3.2.2 Removing and Mounting of Cover
EV2000 series have two kinds of cover, plastic or
metallic one. Follow the steps below to remove and
mount the cover.
1. Removing and mounting of plastic covers
1) Removing:
① Remove the operation panel
② Remove two screws at bottom
③ Lift the bottom of cover up to 5~10 degrees, move it
upward at least 10mm until the clamp are out of the slot
on the cabinet, then remove the front panel.
2) Mounting of plastic cover:
①Tilt the cover 5~10 degree;
②Insert the top clamp into the slot at the top of the
drive;
③Mount the screws at the bottom part of the cover;
④Install the operation panel

     Note:
Pull out or insert the plastic cover gently, otherwise the
mounting clamp may be damaged.
2. Procedures of removing and mounting the metal
cover
1) Procedures of removing the metal cover:
①Remove the operational panel;
②Remove all the screws on the cover;
③Take out the cover horizontally.

3.3 Wire Connections of Drive
! Danger
·Wiring can only be done after the drive’s AC
power is disconnected, all the LEDs on the
operation panel are off and waiting for at least 5
minutes. Then, you can remove the panel.
·Wiring job can only be done after confirming the
charge indicator on the right bottom has
extinguished and the voltage between main circuit
power terminals + and - is below DC36V.
·Wire connections can only be done by trained and
authorized personnel.
·Check the wiring carefully before connecting
emergency stopping or safety circuits.
·Check the drive’s voltage level before supplying
power to it, otherwise human injuries or equipment
damage may happen.
! Attention
·Check whether the Variable Speed Drive’s rated
input voltage is in compliant with the AC supply
voltage before using.
·Dielectric strength test of the drive has been done
in factory, so you need not do it again.
·Refer to chapter 2 on connected braking resistor
or braking kit.
·It is prohibited to connect the AC supply cables to
the drive’s terminals U, V and W.
·Grounding cables should be copper cables with
section area bigger than 3.5mm2
, and the
grounding resistance should be less than 10Ω.
·There is leakage current inside the drive. The total
leakage current is greater than 3.5mA, depending
on the usage conditions. To ensure safety, both the
drive and the motor should be grounded, and a
leakage current protector (RCD) should be
installed. It is recommended to choose B type RCD
and set the leakage current at 300mA.
·The drive should be connected to the AC supply
via a circuit breaker or fuse to provide input
over-current protection or convenience for
disconnecting the AC supply to maintain the drive.
Wire the drive according to Fig. 3-7 during

1). Isolation switch should be connected between the
AC supply and the drive to ensure the safety of the
maintenance engineer.
2). Circuit breaker (QF) or fuse should be connected
between the AC supply and the drive to isolate the fault
of other equipment. Refer to Table 3-1 for the selection
of circuit breaker.
3) When a contactor is used for controlling the AC
supply, don’t use it to switch on or off the Variable
