5.3 Peripheral Device Installation
A wide variety of devices manufactured by Pro-face such as optional units, DIM modules and CF Cards as
well as commercial expansion boards can be used with the PL unit.
When installing the optional units, refer to each unit’s "Installation Guide".
5.3.1 Removal/Attachment of the Switch Cover
With the PL-3000B series unit, remove the switch cover to operate the internal switches or replace the
batteries for clock data backup.
Unscrew the attachment screw securing the switch cover, and remove the cover.
For the PL-3000B series unit, install the switch cover back on the control box after completing the switch
operation or the battery replacement. The torque should be 0.5 to 0.6 N•m.
Be sure to confirm that power is not being supplied to the PL unit before installing or
removing any optional units, DIM modules, CF Cards, expansion boards or other devices.
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
monitor screen connected to the front module or the PL unit is blank. Before
installing and removing the peripheral equipment, 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.
