5.3 How to Remove a Door
If it is absolutely necessary to remove a door during maintenance, refer to FIGURE 5-2 and
remove the grounding wire from the fixing bracket at the upper part of the door and the
hinge parts. Then, lift the door to disengage it. Keep the removed door in a safe place.
The detailed procedure below explains how to remove a door. Most of the steps are the
same when applied to the front or rear door.
1. Remove the operator panel from the front door. This step is not required for the rear
door.
a. Unhook the cable holders to free the cables of the operator panel.
b. Using a Phillips screwdriver, loosen the two screws securing the operator panel,
and remove the operator panel from the front door.
c. Affix the operator panel to some convenient location on the cabinet.
Note – If the operator panel need not be removed for maintenance, you can remove the
cables from the sensor unit side.
2. Remove the screw securing the upper hinge bracket on the right, and remove the
grounding wire as well.
3. While supporting the door with one hand, loosen the screw securing the upper hinge
bracket on the left.
4. Lift the door, and remove it from the lower hinge bracket.
