order.
Storage
The AC Dri ve shoul d be kept in the s hipping carton before ins tall ation. In order to retain the war rant y
cove rage, the AC drive should be stored properly when it is not to be used for an extended period of time.
Some storage suggestions are:
1. St ore in a clean, dry l ocat ion.
2. St ore wi thi n an ambient temperature ra nge of -20
C to +65
C.
3. If possible, store in an air-conditioned environme nt where the relative humidi ty is less than
95%, non-condensi ng.
4. Do not store the AC dri ve i n pl aces where it could be expose d t o corrosive gas es.
5. Pl ease store the AC drive on a shel f or on an stable surfa ce.
