2．For the drive of 75kWG~110kWG/110kWP, the DC reactor is packed separately with a wooden box, so the
gross weight includes the weight of the DC reactor and the wooden box.
3．DC reactor should be installed at the bottom of the cabinet if it is to be installed inside a cabinet. The
clearance between reactor and the drive should be at least 35cm, and the reactor should be as far away from
the air inlet port of the drive as possible. If ventilation is poor in the cabinet, it is recommended to increase fan
forced air cooling for the reactor to avoid high ambient temperature.

Chapter 2 Drive Installation
2.1 Removal and installation of drive components
1. Lower cover 2. Operation panel 3. Upper cover 4. Dustproof plate
Fig. 2-1 Removal and installation of drive components (taking R4 as an example)
1. Removal and installation of lower cover
Removal: Loosen the fixing bolts of the lower cover with the screwdriver, press the snap-fits on both sides in
direction A, make snap-fits off with the mid-enclosure and then lift the lower cover in direction B. Now, the
lower cover is removed.
Installation: Insert the insertion piece at the top of the lower cover into the upper cover, press both sides of the
lower cover with both hands in direction A so that the snap-fits can enter into the mid-enclosure, then tighten
the fixing bolts of the lower cover with the screwdriver. Now, the lower cover is installed.
2. Removal and installation of operation panel
Removal: Insert your finger into the square hole above the operation panel, press the clip in direction C and
then separate the upper section of the operation panel with the upper cover in direction D, then separate the
connector with the operation panel. Now, the operation panel is removed.
Installation: Ensure the display of the operation panel face upwards, press the operation panel into its
box while keeping them parallel. Now, the operation panel is installed.
3. Removal and installation of upper cover
Removal: Loosen the fixing bolts of the upper cover with the screwdriver, pull in direction E to separate the
upper cover from the mid-enclosure (if necessary, press the snap-fits of the upper cover from its side with the
straight screwdriver). Now, the upper cover is removed.
Note: Do not directly remove the upper cover with the operation panel on it. The operation panel should be
removed before removing the upper cover to avoid damages to the connecting base between the operation
panel and control board, which may cause unreliable contact between the operation panel and the control
board.
Installation: Press the lower part of the upper cover in direction F so that its snap-fits can enter into the
mid-enclosure, and then tighten the fixing bolts of the upper cover with the screwdriver. Now, the upper cover
is installed.
4. Removal and installation of dustproof plate

19
Removal: It is recommended to push both snap-fits of the dustproof plate from the inside of the enclosure with
tools, so that the snap-fits can be separated from the mid-enclosure. Now, the dustproof plate is removed.
Note: Removing the dustproof plate from the outside of the enclosure directly may damage it or the
mid-enclosure.
Installation: Place the snap-fit on one end of the dustproof plate into the mid-enclosure, move the dustproof
plate to another end while pressing it till the snap-fit on another end also enters into the mid-enclosure. Now,
the dustproof plate is installed.
Note: Do not press the dustproof plate forcibly if it is deformed, otherwise, it may be damaged.
2.2 Installation environment
When selecting the installation environment, the following issues should be taken into account:
·The ambient temperature should be within -10 ~40 . If the temperature is between 40 ~50 , derating℃℃ ℃℃ is
required.
·The humidity should be within 5％~95％RH, non-condensing.
·The vibration at the installation place should be less than 5.9m/s2(0.6g).
·The device should be protected from the direct sunlight.
·The device should be mounted in the location free of dust and metal powder.
·Do not install the device in the place with corrosive gas and explosive gas.
If there is any special installation requirement, please consult our company.
2.3 Mounting direction and space
In general, the drive shall be installed vertically to avoid poor heat dissipation.
For the installation spacing and distance requirement, please refer to Fig.2-2 and Fig.2-3.
Fig. 2-2 Installation spacing for models of 45kWG/55kWP and below

20
Fig. 2-3 Installation spacing for models of 55kWG/75kWP and above
When more than two drives are mounted in the up-down installation mode, the partition plate should be
installed between them, so as to avoid the influence of the heat dissipation from the bottom drive on the top
one, as shown in Fig.2-4.
