Operations without following
instructions can cause personal
injury or damage to product or other
equipment.
1.2 Notes for Installations
Danger
!
·Please install the drive on fire-retardant material.
·Keep the drive away from combustible materials
·Keep the drive away from explosive gas
·Only qualified personnel shall wire the drive
·Never wire the drive unless the input AC supply is
totally disconnected
·The drive must be properly earthed to reduce
electrical accident
·Install the cover before switching on the drive, to
reduce the danger of electric shock and explosion.
·For drives that have been stored for longer than 2
years, increase its input voltage gradually before
supplying full rated input voltage to it, in order to
avoid electric shock and explosion
·Don't touch the live control terminals with bare
hands
·Don’t operate the drive with wet hands
·Perform the maintenance job after confirming that
the charging LED is off or the DC Bus voltage is
below 36V.
·Only trained professionals can change the
components, it is prohibited to leave wires or metal
parts inside the drive so as to avoid the risk of fire.
·Parameter settings of the control board that has
been changed must be revised, otherwise accidents
may occur.
·The bare portions of the power cables must be bound
with insulation tapes.
Attention
!
·Don’t carry the drive by its cover. The cover cannot
support the weight of the drive and may drop.
·Please install the drive on a strong support, failing
which the drive may fall off.
·Don’t install the drive in places where water pipes
may leak onto it.
·Don't allow screws, washers and other metal foreign
matters to fall inside the drive, otherwise there is a
danger of fire or damage;
·Don't operate the drive if parts are not complete,
otherwise there is a danger of a fire or human injury;
·Don't install the drive under direct sunshine,
otherwise it may be damaged;
·Don’t short circuit P1/PB and terminal (-), otherwise
there is a danger of fire or the drive may be
damaged.
·Cable lugs must be connected to main terminals
firmly
· Don’s apply supply voltage (AC 220V or higher) to
control terminals except terminals TA, TB and TC.
1.3 Notes for Using EV2000
Pay attention to the following issues when using EV2000
drive.
1.3.1 About Motor and Load
Compared to the power frequency operation
EV2000 series drives are voltage type variable speed
drive. The output voltage is in PWM wave with some
harmonics. Therefore, temperature rise, noise and
vibration of motor are higher.
Low Speed Rotating with Constant Torque
Driving a common motor at low speed for a long time,
the drive’s life will be reduced due to the deteriorating
heat dissipation effect, so a special variable frequency
motor is needed if long time operation with constant
torque is required.
Motor’s over-temperature protecting threshold
The drive can protect the motor from over-temperature.
If the ratings of the driven motor are not in compliance
