Base Unit Installation
Caution
Disable the machine on which the base unit is to be attached before
installation.
Use the configuration diagrams supplied by Cervis, Inc. to guide you in mounting the base unit
and connecting your wiring harness. Base unit mounting is left much to your discretion with the
following guidelines:
Make sure that the configuration diagrams supplied with the system are available. Keep
them where they can be easily accessed when needed.
Make sure the wiring harness (12-pin connector cable) is at hand.
Mount the receiver away from any intense radio or electric disturbance sources.
Mount the unit where you have enough room for your wiring harness connections.
Allow enough room to disconnect the wiring harness connector from P1 (to remove power
from the base unit, troubleshoot, etc.) when necessary.
Make sure that negative VDC (
–VDC) is directly connected to the power supply negative
terminal. Use this connection as the common for all inputs and outputs.
Make sure that the mount is secure.
Install the unit with P1 facing downward to keep water from entering the unit.
In instances where there is an external antenna, connect the external antenna only as
recommended by Cervis, Inc. with parts recommended by Cervis, Inc. (See Table 3 and
Appendix A.) Under no circumstances can a signal amplifier be used!
