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.
