Note: Always power down machine prior to Installation.
The cashbox does not lock to the chassis. When you remove the unit from the container or when the unit is not installed in the machine, you must
never carry the note acceptor by the handle of the cashbox. The cashbox may release causing the rest of the unit to fall and damage the
chassis.
Installing the Chassis
• Most models have a configuration-specific harness installed
on the back of the chassis (see Interface Manual p/n
252058039 for more details). Connect the harness from the
chassis to the host machine. Always dress all wires to avoid
interference with any equipment operation.
Note: If you have a custom configuration, you may need to contact our technical support group for assistance.
• Once the connections are made, you will need to line up the locating holes on the bottom of
the chassis with the machine’s locating pins. Line up the mounting screw holes and insert M4
screws through several of the 10 mounting holes. There are three on each side of the chassis and
four located on the back. Leave screws slightly loose until the entry guide is mounted and aligned
with the machine door closed. Screws must not exceed a 6mm depth through the mounting plate,
otherwise they may interfere with the removable cashbox.
Earth Grounding Considerations:
Use star washers when mounting the chassis via the back or side mounting options. If the side
mounting option is selected, use the lower mounting holes with an M4 screw to ensure a bonded
connection to the host machine.

Inserting and Removing the Acceptor Module
• Insert the Acceptor Module so that the release lever locks into place. The acceptor should be
firmly seated to ensure proper engagement of the
locking feature.
• To remove the unit, pull upwards on the release lever
located on the front of the Acceptor Module and pull
away from the chassis.
