Thank you for purchasing the CX1000.
This manual contains simple explanations about how to install and connect
the CX1000. For more information about the procedures described herein,
safety precautions, and the CX1000 functions and operation, please refer to
the PDF manual found on the provided CD-ROM.
Installation Procedure
1. Cut the instrument panel according to the diagram below.
For the panel cut dimensions when installing multiple units closely
together, see the
CX1000 User’s Manual IM 04L31A01-03E
found on
the provided CD-ROM.

2. Insert the CX1000 into the front of the panel.
3. Using the mounting brackets that came with the package, attach the
CX1000 to the panel as shown in the following figure.
First, attach the two mounting brackets and temporarily fasten the
attachment screws. Next, fix the CX1000 in place by tightening the
attachment screws with the appropriate torque (0.7 to 0.9 N-m.). As you
fasten the screws, press the mounting bracket against the case so that
they are in contact with each other.

Connecting the Power Supply
When using electrical wiring, be certain to follow the safety
recommendations prescribed in the CX1000 User's Manual.
Use a power supply that meets the following conditions:
Rated supply voltage:
100 to 240 VAC
Supply voltage range used:
90 to 132, 180 to 264 VAC
Rated supply voltage frequency:
50/60 Hz
Permitted supply voltage frequency range:
50/60 Hz
±
2%
Maximum power consumption:
39 VA (100 V), 51 VA (240 V)
1. Turn OFF the CX1000 and open the cover (transparent) for the
power supply wires.
2. Connect the power cord and the protective ground cord to the power
supply terminals.
