5.2.1 PL-3600T Series
„ Removing the front module and the control box
Remove the control box from the front module with the following steps:
(1) Unscrew the attachment screw securing the flexible cable cover and remove the cover.
Be sure to confirm that power is not being supplied to the PL unit before installing or
removing the front module and the control box. Failure to do so can result in an electric
shock.
• In the Soft OFF status, power is supplied to some of the circuits even when the
screen of the front module is blank. Before removing the control box, be sure to
confirm that its power supply switch is OFF or its power cable is not connected.
• Use a screwdriver to loosen or tighten the screws. Be sure not to tighten screws
too tightly, since it may damage the unit.
• When removing or replacing screws, be careful that they do not fall inside the PL
unit’s chassis.
